As embodiment, the operational instances of basis based on the print system of the embodiment of said structure is described below.

(first embodiment)

The summary that comprises based on the operation of the print system of the DSC 3012 of said structure and PD printer 1000 is described below.In the print system according to first embodiment, DSC 3012 and PD printer 1000 can be according to DPS (directly print system) standard operations.

The chart of Fig. 6 is used for illustrating the print system according to first embodiment, when the sequence of DSC3012 when PD printer 1000 sends the print request that prints.

This processing sequence is carried out when PD printer 1000 and DSC 3012 couple together by cable 5000, and has confirmed that it meets the DPS standard.DSC 3012 sends the state (600) of " ConfigurePrintService " (configuring print service) to obtain PD printer 1000 to PD printer 1000.In response, PD printer 1000 is to the current state (being " free time " state in this example) (601) of DSC 3012 notice PD printers 1000.The processing power (602) of DSC 3012 inquiry PD printers 1000, and send the printing corresponding with this processing power and begin request (StartJob, beginning task) (603).Sending the precondition that this printing begins to ask is in 601, is " very " from " newjobOK (new task is ready) " (Fig. 8 B) in the status information (will be described later) of PD printer 1000.

Respond this printing and begin request, PD printer 1000 is based on the fileinfo (604) of the file ID request DSC 3012 of the view data that will print.In response, DSC 3012 transmits fileinfo.Fileinfo comprises such as file size (file size), has or not information projects such as thumbnail and file attribute.When PD printer 1000 receives fileinfo, and judge when this document can be processed the file (605) of PD printer 1000 request DSC 3012.DSC 3012 gives DSC 3012 with the image data transmission of requested file.Then, when PD printer 1000 beginning print processing, on behalf of the status information of " printing ", PD printer 1000 will send to DSC 3012 by " NotifyDeviceStatus " (announcement apparatus state) in 606.After the print processing of one page finished, PD printer 1000 was given DSC 3012 with " NotifyJobStatus " (notice task status) 607 with the end notification of this print processing during one page under beginning to handle.For the printing of having only one page, PD printer 1000 finish to print when being requested page with " NotifyDeviceStatus " (announcement apparatus state) 608 will " free time " state notifying to DSC 3012.Print for the N unification of on one page, arranging several (the N width of cloth) images and printing, PD printer 1000 when every printings N width of cloth image to DSC 3012 transmission " NotifyJobStatus (notice task statuses) " 607.The order of obtaining of sending timing and view data of " NotifyJobStatus " among first embodiment and " NotifyDeviceStatus " all is for example, depends on product specification, can expect various situations.

Print processing comprises such a case: the printing that the file ID of the view data that print is comprised in from DSC 3012 begins also to be transmitted simultaneously therein to carry out printing in the request (StartJob).Print processing also comprises such a case: begin request in the printing from DSC 3012 and only comprise the file ID that is used in the DPOF file of common photo in developing and printing in (StartJob), and be transmitted to PD printer 1000, PD printer 1000 is explained the DPOF file, obtain the file ID of necessary image data, and print.

Fig. 7 is used to illustrate that DSC 3012 issues the example that the printing of PD printer 1000 begins to ask.

The configuration (jobConfig) of Reference numeral 720 expression print out task in Fig. 7, Reference numeral 721 expression type informations (printInfo).

The following describes configuration 720.Reference numeral 700 (quality, quality) is specified print quality, such as " common " or " high-quality ".Reference numeral 701 (paperSize, paper size) designated paper size, Reference numeral 702 (paperType, paper type) designated paper type is such as " common paper ", " printing paper " or " Alhue paper ".Reference numeral 703 (fileType, file type) is specified the type of the image file that will print, when for example using DPOF, specifies the type of representing DPOF by file type 703.Whether Reference numeral 704 (datePrint, date print) specifies date printed.Whether Reference numeral 705 (fileNamePrint, filename print) specifies the print file name.Whether Reference numeral 706 (imageOptimize, image optimization) is specified and image is optimized.Reference numeral 707 (fixedSize, fixed measure) specifies whether carry out the fixed measure printing.Whether Reference numeral 708 (cropping, prune) specifies the specified scope of print image.

Type information 721 include file ID 709 (fileId) and date and time information 710 (date).

