Description
Technical field
Present invention is directed at thermal printing, more particularly, be directed to the thermal media controlled in printer and the Exposure between feed roller.
Background technology
In dye diffusion heat transfer printer, well-known convention is, in order controllably to drive paper and to maintain image registration at color between inferior, conventionally uses and executes loaded pairing hold-down roller through the driven roller of invasive veining and between paper and driven roller.The drive system of this type is only being printed or is being carried out when single work is printed on printing paper, not causing any image artifacts in one side because through the driven roller of invasive veining do not contact paper through printing surface.The method is printing two-sided or carrying out when duplex is printed really presenting problem, because must contact two faces through print paper through the driven roller of invasive veining.For two-sided or duplexing printing, can be compromised because the described surface through invasive veining becomes with the paper surface of the Surface Contact through invasive veining of driven roller.This paper surface through infringement may not so easily receive dyestuff and shift, thereby causes region that once going through of paper contact with the invasive texture of driven roller and the visible density variation not contacting between the region of described invasive texture.
In dye diffusion shifts printer firmware, being incorporated to the backoff algorithm of proofreading and correct across page variable density and/or reduction page variable density is also common convention.In printer hardware or printer firmware, can there is restriction, the print artifact that backoff algorithm cannot full remuneration be produced by driven roller.Due to these restrictions, be minimized in through there is the new number of times contacting between the driven roller of invasive veining and paper surface and become more important.
About Fig. 2 to 3, shift and print for two-sided or duplexing dye diffusion, a kind of common methods is to use two thermal printing heads 117 as show in Figure 2, 137, via driven roller (or feed roller) 113 and hold-down roller 112, web-like printing paper 110 is driven between air roll 123 and a thermal printing head 117 (below claiming TPH1), on a face of printing paper 100, print, then by making feed roller 113 reversings reorientate paper, and printing paper is driven between air roll 131 and the second thermal printing head 137 (below claiming TPH2) via driven roller 113 and hold-down roller 141 as demonstrated in Figure 3 and printing paper without print surface 101 on printing.The paper position that sensor 124 and 130 detects in printer.After printing on two surfaces 100,101 that complete printing paper, discharge and conventionally after being cut by cutter 126, collect via paper delivery guide member 125 and output to via roller 127 paper through printing paper along path 121 or 133 from printer and catch pallet 128.
With reference to figure 4, it illustrates by driven roller 113 and hold-down roller 141 and drives the paper of a length, thereby paper surface 100 is suffered and the contacting of the invasive superficial makings of driven roller, thereby infringement is for the paper surface 100 of follow-up printing.In in view of the common expected not preferred Method of printing of above printing step sequence, to again release next duplex printing operation with use thermal printing head TPH1 on paper 100, to print (referring to Fig. 7) and then reorientate paper and by paper be driven into another thermal printing head TPH2 and printing paper 101 without printing surface on print, therefore repeat Fig. 2,3 and 4 step.This prints sequence introducing paper and back translates into unnecessary the reorientating between the face 100 of TPH1 117 and paper at the face 101 of TPH2 137 and paper, thereby unnecessarily make again paper surface during retracting, suffer and the contacting of the invasive superficial makings of driven roller, thereby damaged paper surface.
Print about photo book, in Fig. 8, illustrate in order to generation order content of pages and view data sent to printer to make photo book be the known method of printing with appropriate page order, wherein host computer 10 is delivered to host request through connecting printer 50 and receiving printer response.This is that host computer is conventionally by USB connection, wired ethernet or wireless connections and common methods through being connected printer communication.Fig. 9 shows the typical print job printer page sequence that sends to printer from host computer: the page 10 951, the page 9 950, the page 8 941, the page 7 940, the page 6 931, the page 5 930, the page 4 921, the page 3 920, the page 2 911, the page 1 910.The described page sends to printer taking reverse order order and makes to be discharged to the page of printing the last printing in catcher pallet 128 as the first page of photo book.Sequence (contrary) is printed in the typical print job substituting: the page 1, the page 2, the page 3, the page 4, the page 5, the page 6, the page 7, the page 8, the page 9, the page 10.This page order is what face down by causing photo book printing in catcher pallet, but will be appropriate page order.

For creating two-sided or duplexing photo book, the preferred Method of printing above summarized is for reducing between the photo book startup stage on dye diffusion heat transfer printer image artifacts as crucial and also produce through improved handling capacity.But, implementing when this preferred Method of printing, must amendment page print sequence in case produce from by printer output to the sequentially paging photo book through print paper assembling paper delivery pallet.
