In operation, double-face imaging direct heat printer 10 can be attempted coming thermal imaging medium 20 with the first and second thermal printer heads 50 and 60.In such trial, can select the first print data to be used for being printed by the first thermal printer head 50 from first memory or buffer 80, select the second print data to be used for being printed by the second thermal printer head 60 from second memory or buffer 80.If after being attempted by the printing of the first thermal printer head 50, sensor 100 is not sensed the first print data of selection, can generate so first and print failure signal.Then the first printing failure signal like this can be used for generating the one or more inside (for example printer 10) and/or outside (computer or the terminal that for example are connected) that are used for the operator and notify, and/or be used for automatically starting or forbid the function of one or more printers 10, for example forbid the further printing by the first thermal printer head 50.Similarly, after being attempted by the printing of the second thermal printer head 60, if sensor 102 is not sensed the second print data of selection, can generate second by sensor 102 and print failure signal.Then the second printing failure signal like this can be used for generating the one or more inside (for example printer 10) and/or outside (computer or the terminal that for example are connected) that are used for the operator and notify, and/or be used for automatically starting or forbid the function of one or more printers 10, for example forbid the further printing by the second thermal printer head 60.
In the situation that one or more sensors 100 and 102 are installed in contiguous the first and second thermal printer heads 50 and 60, can carry out a large amount of operations and/or notice.For example, in one embodiment, thermal medium can be indicated by first sensor 100, and non-thermal medium can by the second sensor 102 indications, cause the installation indication of directed single face thermal medium 20 for being printed on first surface by printer 10.Under these circumstances, the first thermal printer head 50 can manually or automatically be started to be used for printing, and the second thermal printer head 60 can manually or automatically be forbidden printing.Similarly, in another embodiment, non-thermal medium can be indicated by first sensor 100, and thermal medium can by the second sensor 102 indications, cause the installation indication of directed single face thermal medium 20 for being printed on second by printer 10.Under these circumstances, the first thermal printer head 50 can manually or automatically be forbidden to be printed, and the second thermal printer head 60 can manually or automatically be started for printing.In above-mentioned every kind of situation, also can provide one or more operator notifications, for example indicate the printing that the message of single face or non-Double-side hot medium has been installed by the thermal printer head of each operation.
In another embodiment, thermal medium 20 can by the first and second sensors 100 and 102 both indications, form the indication of installing for the Double-side hot medium of all printing on its first and second.In this case, arbitrary in the first and second thermal printer heads 50 and 60 or both printings can manually and/or automatically be started.Similarly, in another embodiment, can indicate non-thermal medium when both indicating non-thermal medium by the first and second sensors 100 and 102.In this case, the first and second thermal printer heads 50 and 60 both printings can manually and/or automatically be forbidden, and/or operator notification can be provided, for example the warning of one or more sense of hearings, vision and/or the sense of touch of non-thermal medium has been installed in indication.
In all cases, can automatically provide in response to the one or more signals from one or more sensors 100 and/or 102 startup and/or the forbidding of one or more printing functions, for example by the printing of the first and/or second thermal printer head 50 and 60.Similarly, can select to provide by the manual printing model after operator notification startup and/or the forbidding of one or more printing functions.Above-mentioned modification comprises combination manually and automatic scheme (for example automatic printing model selection and manual operation person cancel) also is fine.
In optional embodiment, before for example changing manually or automatically one or more printer function, can compare with one or more printing model settings from the result that the print media type is determined.Such printing model setting can be stored in one or more memories or buffer 80 of printer 10.In one embodiment, be arranged at printer in the situation that be used for the single face printing on the first surface of thermal medium 20, be Double-side hot medium or the location is used in the situation that the single face thermal medium of printing on first surface at the medium of determining to install, can not guarantee or carry out change manually or automatically to printing model.Yet, be arranged at printer similarly in the situation that be used for single face on the first surface of thermal medium 20 and print, the medium of determining to install be the location be used for printing on second the single face thermal medium time, can require or carry out manual and/or automatic change to printing model.Other combination and/or modification to such scheme are fine certainly.Further, in the situation that there are conflict in the media type that detects and one or more printing model between arranging, except or substitute and to carry out any manual and/or automatic printer function and/or schema modification, also can point out the user to change and/or replace medium 20.