Fig. 8 A and 8B are used for the information project that explanation comprises at above-mentioned JobStatus (task status) and DeviceStatus (equipment state).JobStatus (Fig. 8 A) and DeviceStatus (Fig. 8 B) are sent to DSC 3012 from PD printer 1000.DSC 3012 can ask PD printer 1000 to send these information projects according to arbitrary timing.

In Fig. 8 A, when specifying printing DPOF file, " prtPID ", " ImagePath " and " copyID " becomes effectively." prtPID " is the identification information (ID) by the printing portion of DPOF file appointment." ImagePath " is the information of appointment by the path of the image file of DPOF file appointment.When specifying many parts of copies of printing, " copyID " specifies the quantity of copy when printing.In the printing based on the DPOF file, DSC 3012 begins to describe in the request (StartJob) " fileID (file ID) " of DPOF file in printing, and this printing is begun to ask to send to PD printer 1000.In response, PD printer 1000 can begin the printing of this DPOF file.PD printer 1000 obtains the DPOF file based on " fileID " of DPOF file, carries out " GetFileID (obtaining file ID) ", specifies in " fileID " of the fixed image file of DPOF document.The image file of PD printer 1000 request DSC 3012 obtains view data.As a result, can be printed on the fixed image of DPOF document.Carrying out based on the DPOF file in the process of printing, PD printer 1000 usefulness " NotifyJobStatus " are notified " prtPID " to DSC3012, " ImagePath " and " copyID " that represent print progress.

In the print procedure of DPOF file since any former thereby interrupt after, when restarting print processing, print processing is restarted from the top of the page of print processing termination.

" progress (process) " represented in the middle of the number of pages of expection, the current page of printing (N/T), and wherein N represents current type face, the sum of the type face that the T representative will be printed.The quantity of the image that " imagePrinted " expression has been printed.

The following describes DeviceStatus (equipment state) (Fig. 8 B).

" dpsPrintServiceStatus " specifies the state of PD printer 1000, and sent to DSC 3012 from PD printer 1000." dpsPrintServiceStatus " comprises " free time ", " printing " and " time-out " state." jobEndReason (task termination reason) " points out the done state of print processing, and in the end the printing of page or leaf is transmitted to DSC 3012 when finishing." errorStatus (error status) " represents error status, and is transmitted when producing mistake." errorReason " representative produces wrong reason, and is transmitted with " errorStatus ".

" disconnectEnable (can disconnect) " can print even expression USB cable 5000 is connected page or leaf with 1000 disconnections of PD printer.PD printer 1000 is notified to DSC 3012 with " disconnectEnable ".The processing power of " capabilityChanged " expression PD printer 1000 changes, and is transmitted to DSC 3012." newJobOK " expression PD printer 1000 can be accepted print request, and is transmitted to DSC 3012.

The flowchart illustrations of Fig. 9 restart to handle according to the printing of the DSC 3012 of first embodiment.The program of carrying out this processing is stored among the ROM 301, and CPU3100 carries out control and treatment according to this program, to realize described processing.

In this was handled, in the implementation of print out task, for example when cable 5000 was disconnected, printing was ended.Afterwards, rebulid DPS and connect, specify the print button of DSC 3012, instruction PD printer 1000 restarts printing.PD printer 1000 restarts to print then.

This interruption of handling print processing among the interruption of print processing in the hypothesis PD printer 1000 and the DSC 3012 is by PD printer 1000 and DSC 3012 identifications.

At step S1, judge whether by stube cable 5000 grades DSC 3012 and PD printer 1000 physical connections, and set up DPS and reconnect.If set up connection, then process advances to step S2.Restart to print if DSC 3012 specifies, judge then whether print processing is interrupted.If print processing was not interrupted, then process advances to step S3, carries out normal print processing, such as the processing that newly begins print processing according to print command.

If print processing is interrupted, then process advances to step S4.Judge newly set up the PD printer 1000 that connects and the PD printer that has interrupted last print processing 1000 whether be same model (identical＜dpsVersion〉and＜productName (name of product))), whether whether be the model (＜productName 〉) of same manufacturer, perhaps be same supplier's model (＜vendorName〉(supplier's title)).In this handling procedure, determine the model of PD printer 1000 according to the content of sending from PD printer 1000 as the response of " ConfigurePrintService " that DSC 3012 is sent.When having reconnected identical PD printer, can not go wrong.Even printer for another kind of model, if the manufacturer of printer or supplier are identical,, also be possible according to the print processing again of first embodiment based on manufacturer or supplier's design, can determine to restart to print, process advances to treatment S 6 subsequently.If be "No" among the step S4, then process advances to step S5, judges that print processing can not continue, and show a piece of news on the display unit 2700 of DSC 3012.If necessary, can change the UI (user interface, custom menu window) that is presented on the display unit 2700.