The typical print job above discussed is printed sequence and is suitable for supporting for each print job first printing surface A and not preferred method of printing surface B on TPH2 then on TPH1 all the time.If any one in these sequences is for being used the preferred Method of printing (wherein every next duplex printing is first to print with on the identical thermal printing head of finally printing in the time previously printing and paper) of two printheads, photo page face order will be for incorrect so.Preferably Method of printing needs the following order of printing: new print paper, the page 10 951 (TPH1), the page 9 950 (TPH2); New print paper, the page 7 940 (TPH2), the page 8 941 (TPH1); New print paper, the page 6 931 (TPH1), the page 5930 (TPH2); New print paper, the page 3 920 (TPH2), the page 4 921 (TPH1); New print paper, the page 2911 (TPH1), the page 1 910 (TPH2), this produces with identical paper sheet stacking demonstrated in Figure 9 and arranges in paper delivery pallet.This page order causes being discharged to being the first paper of photo book and being therefore correct through completing the stacking page order that faces up of printing finally by print paper in printing catcher pallet.It should be noted that TPH2 prints the stacking all pages that face up of printing in this sequence and the therefore prints odd numbering page.
Sequence is printed in the preferred print job substituting: the page 1 (TPH1), the page 2 (TPH2), the page 4 (TPH2), the page 3 (TPH1), the page 5 (TPH1), the page 6 (TPH2), the page 8 (TPH2), the page 7 (TPH1), the page 9 (TPH1), the page 10 (TPH2), this is what face down by causing photo book printing in catcher stackable pallet, but will be appropriate page order.In this case, the TPH1 prints odd numbering page.
When print job contain odd number for print duplexing paper time (as at these examples discussed so far), it is more complicated that sequencing becomes, because must change the printing sequence of next print job and could utilize the method for optimizing of embodiments of the invention.In example demonstrated in Figure 9, stacking for the printing facing up, the face of finally printing is the page 1 910 of printing on TPH2, face B.Therefore,, in order to continue with method for optimizing for next print job, next page to be printed (its first page that is next print job) should reuse TPH2 and print on face B.It should be noted that this is different from the first page of printing of previous print job (it has used TPH1 for face A).Stacking for the printing facing up, sequence is printed in the print job of this next photo book: the page 9 (TPH2), the page 10 (TPH1), the page 8 (TPH1), the page 7 (TPH2), the page 5 (TPH2), the page 6 (TPH1), the page 4 (TPH1), the page 3 (TPH2), the page 1 (TPH2), the page 2 (TPH1).It is different that sequence is printed in each print job, and this depends in previously print job and has finally used which face and head.
Similarly, if be next one side (single work) print job in print queue, be on the thermal printing head identical with the last page of previous print job and paper, to print all single work printed matters in order to minimize roller artifact that printer produces and the method for optimizing of maximize throughput so.Which print job printing sequence this can affect is applied to next duplexing print job, and this depends on last which face and the head of having used.In the time using the preferred Method of printing of the driven roller artifact in order to minimize printer generation, can there is additional complexity.If there is plug paper during printing, lack medium situation or other problem, may become incorrect for the logic of page sequencing so.This can remove paper and restart print job.
For relating to host computer in the solution that maintains appropriate photo page face order when starting preferred Method of printing that each duplex prints on the last identical face of printing for previous printing and inquire about to determine to printer which face (the face A on TPH1 or the face B on TPH2) that is ready to start will release when next is printed paper at it using.Then, host PC can produce view data and send described view data based on will first printing which face with exact sequence.This solution solves fully by the odd number paper in print job, single work and prints the complexity proposing and also solve the additional complexity being caused by plug paper or other printer error.
With reference to Figure 10, now by communicating by letter between the printer of print system illustrated in description host computer and formation Fig. 1.At step 171 place, there is the host computer 10 of intraware as described above and receive data (view data of for example coming from input source) and store described data from input data source via (for instance) USB2.0 communication protocol.At step 172 place, carry out internal data processing by host computer, wherein software is obtained received view data and described view data is carried out to some task, for example colour correction.At step 173 place, view data moves to the printer processes stage from internal image data processing.At step 173 place, treated view data is sent to printer from host computer.This can for example, complete by various means (USB2.0 communication protocol).Pictorial data representation from host computer to printer can be stored in the page that is preferred sequence in the frame buffer of printer.Once frame buffer is cleared, it just can accept the more multilevel image data from host computer.USB2.0 communication protocol allows the constant communication between main frame and printer.