In practice, two-sided direct thermal imaging printer 10 can be configured in response to various printer operation, condition and/or input except other things, carries out the operation of print media type checking manual and/or automaticly.For example, in one embodiment, print media inspection (for example operator's selection) as required occurs.In another embodiment, such print media inspection can periodically occur at the one or more fixed number of times except other things and/or interval.Additionally or alternatively, particular event can trigger such print media inspection operation, and this particular event comprises that the powering on of printer 10 except other things, printer 10 are to the connection of the external equipment of for example computer or terminal (not shown) and/or the replacement of medium 20.
In the situation that replace or additional print media 20, can trigger the print media inspection from one or more signals of the one or more medium sensors that are associated with printer 10.Such medium sensor can comprise one or more medium sensor installations, medium quantity sensor and one or more media type sensor.In one embodiment, the medium inlet signal after medium goes out signal (having replenished medium) can trigger the execution that print media checks.Similarly, in the situation that printer 10 powers on, can carry out the print media inspection as one of pre-operation printer diagnosis array.
In any case, can the startup that print media checks occur in response to single triggering or order, perhaps the print media inspection can occur due to a plurality of triggerings or order.Similarly, as the execution condition before that print media checks, the startup of print media inspection may require the signal that provides extra and/or need to satisfy extra allowing (permissive).Such extra or allow and to comprise the printer shutdown signal, this signal is provided by the one or more contacts except other things or limit switch (seeing the limit switch 420 in Fig. 6 for example), the memory of the buffer 80 that is stored in printer 10 is allowed in indication for the print media inspection data storage of the print data piece that carries out the medium inspection, etc.In one embodiment, printer 10 can be configured to not install when medium sensor indication and not carry out the print media inspection when medium and/or medium are arranged in printer irrelevantly.
Fig. 1 E has illustrated an embodiment of the method 600 of the print media inspection of being carried out by double-face imaging thermal printer 10.Initially, in step 610, printer 10 receives and/or processes order or other triggering that starts the print media inspection.In step 620, check one or more allow with the one or more conditions of checking before carrying out the print media inspection be satisfied.the indication that can comprise except other things of allowing like this has the signal from paper sensor (for example paper sensor in Fig. 5 360) of medium 20 in printer 10, indication printer 10 is used for printing the signal from one or more limit switches 420 of (for example the pivotable support arm of Fig. 6 or cover 300 by suitably closed and/or be matched with lower arm or the pedestal of printer 200) by correct assembling, the signal that transaction has been completed is printed in indication, indicate the signal of suitable printing test message in memory or buffer 80, and/or indication motor, voltage, and the state of thermal printer head 50 and 60 all is suitable for one or more signals that (for example there is no fault condition) prints.
One or more when allowing when having satisfied, in step 630, obtain for the print media of being attempted printing by the first and/or second thermal printer head 50 and 60 and check data.Such print media checks that data can comprise text (such as ASCII, Kanji etc.) and/or figure, and comprise one or more message (for example, the message in Fig. 2 A and 2B 708 and 728), one or more image (such as the image 706 and 726 in Fig. 2 A and 2B), one or more sign (such as the sign 766 in Fig. 2 D) etc.In one embodiment, print media checks that data comprise one or more bar codes or other machine-readable character (for example bar code 710 in Fig. 2 A, 2B and 2C, 746 and 748).Further, can receive print media from the computer of communicating by letter with printer 10 or terminal and check data, perhaps obtain from one or more memories or the buffer 80 that is associated with printer 10.In one embodiment, obtain print media from the EEPROM that is associated with printer 10 and check data.
In case be acquired, attempt in step 640, check the one or both sides of data imaging medium 20 to use print media.As shown in Fig. 2 A and 2B, such trial can comprise each face 704 and 722 of attempting using bar code 710 image forming mediums 700 and 720.Similarly, as shown in Fig. 2 C, such imaging is attempted comprising the first surface 742 of attempting using article one shape code 746 image forming mediums 740, and is used second 744 of second shape code 748 image forming mediums 740.Additionally or alternatively, such imaging is attempted comprising and is used identical print media to check first and second 762 and 764 of data imaging print media 760, is to indicate that 766 form is depicted as image here.Medium appoint on one or both sides print media with forms such as other symbol, image, text, message to check the trial of data and/or actual to print that yes possible.