If determined that at step S4 the equipment that reconnects is compatible model, then process advances to step S6, judges whether the execution of print processing has used the DPOF file.If the result of step S6 is a "Yes", then process advances to step S7, sends the file ID of DPOF file to PD printer 1000.In this example, above-mentioned " prtPID ", " ImagePath " and " copyID " is transmitted with the file ID of DPOF file, will use the DPOF file to restart the file of print processing thereby specify.

In step S6, if print processing is not to use the DPOF file to carry out, just each image file is wanted designated and is printed, and then the file ID of the image file except the image file of having printed is sent to PD printer 1000 simultaneously to carry out printing in the file ID of the image file that will print.Note, restart instruction, in the action button of DSC 3012, specify a print button,, restart print processing " StartJob " sent to PD printer 1000 from DSC 3012 as printing.

When beginning to descend one page, " jobStatus " (meaning is to begin to print down one page) that PD printer 1000 usefulness PD printers 1000 send given DSC 3012 with the end notification of each page printing, perhaps, for last page, notify with " jobEndReason " that comprised in " deviceStatus ".Therefore, DSC 3012 can confirm the quantity of print image.When one one width of cloth ground print image, whether the amount of images specified according to print command has been printed, perhaps, when printing processing based on the DPOF file, according to the process in the DPOF file (" prtPID ", " ImagePath " and " copyID ") or print processing whether finish, judge whether print processing is interrupted.

When printing piece image on one page, the number of printer paper is consistent with picture number.But when arranging on a piece of paper and printing several (the N width of cloth) images, the quantity of the image that print and the number of printer paper are inconsistent.DSC 3012 must make the number of printer paper and the quantity Matching of view data according to printing model.

(the 3rd embodiment)

The process flow diagram of Figure 10 is used for illustrating a kind of processing of the print system of third embodiment of the invention.

In the 3rd embodiment, when DSC 3012 sends any order to PD printer 1000, and the state of PD printer 1000 is when changing, PD printer 1000 usefulness above-mentioned " NotifyDeviceStatus " with state notifying to DSC 3012.But when the state of PD printer 1000 did not have change or operating lag, by the order of before having sent, DSC3012 judged that the state change of expection has taken place (estimation) in PD printer 1000, and the processing of execution correspondence.In order to confirm the state of PD printer 1000, DSC 3012 sends " GetDevicStatus " (obtaining equipment state) to PD printer 1000, obtains the state of PD printer 1000, and carries out the processing corresponding to the printer modes that is obtained.

An example below with reference to the such processing of the flowchart text of Figure 10.

At step S10, printing begins request " StartJob " and is sent to PD printer 1000.Process advances to step S11, judges whether to have received predetermined condition responsive " NotifyDeviceStatus " (announcement apparatus state) from PD printer 1000.If the product type of PD printer 1000 can only be accepted a print out task, then the expression PD printer 1000 of " NotifyDeviceStatus " newJobOK that can accept next print out task begins to should be " vacation " after the request " StartJob " sending to PD printer 1000 to print.If received normal response (newJobOK is " vacation ") at step S11, then process advances to step S12, and waiting n ewJobOK becomes " very ".Afterwards, carry out and to send Next Command or according to normal print processing from the request output image data of PD printer 1000 etc.

At step S13, judged whether to receive " NotExecuted " (not carrying out) that expression can not be carried out StartJob.If received " NotExecuted ", then process advances to step S20, sends " GetDeviceStatus " (obtaining equipment state) to PD printer 1000, obtains the current state of PD printer 1000.If this state has disclosed the reason that instruction can not be performed, then can retransmit " StartJob ", the message of representing this meaning is displayed on the UI (user interface) of display unit 2700 of DSC 3012.Afterwards, retransmit instruction if the user uses button 3103 to specify, then process advances to step S22 from step S21, retransmits " StartJob " instruction that is not performed to PD printer 1000.Do not specify if import repeating transmission at step S21, then process advances to step S19 from step S21.