Figure 11 illustrates the flow chart of printing sequence according to a preferred embodiment of the invention, and wherein host PC is made response to printer inquiry and printer to host PC.Step 200 representation class is similar to the main frame of step 173 of Figure 10 to printer data processing capacity.At step 201 place, always extract view data from latter two page of the residue print job of main frame internal data processing.Then,, at step 202 place, host computer is inquired about to printer for the printing paper position in printer.At step 203 place, inquiry/communication is transmitted into printer from host computer, and at step 204 place, printer is made response with printing paper position to host computer.Step 205 represents to be branched off into thermal printing head 1 (TPH1) or the decision point of thermal printing head 2 (TPH2).If printer use sensor 124 130 or both and to return paper position be to be positioned in the side of thermal printing head 1 (this also mean paper due to the straight paper path of leading to TPH1 and crossed by paper when by described paper feed forward physically near TPH1), paper surface face A (step 206) be by the surface of printing thereon so.Then, at step 207 place, suitable view data is sent to printer by host computer, and in this example, described suitable view data is from the first view data in the sequence of pair of pages face print job at step 208 place.At step 209 place, the paper position of printer is switched to the side of thermal printing head 2.At step 211 place, will carry out printing paper surface face B from the view data of the second view data in the sequence of pair of pages face print job by thermal printing head 2 use.
If step 205 place printer use sensor 124 130 or both to return paper position be to be positioned in the side of thermal printing head 2, the paper of step 212 surface face B is the surface of printing thereon so.At step 213 place, suitable view data is sent to printer by host computer, and described suitable view data is from the second view data in the sequence of pair of pages face print job, as shown in step 214 place.At step 215 place, the paper position of printer is switched to the side of thermal printing head 1.Paper surface face A216 is by the surface of printing for 1 time at thermal printing head.At step 217 place, send suitable view data from the print job of pair of pages face, i.e. the first view data.At step 218 place, another decision point is based on whether needing to print more multilevel image data.If so, algorithm turns back to two extra page or the last page of host computer in step 201 place extraction view data so.If not, complete so print job.
For being to make host computer inform that printer is intended to print on which face at paper each group view data using in the alternative solution that maintains appropriate photo page face order when starting preferred Method of printing that each duplex prints on the last identical face of printing for previous printing.For instance, printing or view data are identified as to face A and face B.But printer can be determined and next will use which view data based on no matter being about to print which face (the face A on TPH1 or the face B on TPH2).
With reference to the Figure 12 that illustrates this alternative, step 301 representation class is similar to the main frame of the step 173 in Figure 10 to printer data processing capacity.At step 302 place, host computer sends the order of the view data of reception or will on which face of paper, print which view data to printer.At step 303 place, the view data of the face A for paper is sent to printer by host computer.At step 304 place, the view data of the face B for paper is sent to printer by host computer.To understand, just described two steps can be carried out by reverse order.At step 305 place, printer with sensor 124 130 or both detect and identify the position of paper in printer.Step 306 is that this depends on where paper is arranged in printer to using thermal printing head 1 or the decision point of thermal printing head 2.If it is to be positioned in the side of thermal printing head 1 that printer is determined paper position, at step 307 place, paper surfaces A is defined as so to the surface of printing thereon.At step 308 place, printer access is for the view data of face A.At step 309 place, print suitable view data from the print job of pair of pages face, face A.At step 310 place, printer is switched to paper position the side of thermal printing head 2.At 311 places, paper surface B is by the surface of printing for 2 times at thermal printing head.At step 312 place, to print suitable view data from the sequence of pair of pages face print job, face B.If determine that at step 306 place printer paper position is to be positioned in the side of thermal printing head 2, paper surface B314 is next by the surface of printing so.At step 313 place, printer access correspondence image.At step 315 place, to print suitable view data from the sequence of pair of pages face print job.At step 316 place, the paper position of printer is switched to the side of thermal printing head 1.317 represent paper surfaces A, and it is by the surface of printing for 1 time at thermal printing head.At step 318 place, print suitable view data.Step 319 represents based on whether needing to print the more decision point of multilevel image data.If so, algorithm logic turns back to host computer at two extra page or the last pages of step 302 place acquisition view data and carries out face identification so.If not, complete so print job.
This solution solves fully by the odd number paper in print job, single work and prints the complexity proposing and also solve the additional complexity being caused by plug paper or other printer error.The benefit that this solution surpasses previous solution is, host PC can continue to send view data with nature or reverse order order, and nonessentially depends on print destination and change sequence.