In step 650, in attempting obtaining indication prints expection on the one or both sides of medium 20 print media and checking the success or failed sensing data of data, obtain one or more signals from one or two sensor 100 and 102.Can print side by side or attempt obtaining such a or a plurality of sensor signal after printing is completed with attempting.Similarly, can obtain such sensor signal after moving to the delay relevant with 102 position of each sensor 100 from each printhead 50 and 60 with for example medium.Any such delay of obtaining one or more sensor signals can be taken into account in media recognition that the print media audit program carries out and/or checking in processing a part and as the part of this processing.
According to the type of sensor 100 and 102, any sensor signal of obtaining like this can through conversion or other conversion, comprise analog to digital conversion and/or fast Fourier transform (FFT) except other things.
In step 660, check that from print media the sensor signal data of obtaining the successful printing of data compares from the data quilt of the sensor signal after original and/or conversion and expection.As checking data for print media, can receive such expection sensing data from the computer of communicating by letter with printer 10 or terminal, perhaps obtain the sensing data of such expection from one or more memories or the buffer 80 that is associated with printer 10.In one embodiment, obtain the sensing data of expection from the EEPROM that is associated with printer 10.
The sensing data that obtains and the sensing data of expection relatively can comprise comparison except other things the one or more voltages, electric current and/or the bitmap that are associated with sensor 100 and/or 102 and with voltage, electric current and/or the bitmap of one or more expections of being associated of signal data of expection.Further, so relatively can comprise determine to have or do not have extra process from the data of one or more sensor signals in predetermined tolerance limit (for example+/-predetermined figure in predetermined voltage, scheduled current level and/or bitmap) whether mate the sensing data of expection.Yet, should be noted that binary system (for example 1/0, sensed/not sensed) signal and be more also possible.
In step 670, according to whether find coupling between the signal data of indication from the data of one or more signals of one or more sensors 100 and 102 and expection, (success) just can be provided or bear the test result of (failure).As shown in Fig. 2 A and 2B, such indication can be included in positive test pattern 726 and/or positive test post 728 or negative testing image 706 and/or the negative testing message 708 that is printed on the one or both sides of each medium 700 and 720.Similarly, such indication can be included in to exist on the one or both sides of print media or do not exist with print media and check one or more message or the image that data are associated, for example in Fig. 2 B in the existence of the bar code 710 on the face 722 of medium 720 and/or Fig. 2 A and 2C on each face 704,742 and 744 of medium 700 and 740 bar code 710,746 or 748 do not exist.
Provide printing trial and success or failed indication also can comprise and generate the success of indication print media inspection or the failed sense of hearing, vision or other (for example sense of touch) notice.Additionally or alternatively, such indication can comprise that generating indication prints success or the failed one or more signals of attempting, and/or the type of the medium of installing in printer 10 and/or direction (for example Double-side hot medium, directed being used at the single face thermal medium of printing on first surface, directed single face thermal medium or non-thermal medium for printing on second).
As shown in step 680, the indication that generates like this and/or signal can be used for manual and/or automatic startup and/or the forbidding of one or more functions of prompting printer 10.In one embodiment, single face or non-thermal medium are installed in signal in printer 10 or other indication and can be used for prompting or require the operator before using, double side dielectric being installed at further printer.Additionally or alternatively, such signal or the indication suitable printing model of media type that can be used for prompting or require the operator to select and install.Similarly, indication is printed the print media of selecting and is checked that the success of data or failed signal can be for the suitable printing models of media type that automatically arranges and install on the one or both sides of print media.Such automatic printing model selection can comprise startup except other things or forbidding by the printing of the first thermal printer head, startup or forbidding by the printing of the second thermal printer head start or forbidding by both printings of the first and second thermal printer heads.In one embodiment, when sensing non-thermal medium, can forbid the function of all printers 10, and can point out the user to replace with single face and/or Double-side hot medium the medium of installing before printing continuation.
should be noted that and check position on the medium of installation of data at print media as shown in Fig. 2 A to 2D, the position (for example position of the printing of the trial of the bar code 710 on the face 704 of the medium 700 in Fig. 2 A) that comprises the printing of trial, such as the indication (such as the position of the positive test post 728 on the face 724 of Fig. 2 B medium 720) of the printing success of the indication of the printing of the media type of installing or failed printing etc., it can be according to the software of computer system and/or printer 10, firmware, hardware and/or comprise makes thermal printer head 50 and 60 operations along the spacing in feeding medium path, the direction of printing etc., the medium size, configuration and/or comprise medium whether to comprise the type of pre-type information and change.