If do not receive " NotExecuted " at step S13, then process advances to step S14, judges whether to have received " NotSupported " (not supporting).If received " NotSupported ", then process advances to step S15.In this case, PD printer 1000 is not supported " StartJob " that before sent, and for example, the project that is not supported (impossible appointment) is displayed on the UI of display unit 2700, and expression PD printer 1000 is not supported print command.

Do not support the implication of " StartJob " instruction to comprise that PD printer 1000 do not support the situation of " StartJob " instruction itself, also comprise such situation: PD printer 1000 is supported " StartJob " instruction itself, but, owing to specified unsupported paper size or paper type, therefore do not supported current " StartJob " instruction of sending.In this case, be similar to above-mentioned example, the UI of DSC 3012 is rebuild, so that can not select inappropriate antiquarian or paper type (will grasp the project of operation setting at printing).This can reduce when sending " StartJob " when instruction to PD printer 1000 once more, receives the possibility of " NotSupported " once more.Note, when receiving " NotSupported ", can carry out and for example confirm the paper size that PD printer 1000 is supported or the processing of paper type.

If do not receive " NotSupported " at step S14, then process advances to step S11 '.This step hypothesis response contents is " OK " (no problem) basically.If received predetermined condition responsive at step S11 ', then process advances to step S12, continues normal running.If do not receive predetermined status information at step S11 ', then process advances to step S16, judges whether to continue normal running.This can use above-mentioned UI to show, selects normal running to allow the user.If process forwards normal running to, then process advances to step S12.If the user does not import any instruction, process does not forward normal running to, and then process advances to step S17, uses the state of " GetDeviceStatus " request PD printer 1000.Process advances to step S18, and the state of PD printer 1000 is acquired, if this state is a normal state, then this state is judged as normal estimated state, and process advances to step S12.If obtained another state, then process advances to step S19, carries out the processing corresponding to the state that is obtained.

The reason that " NotExecuted " that why will not estimated at step S13 beams back in response for example is, PC3010 is connected to PD printer 1000, the time that is received by PD printer 1000 from the print command of PC3010 almost begins request simultaneously with printing from DSC 3012, has started the print processing from the print data of PC3010.Just, because " NotifyDeviceStatus " that DSC 3012 sends based on PD printer 1000 in advance thinks that " newJobOK "=" True " (very), DSC 3012 send " StartJob " order.But, just when sending " StartJob " order, be provided with " newJobOK "=" False " (vacation), in response, PD printer 1000 is beamed back " NotExecuted ".Think like this, " newJobOK "=DSC 3012 of " True " received the response " NotExecuted " that does not expect from PD printer 1000.The reason of not receiving predetermined status information at step S11 for example is: PD printer 1000 can be accepted a plurality of print out task, even begin request " StartJob " afterwards having accepted to print, the newJobOK of " DeviceStatus " (equipment state) still remains unchanged, be true (True), so PD printer 1000 does not send " NotifyDeviceStatus " to DSC 3012.Equally, in this case, DSC 3012 operates for false hypothesis based on " newJobOK " safely, state up to PD printer 1000 obtains the affirmation (this is because such possibility is arranged: owing to any reason, the sending of " NotifyDeviceStatus " of expression " newJobOK "=" False " (vacation) is delayed) of " GetDeviceStatus ".

Such hypothesis has been carried out in top description: even almost send simultaneously from the order of DSC 3012 with from the order of PD printer 1000, two orders all are effective.But, also can have a kind of direct printing standard: " in the order of almost sending simultaneously, priority processing is from the order of DSC 3012, ignores and order that discarded PD printer 1000 sends ".In this case, is the scope of examination of step S11 exactly: received the order of sending from PD printer 1000? if among the step S11 be "Yes", then process advances to step S13 through a step (not shown) of ignoring from the order of PD printer 1000.If do not receive order from printer 1000, then process directly advances to step S13.