In a further embodiment, expection print media on the one or both sides of medium checks the existence of data or does not exist, one or more signs 766 on the first surface 762 of print media 760 and/or second 764 in Fig. 2 D for example, can provide to the user of printer 10 suitable media type installation indication and point out where necessary further user intervention.In one embodiment, such print media inspection can occur in the situation of any installation of not having one or more media type sensors 100 and 102 or use.
In other embodiments, can confirm the background signal from one or more sensors 100 and 102 for blank (for example non-thermal imaging) medium by the induction blank medium before attempting imaging.Then relatively after attempting, imaging can use such background signal from one or more sensors 100 and 102 signal datas that obtain with when expecting signal data (for example step 660 Fig. 1 E).In such embodiment, whether at definite hot print during success, the one or more differences between the signal that obtains after hot print is attempted and the background signal that obtained before hot print is attempted can and be expected and compared aspect signal one or more.In optional embodiment, the expection background signal data that are used for the optional media type of one or more users also can be used for the media type that identification is installed.
As mentioned above, print media checks that data can comprise any combination of text, figure and/or other machine readable and/or the cognizable information of user.In addition, can select identical or different print media to check that data are used for printing on one or two face of print media.Similarly, in the embodiment that has, can or not carry out the print media inspection on (for example print media checks disabled) print media 20 at a face of medium 20, two faces.
Except success that print to attempt or failed indication are provided, comprise providing the indication of media type of installation and/or the one or more printer function of startup/forbidding to be stored in to be connected with printer in one or more memories of being associated or buffer positions 80 and/or being sent to computer or the terminal of connection to the user except other things by what the print media inspection caused.In one embodiment, can set up success and/or failure that fault log checks with the print tracking medium, and/or the amount of the number of times of the printer configuration (for example being used for the single face paper that single face is printed, for the double faced paper of duplex printing) of the media type coupling setting of record installation etc.
Especially, except determine whether to provide the image of expection on one or two face of the medium of installing, the print media inspection can determine also whether the medium of installing is compatible with the printing model of preliminary election.Then can determine whether with such compatibility to start and/or forbid one or more printer function, for example by the printing of the first and/or second thermal printer head.
In a further embodiment, one or more medium sensors can be installed on two faces of each thermal printer head 50 and 60 (for example upstream and downstream), no matter to allow Print direction (for example forward and/or backward feeding medium direction) how all can respond to.
In addition, in other embodiments, can respond to hot print on first (front) and two faces of second (back side) medium face with single-sensor.When the contrast of comparing hot print with the background of blank print media is very high, and/or in the situation that on one or more induction wavelength print media transparent at least in part, such design is particularly useful.

As further shown in Figure 5, printer 200 may further include for pivotable support arm or covers 300 spring 350, open with controlled speed so that cover 300, thereby and for example avoid accelerating to be applied to the controllably closed of lid 300 that the power on 300 of covering brings by gravity.Can provide further sensor 360 detecting paper slip spare, and produce and can be used to forbid the signal of printing, notice POS operator (not shown) goes to replace and supplies with volume 260 etc.Also can provide sensor 360 to be used for the zone of the medium of printing with identification, comprise that identification comprises the zone of induced indicia or other pre-printed material.
As shown in Figure 5, printer 200 also can comprise the control electronic device for the operation of controlling printer 200.Control electronic device and can comprise motherboard 390, microprocessor or CPU90 and memory 80, memory 80 comprises one or more DRAM and/or NVRAM print buffer memory component.Printer 200 may further include communication controler 396, be used for communicating by letter with for example one or more main frames or the accessory system of POS terminal (not shown), this main frame or accessory system are used for to printer 200 input data with from printer 200 output data.Communication controler 396 can be supported USB, Ethernet and/or radio communication (for example 802.11,802.15 and IR) and other.The data that are used for printing are provided by communication controler 396 by the main frame POS terminal (not shown) of communicating by letter with printer 200 usually.The supplementary data that is used for printing, for example product and/or discount certificate information also can be provided by for example webserver (not shown), and this webserver uses communication controler 396 directly data to be provided or indirectly to provide data to printer 200 by main frame POS terminal to printer 200.The supplementary data of be used for printing can be detailed according to the commodity of selling or service, stock, chain scope or manufacturer, client's identity and/or one or more other transaction aspects change.
The memory 80 of two-sided direct heat printer 200 can have predetermined print data storage area to store the one or more predetermined print data piece on one or two face that will repeatedly be printed on print media.Predetermined print data piece can comprise such as storage identifier, sign, reward voucher, advertisement etc.Predetermined print data can with the data of being submitted to by the application software that is associated with POS terminal (not shown) together be printed to identical or different medium face.In the situation that during a plurality of data blocks are stored in predetermined print data storage area, can be by using hardware or software switch 70 to select to be used for the piece of printing, this can be printed on the position on medium or the face of the medium that is printed etc.
Two-sided direct heat printer 200 as above can be used for the traditional of single face direct heat printer for example or other application program operates by exploitation.In this case, two-sided logic OR mechanical printing functional switch 70 can be used from the input of single face application software and start the Double-side hot medium printing.
In response to the command messages or escapement sequence or the configuration setting by driver or functional interface as above that manually arrange or send to by communication controler 396 printer 200, switch 70 can start activation and the deactivation of one or more double side printing function.In an example, the single face application software is controlled at the printing of the submission data on the medium face usually, and switch 70 starts for example printing of the additional information on the relative medium face.This function allows before investment customizing print model application or other new application program or interface software or need not invest these and just can use traditional software to realize the advantage of two-sided direct heat printer.
The direct heat that the single face print application can thereby be controlled on a face of medium paper is printed, and double side printing function switch 70 is arranged to the hot print that is enabled on another medium face.The data of printing under the control of functional switch 70 can be to be stored in the data block that is used for as mentioned above duplicate printing in the memory 80 of printer 200.The data block that is printed can be for example by order or escape message and select, as the function of the data that receive from the single face print application, these data are for example the trade detail data, the data block that perhaps will be printed can be selected as mentioned above at random.
By the printing on a face that is enabled in the medium paper by the single face print application, and the printing of operation start on the opposite face of paper by functional switch 70, thereby can simplify demand for application software, wherein functional switch 70 activates and deactivates one or more two-sided direct heat printing functions.The all two-sided direct heat printing function of direct control is not used for tradition that single face prints or other application software thereby can be used for printing on a face of medium paper.Other data storage or that received by printer 200 or printer 200 can with other data can be printed on the opposite face of paper media.
In another example, the print data that two-sided direct heat printer 200 can be operated so that traditional or other application software are provided is printed on two faces of medium paper.In this case, two-sided logic OR mechanical printing functional switch 70 is used for starting the further operator scheme of sided thermal printer 200 with the data of dividing and distribution receives from the single face application software on two medium faces.Such division can be balanced, namely print a half data on each medium face, can be perhaps be allocated for consider pre-printed the medium of material or had the side information that will print to together with the data that the single face application program provides on medium etc. the use of medium is maximized.
As further option, sided thermal printer 200 can be designed as that comprise can be in the front and back of thermal medium or the function of printing on one side in office independently.
The example that Fig. 6 schematically shows the two-sided direct heat receipt printer 200 of Fig. 4 and Fig. 5 partly drives or the gear planar elevation view, and its middle cover 300 is in the close position.As shown in the figure, cylinder 220 with are connected respectively by the first gear 400 be connected gear 410 and connect in its end and be used for rotation.The first gear 400 operationally contacts with the second gear 410 and the 3rd gear 415.The 3rd gear 415 is connected to for driving the first and second gears 400 and 410 and their cylinders 220 separately and 280 motor 416.As shown in the figure, when being rotated in the clockwise direction by motor 416, the 3rd gear 415 drives the first and second gears 400 and 410 and their cylinders 220 and 280 separately, thereby print media is left with direction of feed guiding forward from printing volume 260 on each printhead.Similarly, when being rotated in the counterclockwise direction by motor 416, the 3rd gear 415 drives the first and second gears 400 and 410 and their cylinders 220 and 280 separately, thus print media on printhead with direction of feed backward or recall direction and be directed toward and print volume 260.Yet, optional motor and gear relation, and drive unit (such as belt drives, directly driving, friction-driven etc.), and rotation is possible.