In the superincumbent direct printing standard, the order that goes out of use of PD printer 1000 can be retransmitted by PD printer 1000.Illustrate such a case below: almost be received simultaneously with " StartJob " from the print command of PC 3010, thereby start print processing from the print data of PC 3010 from DSC 3012." NotifyDeviceStatus " that has been sent by the PD printer 1000 DSC3012 that is identified as " newjobOK "=" True " (very) sends " StartJob " instruction in advance in advance.Almost at the same time, the PD printer 1000 that begins the print data from PC 3010 is printed processing is changed into " newJobOK "=" False " (vacation).In order to give DSC 3012 with this advisory, PD printer 1000 sends one " NotifyDeviceStatus " instruction to DSC 3012.But " NotifyDeviceStatus " instruction that PD printer 1000 sends goes out of use, and " StartJob " instruction that DSC 3012 sends is by priority processing.Because PD printer 1000 has been changed into newJobOK " vacation ", it beams back " NotExecuted " in response to " StartJob " instruction.At this moment, PD printer 1000 must be retransmitted " NotifyDeviceStatus " instruction, to notify " newJobOK "=" False " (vacation) to DSC 3012.At this moment, if DSC 3012 sends next instruction, then can almost send simultaneously again from the instruction (order) of two equipment.

Basically, if two standard state differences that equipment is used for giving an order two equipment will occur and almost give an order the situation that one of them order goes out of use simultaneously.In this case, directly print processing just becomes very unstable, and is in dangerous state.Therefore, the situation of preferably avoiding two equipment almost to give an order simultaneously as far as possible.For this reason, for example, when DSC 3012 detects " PD printer 1000 has sent order " at step S11, can forbid sending " GetDeviceStatus " instruction in the given time, wait for order from PD printer 1000 at step S20 or S17.

Equally, in PD printer 1000, also can be set to forbid within the predetermined time giving an order, wait for order from DSC 3012 from PD printer 1000 as another partner of directly printing.But, if these predetermined forbid that the time is equally long, then the described schedule time in the past after, can almost give an order simultaneously from two equipment again.Consider this possibility, the described schedule time can not fixed, but can dynamically change discontinuously or brokenly.Perhaps, can use forbidding the time of when step S11 " not detecting PD printer 1000 gives an order ", using, up to step S11 " detecting PD printer 1000 gives an order ", and when step S11 " detecting PD printer 1000 gives an order ", upgrade this and forbid the time.As the change ground method regularly of giving an order, it can be senior sending regularly.In order to prevent two equipment variations, can change described timing with predetermined rule to same timing.For example, regularly change method can be set based on the master slave relation of USB.Perhaps, DSC 3012 and PD printer 1000 can comprise with generating the device of timing signal immediately, can come to determine respectively to order according to described timing signal and send regularly.As mentioned above, PD printer 1000 can be set to such state: forbid in the given time giving an order from PD printer 1000, thereby reduce the possibility of almost giving an order simultaneously from two equipment.Also can use various improvement project recited above.

(the 4th embodiment)

The processing that continues printing in the print system of the 4th embodiment from DSC 3012 is described below, and the processing of interrupting print processing.Equally, in this example, the structure of the structure of print system and DSC 3012 and PD printer 1000 with top described be identical, therefore omitted its explanation.

The process flow diagram of Figure 11 is used for illustrating when the print processing according to the DSC 3012 of the 4th embodiment and is interrupted, then the continuation print processing that is performed when specifying expression to print the print button of beginning.

At step S110, judged whether to specify the print button in the action button 3103 of DSC 3012.If be "No" among the step S110, then process advances to step S111, carries out another and handles, and such as the processing corresponding to specified button, perhaps waits stand-by button inputted instruction.If specified print button, then process advances to step S112.Send " GetDeviceStatus " to PD printer 1000,, and, obtain the status information of sending from PD printer 1000 in response to this request with the status information of request PD printer 1000.Process advances to step S113, judges based on the status information of being obtained whether the state of PD printer 1000 is " time-outs ".If be "Yes" among the step S113, then process advances to step S114, and judgement is mistake to have taken place and be provided with " warning " (" Warning ") (for example cable is disconnected), does not still make a mistake.If step S114 is a "Yes", then judge restart be fine (because having received state) of print processing from PD printer 1000.Process advances to step S115, and instruction PD printer 1000 restarts print processing (transmitting " ContinueJob " (continuation task)).

If " time-out " state is not set at step S113, at step S114 another mistake has taken place perhaps, judge that then it is impossible restarting print processing, on the UI of display unit 2700, show the message of such meaning.In this case, for example, display message on display unit 2700 informs that the user can not restart print processing, and/or the selection of print button is disabled.Before determining to press print button, obtain the state of PD printer 1000, and inform whether the switch of user's print button is effective, can avoid the user invalidly to push print button at step S110.

The process flow diagram of Figure 12 is used for the DSC 3012 that illustrates at the 4th embodiment, the printing abort process of carrying out when specifying expression to end the printing pause button of print processing.