The printer 200 of Fig. 6 also comprises one or more extra sensors, and one or more limit switches 420 for example, this sensor are provided for the signal of the state of the signal of control operation or printer 200.For example, the signal from the first limit switch 420 can be used in the lid 300 of notice POS operator printer 200 less than suitably closed.Similarly, can be used in from the signal of the first limit switch 420 and allow the automatic deactivation of printing, until cover 300 positions that are in suitable closure.Similarly, can be used in from the signal of the second limit switch 420 and combined to guarantee covering 300 by correctly closed from the signal of the first limit switch 420.This can comprise determines that cover 300 is suitably alignd with respect to pedestal 240, thereby before printing, the width that relative printhead (210 and 270) and cylinder (280 and 220) cross them contacts etc. fully and balancedly.
In addition, the signal from further sensor (not shown) can be used to indicate at the suitable pressure that has relatively obtained between printhead and cylinder for printing.Similarly, further sensor (not shown) can be used to indicate and obtain suitable tension force on print media, and perhaps for example the locking mechanism of one or more pallets 430 is suitably engaged.As for limit switch 420, the notice that can be used for triggering to operator (not shown) inappropriate condition from the signal of any such sensor, for example by sending error message to POS terminal (not shown), and/or by forbidding some or all of printer operation until condition be corrected etc.
For example the locking mechanism of one or more pallets 430 also is arranged on printer 200, with with pivotable support arm 300 fix in position, and keep the suitable location of relative printhead (210 and 270), cylinder (220 and 280) and deflector roll (230 and 290), comprise the suitable contact of keeping the width that crosses medium, and/or in printer operation along the feeding medium path tension force of 250 medium.As shown in the figure, pallet 430, and is discharged by pressing of button 435 on link stopper 434 by spring 430 against.Except pallet 430 is moved out from link stopper 434, button 435 by be pressed in cover apply on 300 enough upward forces with according to the contact that applies and frictional force with printhead from roller separation, freely opened thereby allow to cover 300.
If pivotable support arm or cover 300 and be opened and fall, the combination of pallet 430 and spring 350 has prevented that also pivotable support arm 300 from clashing into support arm or base constructions 240, or other parts of the printer 200 of printhead 210, cylinder 220 and/or deflector roll 230 for example.

The sided thermal printer print head configuration
Assembled automation or replace automatically feeding medium (for example replacing the automation feeding of hot paper roll or fanfold paper heap), for example ATM and various other self-aided terminal, for example the sided thermal printer of the printer 440 of Figure 10 has in line or printhead 450 and 460 that become a plane basically usually.In the retail application with the feeding of manual replacement coil paper, for example the sided thermal printer of the printer 200 of Fig. 5 can have relative to each other angled printhead 210 and 270, for example becomes the angle of general 90 degree to withdraw from the top that for example allows receipt.The angled directed spacing that reduces that allows between printhead 210 and 270 like this is used for making once minimizing by the not print area on the opposite face of direct heat print processing at medium or the length of blank space.Printhead can use and the needs of specified print media and/or printing environment (such as information kiosk printer, pharmacy printer, POS printer etc.) and change based on typewriter terminal with respect to suitable direction, orientation and the position of another and/or their minute other cylinders.
The printhead spacing of optimizing
The horizontal spacing of the first and second thermal printer heads (for example spacing 55 of Fig. 1) can be optimized to allow scattered fully by the heat that the first printhead is applied on the first surface of two sides image-forming component, does not cause the printing of not expecting on first surface thereby be applied to heat on second of image-forming component by the second printhead.The function of the attribute of any coating of utilizing in the image-forming component that optimize spacing and be the image forming material and/or the dyestuff that utilize in the amount, image-forming component of the heat that is applied by each printhead, comprises coating layer thickness and heat conductivity, the attribute that comprises any substrate that utilizes in the image-forming component of substrate thickness and heat conductivity, print speed etc.