At step S121, judged whether to specify the pause button in the action button 3103 of DSC 3012.If be "No" among the step S121, then process advances to step S122, carries out another and handles, and such as the processing corresponding to specified button, perhaps waits stand-by button inputted instruction.If select (to have pushed) pause button, then process advances to step S123, send " GetDeviceStatus " to PD printer 1000, the current state information with request PD printer 1000 obtains status information in response to this request from PD printer 1000.Process advances to step S124, judges based on the status information of being obtained whether the state of PD printer 1000 is " time-out ".If be "Yes" among the step S124, then process advances to step S126.If "No" then advances to S125, judge to print and whether advance.If step S125 is a "Yes", judge that then print processing can end, process advances to step S126, and instruction PD printer 1000 is ended print processing (sending " AbortJob " (aborting task)).

If be "No" among the step S125, judge that then print processing can not end, and on the UI of display unit 2700, show the message of this meaning of expression.In this case, for example, display message on display unit 2700 notifies the user can not end to print, and/or forbid selection to pause button.Before determining to press pause button, obtain the state of PD printer 1000, and inform that whether the user is effective to pushing of pause button, can avoid the user invalidly to push pause button at step S121.

(the 5th embodiment)

The process flow diagram of Figure 13 is used for illustrating the processing of the print system of fifth embodiment of the invention.The program of carrying out this processing is stored among the ROM3101.Equally, in the 5th embodiment, the structure of DSC 3012 and PD printer 1000 is the same with the embodiment of front, and has omitted its explanation.

In the 5th embodiment, when DSC 3012 when PD printer 1000 sends any order, the response of 1000 pairs of these orders of PD printer is notified to DSC 3012.If this response comprises the content of not estimating, then DSC 3012 sends " GetDeviceStatus " to PD printer 1000, obtains the current state of PD printer 1000.When the state that obtains be according to just at the described state that obtains the order estimation of sending before action and the response contents, then carry out normal process.On the other hand, if described state is the state of not estimating, then carry out processing corresponding to this state.

At step S50, begin request as printing, " StartJob " instruction is sent to PD printer 1000.Process advances to step S51, if receive printing the beginning request responding from PD printer 1000, then determines its content.If content comprises expression and can not carry out " NotExecuted " of this " StartJob " instruction that then process advances to step S52, sends " GetDeviceStatus " instruction to PD printer 1000.At step S53, DSC 3012 waits are obtained the current state of PD printer 1000 from the response to this instruction of PD printer 1000.At step S54, analyze the reason that described printing sign on is not performed.If reason is excluded, then process advances to step S55, changes UI and shows, waits for that the user uses the instruction of action button 3103 inputs.Begin request if imported printing at step S56, then process advances to step S50, carries out above-mentioned processing.Note, if the order of having selected to be different from print request at step S50 then carry out corresponding the processing, but Figure 13 does not illustrate this processing.

At step S51, if response contents is not " NotExecuted ", then process advances to step S57, judges whether content is " NotSupported ".If content is " NotSupported ", then process advances to step S58.Support owing to can not get PD printer 1000 in " StartJob " instruction of preceding sending for example shows " impossible designation " (can't select/specify) on the UI of display unit 2700, expression PD printer 1000 is not supported this order.Do not support the implication of " StartJob " instruction to comprise that PD printer 1000 do not support the situation of " StartJob " instruction itself, also comprise such situation: PD printer 1000 is supported " StartJob " instruction itself, but, therefore cause not supporting current " StartJob " instruction of sending owing to specified paper size or the paper type (project that is not supported) that is not supported.In this case, be similar to aforesaid example, can rebuild UI, forbidding is to the selection of inappropriate antiquarian or paper type, to get rid of the print conditions that is not supported.This can reduce such possibility: when sending " StartJob " instruction once more, receive " NotSupported " once more from PD printer 1000.At this moment, can carry out and for example confirm the paper size that PD printer 1000 is supported or the processing of paper type.After UI changed like this, process advanced to step S55, waited for the next instruction input, and forwarded corresponding processing to.

At step S57, if response contents is not " NotSupported ", then process advances to step S59.This supposition response is normal (" OK ") basically.At step S59, judge in the given time whether sent predetermined state notifying " NotifyDeviceStatus " from PD printer 1000.Suppose print out task of 1000 acceptance of PD printer.If sent " StartJob " instruction that begins to ask as printing, the newJobOK that the expression PD printer 1000 of " NotifyDeviceStatus " can not be accepted next print out task must be " vacation ".For this reason, if received the predetermined condition responsive that begins to ask corresponding to printing at step S59, then process advances to step S63, continues normal running, complete operation then.

At step S59, if do not receive predetermined status information in the given time, then process advances to step S60, sends " GetDeviceStatus " to PD printer 1000, obtains the state of PD printer 1000.If receive response from PD printer 1000 at step S61, then process advances to step S62, judges whether the state that is obtained is just obtaining the pairing estimated state of order that sends before action and the response.If step S62 is a "Yes", then process advances to step S63, carries out normal process.If what obtain is not the state of estimating, then process advances to step S64, carries out the processing corresponding to this state.

Among the 5th embodiment, an example of " corresponding to the estimated state of response " is a kind of like this state: begin request to receive " OK " although sent printing at step S50, when not sending " NotifyDeviceStatus " in the given time, as " printing " (printing) of the result who sends " GetDeviceStatus ".In this case, be owing to the hypothesis of any reason (for example, having spent long period transmitted image file) based on the delay of sending of " NotifyDeviceStatus ", can continue normal process.As a kind of different state among the 5th embodiment,, can beam back the state of not representing " printing " in response to sending of " GetDeviceStatus ".In this case, it is contemplated that various situations: because any former thereby cause printing and begin request and be not normally processed, perhaps in the very short time printing begins to ask to send after, owing to the environment of PD printer 1000 causes printing to be cancelled.These reasons should combine to come definite processing subsequently with another status information (for example error message).Use the structure of the 3rd embodiment can realize more stable direct print processing equally, simultaneously.

In the 5th embodiment, change the timing of the request of sending based on view data provider's processing.Particularly, image provides equipment (camera) to send predetermined order to recording unit (printer).After image provides equipment to send described predetermined order, the command response whether signal that its judgement receives from recording unit is scheduled to.If image provides equipment to judge that this signal is not the command response of being scheduled to, then this image provides equipment to change when sending Next Command and sends timing.

But the present invention also can be applied to receive the equipment or the recording unit of view data.Particularly, the equipment of reception view data or recording unit send predetermined order provides equipment to image.After this equipment or recording unit sent described predetermined order, whether predetermined it is judged from image provided signal that equipment receives command response.If it is not the command response of being scheduled to that this equipment or recording unit are judged this signal, this equipment or the recording unit that then receive view data change the timing of sending Next Command.

(the 6th embodiment)

The foregoing description has mainly been described the processing among the DSC 3012.The 6th embodiment will describe PD printer 1000 obtains view data from DSC 3012 processing.Hardware configuration among the 6th embodiment is identical with first embodiment, has omitted its explanation.

The process flow diagram of Figure 14 is used for illustrating that the image data acquisition of the PD printer 1000 of sixth embodiment of the invention handles.The program of carrying out this processing is stored among the program storage 3003a, and carries out under the control of DSP3002.

When sending print request (" StartJob ") from DSC 3012, begin this processing with appointment beginning print processing.At step S31, " GetFileInfo " (obtaining fileinfo) is sent to DSC 3012, to ask the information of relevant DSC 3012 desired image files.At step S32, when sending the information (file size, attribute etc.) of relevant image file from DSC 3012, obtain and be included in the described information project of representation file capacity.Process advances to step S33 to judge whether receiving and to handle whole file simultaneously.This memory capacity that is based on the free area in the storer 3003 of PD printer 1000 is for example judged.If judge to receive all images data simultaneously, then process advances to step S34, reads this image file.Specify the start address and the amount of reading, to ask the parts of images data of this image file.This use " GetPartialFile " (obtaining partial document) is carried out.According to described start address and the amount of reading, DSC 3012 reads the parts of images data of appointment from image file, and sends the parts of images data to PD printer 1000.Described parts of images data are handled and printed to the PD printer 1000 that has received described parts of images data at step S35 at step S36.Process advances to step S37, judges whether to have printed all images data of described image file.If step S37 is that then process does not advance to step S34 ', request next part view data.Carry out this processing repeatedly, all be received and print up to entire image file in step S32 appointment.

Can disposable reception and handle the view data of image file if judge at step S33, then process advances to step S38, all data of the image file of request DSC 3012.At step S39, all images data of the image file that sends from DSC 3012 based on this request are received and print.