The configuration of sided thermal printer deflector roll
Sided thermal printer 200 or 400 can comprise be used to the suitable tension force of keeping print media and the boot media a pair of deflector roll 230 and 290 by printer.Deflector roll can be connected the relative arm with pivot rotational support printhead and cylinder respectively.For example, printhead, cylinder and deflector roll can be connected to support arm or the base construction on the face in feeding medium path.Relative printhead, cylinder and deflector roll element can be connected to the second support arm, and for example with respect to the pivotally supported structure of base construction, the second support arm aligns on the opposite face in feeding medium path.Thereby each printhead can make relatively by cylinder, and deflector roll can to stride across the feeding medium path relative with another deflector roll or adjacent.The one or more springs that make printhead prop up cylinder can keep propping up the contact of print media.Similarly, can spring loaded one or two deflector roll to keep the suitable deflector roll contact with print media.But in arrangement, two printheads can stride across the feeding path and not need cylinder and directly relative to each other.In such configuration, each in two support arms can be connected to deflector roll and printhead that is associated.In another configuration, deflector roll can comprise the deflector roll of a pair of isolated co-axially align.Distance between the deflector roll of co-axially align allow to increase the medium that the variable-size paper guides to hold different in width, no matter medium is volume, folding, paper or other continuously.
The cylinder configuration
In the two-sided direct heat printer 200 of printer for example shown in Figure 5 200, cylinder 220 and 280 can have basically round cross section.Similarly, in optional embodiment, cylinder 220 and 280 can have the cross section of square basically or rectangle, or for arbitrary in printhead 210 and 270 or both, presents basically flat surface.Further, no matter profile how, each cylinder 220 and 280 can be substantially the same size and/or have substantially the same cross-sectional profile and/or zone, and perhaps cylinder can be different aspect one or more with respect to another, is included in the length aspect different.
According to separately design and/or use, one or more cylinders or cylinder surface can comprise one or more coatings or material.For example, when cylinder was used for by printer feeding medium, for example for the cylinder 220 and 280 of Fig. 5, cylinder and/or its surface can comprise for example material that enhancing frictional force is provided of rubber.Similarly, when cylinder comprised flat paper type surperficial, cylinder can comprise or coatedly have a for example material of the frictional force that reduction is provided of polytetrafluoroethylene (PTFE) (PTEE).
In one embodiment, cylinder has the cross section of basically justifying of about 3/8 to 1/2 inch diameter, and basically has equal length.
In another embodiment, two thermal printer heads stride across the feeding medium path and relative to each other basically, and as each other each cylinder.In this case, one or two thermal printer head can comprise or coatedly have frictional force and reduce material.
Driving mechanism
In two-sided direct heat printer, can provide feeding medium by one or more belts, wheel, roller etc.In an example, as shown in Figure 6, the driven roller with cylinder 220 and 280 forms on the opposite face in feeding medium path 250 is connected for being rotated by gear.Alternatively, any in two cylinders can united ground connect or driven independently by following parts, these parts are (1) one or more belts or band except other things, (2) two or more meshing gears, (3) one or more direct drivings, and/or (4) one or more direct contact friction elements, arbitrary in these parts or all operationally contact or directly driven by one or more CD-ROM drive motors or actuator with one or more CD-ROM drive motors or actuator.
Similarly, can provide the upstream and downstream drum drive, the upstream and downstream cylinder that drives of motor for example, this driving mechanism can carry out operation separately or synchronous.Advantageously, when being desirably in forward direction mobile imaging element, provide power driving downstream roller, and when expecting in the opposite direction the mobile imaging medium, provide power with the driving upstream roller.Two driving feed mechanisms allow automatically recalling of image-forming components, thereby it is first-class to print the part that can occur in element, and this part is the part that otherwise will can not be used due to the skew in the spacing 55 of printhead in the printer of two sides etc.Automatically recall feature and also can drive two cylinders by single-motor and realize etc., for example when by as Fig. 6 with are connected as shown in one or more belts or two or more gear when jointly connecting cylinder and being used for rotation.
Balanced printhead contact
Can provide the printhead of equilibrium of the width that strides across the two sides image-forming component to the contact of cylinder in the printer operation process.The mechanism that is used for this can be included on printhead, cylinder and/or common holder or and their one or more springs of being associated, spring 320 shown in Figure 5,330 and/or 350 for example, the attachment 600 of loading spring shown in Figure 12 etc.