The process flow diagram of Figure 15 is used for illustrating another example that the image data acquisition of the PD printer 1000 of sixth embodiment of the invention is handled.The program of carrying out this processing is stored among the program storage 3003a, and carries out under the control of DSP3002.

When sending print request (" StartJob ") from DSC 3012, begin this processing with appointment beginning print processing.At step S41, " GetFilelnfo " (obtaining fileinfo) is sent to DSC 3012, to ask the information of the specified image file of relevant DSC 3012.At step S42, if send the information of relevant image file from DSC 3012, then process advances to step S43 to judge whether image file comprises thumbnail (key map).Whether if image file comprises thumbnail, then process advances to step S44, judge and use control module 1010 to specify index prints.If specified index prints, then process advances to step S45, the thumbnail data (sending " GetThumb " (obtaining thumbnail)) of request DSC 3012, and obtain data.Process advances to step S46, prints based on the thumbnail data execution index that is obtained.

At step S43, if image file does not comprise thumbnail, if perhaps do not have assigned indexes to print at step S44, then process advances to step S33 (Figure 14), carries out aforesaid image print and handles.

Like this, according to the 6th embodiment,, can and import from DSC 3012 changes from the DSC 3012 disposable image data amounts that obtain according to the memory span and the handling property of PD printer 1000.

Can detect in advance and in the image file of DSC 3012, whether store thumbnail.When assigned indexes in PD printer 1000 is printed, in PD printer 1000, can omit thumbnail and generate processing.Like this, can printing speed thumbnail (key map).

The present invention can be applied to comprise the system of a plurality of equipment (for example principal computer, interfacing equipment, reader and printer), perhaps the equipment that is made of single assembly (for example duplicating machine or facsimile recorder).

Purpose of the present invention can also be by storage being used to realize the foregoing description the storage medium (perhaps recording medium) of software program code of function (processing of carrying out in camera one side and the various print processing of carrying out in printer one side) offer a kind of system or equipment is realized.The program code that is stored in the described storage medium is read and carried out to the computing machine of this system or equipment (perhaps CPU or MPU).In this case, the program code that is read out from storage medium is realized the function of the foregoing description, and the storage medium of storing said program code constitutes the present invention.When computing machine is carried out the program code of being read, realize the function of the foregoing description.In addition, the present invention also comprises such situation: when the operating system etc. of operation on computers during based on the instruction operating part of described program code or whole actual treatment, realize the function of the foregoing description.

In addition, the present invention includes such situation: in the storer of the function expansion card that inserts computing machine, perhaps in the storer of the functional expansion unit that is connected to computing machine, write after the program code that storage medium is read, the CPU of described function expansion card or functional expansion unit is based on instruction operating part or whole actual treatment of described program code, thus the function of realization the foregoing description.

As mentioned above, according to described each embodiment, after the print processing of interrupting by the cable that disconnect to connect DSC and PD printer in the printer, by stube cable once more, print processing can be restarted, thereby print processing can be restarted reliably to print.

According to sending the print processing of the view data of printer to, when restarting to print, change the view data of retransmitting to printer from DSC based on the print processing of DPOF file or from the DSC order.No matter under any situation, can restart reliably to print.

When DSC in the foregoing description when printer is given an order such as " StartJob " or AbortJob, even printer without any response, DSC has also estimated to have set predetermined state, and can determine next operation.DCS also sends the order of affirmation state to printer, and the current state of identification printer.

When the PD printer in response when DSC beams back concrete state, DSC forwards corresponding processing to.For example, for " NotExecuted " or " NotSupported ", DSC sends the order at the state of last command queries printer, and based on responding the Next Command that decision will be sent.For back one order, the order that printer sends before not being supported in, so DSC for example carries out the processing of the UI that change shows on display unit, not send identical order subsequently.This can prevent to retransmit useless order to printer.

In addition, when PD printer and DSC almost gave an order simultaneously, two or at least one equipment were forbidden giving an order in the given time.This can reduce once more from described two possibilities that equipment is almost given an order simultaneously.

According to described embodiment,, can adjust from the image data amount that DSC once obtains according to the memory capacity and the handling property of printer.Can be written into, processing and print image data.

The invention is not restricted to the foregoing description, in essential scope of the present invention, can make variations and modifications.Therefore, in order to allow the public know protection scope of the present invention, write appending claims.