The printer operation license
For example with one or more sensors 100 of one or more paper sensor forms, 360 and 420 exist and/or electronic device is controlled in thereon printing for detection of medium, can be used to allow operation and/or the sided thermal printer function of (for example as allowing) and control sided thermal printer for detection of the suitable mechanical arrangement of the type element that is used for printing and the contact-making switch of alignment etc.For example, can provide one or more printheads with when the first and second printheads are properly positioned with respect to the first and second cylinders, reach suitable contact between the first and second printheads and their cylinders separately and/or suitably fixed and only allow printer operation when supporting pivotable arm configuration or covering 300 etc.Similarly, can provide one or more optical pickocffs to detect the existing and printing on print media of print media, be used for starting and being controlled at the position of the hot print on medium.
Revocable printing mechanism
Can provide one or two printhead and/or the cylinder that a kind of mechanism (not shown) recalls the two sides printer with being used for each also to make simultaneously the function of the minimise wear on untapped printhead or cylinder with the permission printer in the operation of single face printing model.Evacuating mechanism can be by manually or automatically, electricity ground or motor ground actuating.
Printer function
Be used for the two-sided thermal print machine of printing on the two sides and can advantageously support following function with the firmware that is associated:
1. single face printing model.The basic single face of this printing model support is printed, and allows the operation of thermal printer head on the one side in feeding medium path.
2. the duplexmode (for example printing model of buffering) that has the single face order.This printing model can allow before image forming medium by the some or all of print data of printer storage.The print data that receives from for example POS terminal (not shown) is stored in print buffer 80 until receive for example closing the transaction message of cutting knife (cutting) order.When receiving the cutting knife order, firmware can be divided the print data of buffering and for example specify that the first of the first half data is used for printing on first (just) face of medium, and specifies the second portion of the data that for example remain half to be used for printing on second (instead) face of medium.The data of appointment be printed to each first surface and second upper after, can carry out physics cutting knife cutting that the blade mechanisms 370 by the volume medium carries out, to the end of paper media advance to etc., thereby complete print out task.Can by send to printer 1F 11 for example * * escape code of order or order be by manually arranging the printing model that one or more DIP or other switch or jumper start two-sided buffering with the diagnosis setting program.
3. the duplexmode (for example using controlled printing model) that has two-sided order.This printing model allows the application program controlling double side printing function by the transaction software of for example moving on the POS terminal.Such application can by be controlled at receipt for example first (for example, printing is controlled in the position of the print data on just) and the second (for example, anti-) face, when controls the print application data and with what order print application data etc.Two-sided command mode can be used print data at one or more buffers or other memory location stores before printing.Similarly, can from one or more buffers or other memory location select tentation data with have or do not have use print data one or more positions of one or two face of medium print.Can start two-sided command mode by the reception by one or more duplex printing orders, diagnostic program etc. that manually arranges of switch or jumper.
4. the duplex printing pattern that has tentation data.When in this pattern operation, tentation data from one or more predetermined print data storage facilities (for example buffer or other memory location) can be printed on a face of two sides thermal medium, and for example the application data of POS terminal transaction information can be printed on the another side that separates with the tentation data printing surface.When having selected this pattern, printer can be enabled in the printing on two faces of medium, or print data is used in storage in data storage facility 80, until receive for the order that starts duplex printing.Manual setting that can be by switch or jumper, by reception by one or more orders that are associated etc. starts the duplex printing pattern with tentation data with diagnostic program.
Printer capabilities
Sided thermal printer 200 preferably has following ability:
Print speed: 4.0 inches per seconds (IPS) when 55 watts of power is provided.This comprises the front and back printing.
Print speed: 6.7 inches per seconds (IPS) when 75 watts of power is provided.This comprises the front and back printing.
Print buffering: suppose 44 characters per line sign/text storage, with 7.5 row per inch (LPI) up to 450 print lines.
Preferred default restriction
When printing, preferably, character attibute is identical for the front and back of receipt.If for example print in front print two high (double high), printing overleaf is also two high.Yet optionally just/back side character boundary and/or font are possible.
When the printing model of two-sided buffering is printed and has been surpassed the capacity of print buffer 80, then can distribute on every of the medium data of buffering that be used for to print of printer are carried out before the cutting knife cutting on the one side in the front of for example receipt and are printed remaining data.Alternatively, printer can distribute and print the data of buffering at two faces, then fill print buffer 80 with other print data, and continues this processing until receive for example closing the transaction message of cutting knife cutting order.
