  In general, in an environment where a plurality of printing apparatuses are used, a printing apparatus that is normally used is often assigned to each user in consideration of travel time such as the distance from the user's seat to the printing apparatus being short. Further, whether or not the user desires alternative printing when printing instructed to a printing apparatus to be normally used is waiting to start (waiting) depends on a waiting time (waiting time) until printing is started on the printing apparatus. ), Depending on conditions such as travel time and labor for returning to the printing apparatus where the alternative printing has been performed.

  For example, when alternative printing is performed by a distant printing device, the travel time required to obtain the printed matter becomes long and annoying, so that the printing start waiting time instructed to the printing device to be used normally is not necessary. If short, alternative printing is not desired, and if the start waiting time is long, alternative printing is desired. In addition, even when the alternative printing is performed by a relatively nearby printing apparatus, it is desired that the printing instructed to the normally used printing apparatus should be performed by the printing apparatus if possible, and may be waited for some time. Such a case can be considered.

  On the other hand, the techniques of Patent Documents 1 and 2 do not consider transfer of print data according to the print start waiting time as described above, and the printing apparatus cannot execute or continue the instructed printing. Since the print data is immediately transferred to another printing apparatus to request alternative printing, it is impossible to meet the user's wishes as described above.

  Further, in Patent Document 3, the print server is configured to reply to the terminal device only whether or not a print instruction is accepted (print data can be spooled / impossible). Not considered. For this reason, the user cannot make a determination as to whether or not to request alternative printing from another printer with reference to the print start waiting time, and this technique cannot meet the above user needs.

  The present invention is intended to solve the above-described problem. When printing for print data received from a terminal device is waiting to be started, print data is transferred to an alternative printing device according to the waiting time. An object is to provide an apparatus and a printing system.

  The gist of the present invention for achieving the object lies in the inventions of the following items.

[1] a communication unit;
A printing section;
When printing by the printing unit with respect to the print data received from the terminal device through the communication unit is awaiting start and it is determined that the time until the printing can be started is a predetermined time or more, the print data is transmitted to the communication unit. A control unit that transfers to the alternative printing device through
A printing apparatus comprising:

  In the above invention, when printing for the print data received from the terminal device is waiting to be started, the printing device determines whether or not the time until the printing can be started is a predetermined time or more. The predetermined time is a time (transfer waiting time) serving as a threshold for starting transfer of print data. The predetermined time can be set to an arbitrary time (fixed time). For example, the predetermined time can be set in advance in the printing apparatus, or can be set in the terminal apparatus when instructing printing from the terminal apparatus to the printing apparatus. Is possible. When a predetermined time is set by the terminal device, print data to which the predetermined time is added is transmitted from the terminal device to the printing device.

  When the printing apparatus determines that the time until the printing that has been waiting to be started can be started is a predetermined time or more, the printing apparatus transfers the print data relating to the printing to the alternative printing apparatus and requests the alternative printing. . As described above, when printing is waiting to be started, transfer of print data from the printing apparatus to the alternative printing apparatus is performed according to a predetermined time.

[2] The control unit measures the time from the time when the printing is awaited to start, and transfers the print data when it is determined that the measurement time is not less than the predetermined time without starting the printing. The printing apparatus according to [1], wherein the printing apparatus is executed.

  In the above invention, when printing instructed from the terminal device is waiting to be started, the transfer of the print data from the printing device to the alternative printing device is measured time (actual progress from the time when the printing is waiting to start). Time). In other words, when it is determined that the print waiting for start continues in the start wait state and is not started and the measurement time is equal to or longer than the predetermined time, print data transfer is executed.

  In this way, if the time is only measured and the predetermined time is compared, a complicated configuration or processing is not necessary, so the timing for starting printing (time until printing can be started) is grasped. The configuration and processing can be simplified.

[3] The control unit predicts a time until the printing can be started, and executes the transfer of the print data when it is determined that the predicted time is equal to or longer than the predetermined time. The printing apparatus according to [1].

  In the above invention, when printing instructed from the terminal device is waiting to be started, the transfer of the print data from the printing device to the alternative printing device is executed based on the estimated time until the printing can be started. . That is, when it is determined that the predicted time is equal to or longer than the predetermined time, the print data is transferred.

  In this way, the configuration for predicting the timing at which printing is started (the time until printing can be started) prints compared to the configuration in [2] in which the timing is grasped from the actual elapsed time (measured time). It becomes possible to quickly determine whether or not to transfer data, and when transferring print data, it is possible to promptly make a substitute print request to the substitute printing apparatus.

[4] The printing apparatus according to any one of [1] to [3], further including a transfer destination setting unit that receives a setting of a transfer destination to which the print data is transferred.

  In the above invention, a plurality of transfer destinations and a priority order for transferring print data to the plurality of transfer destinations can be set through the transfer destination setting unit described in the invention [4].

  For example, if there is only one transfer destination, the start of alternative printing will be delayed even if the print data is transferred if the alternative printing apparatus that is the transfer destination is in an operational state and cannot be printed immediately. On the other hand, when there are a plurality of transfer destinations, the options of the transfer destinations are widened, and it becomes easy to transfer the print data to an alternative printing apparatus capable of immediate printing, and it is easy to avoid the start delay of the alternative printing.

  Further, the priority order can be arbitrarily determined based on conditions such as the distance from the user's seat to the alternative printing device as the transfer destination, the performance of the alternative printing device, and the like. By determining such priorities, alternative printing can be performed by an alternative printing apparatus that is more convenient for the user, and convenience is improved.

[6] The printing apparatus according to any one of [1] to [5], further including a time setting unit that receives the setting of the predetermined time.

  In the above invention, it is possible to set a predetermined time as a time (transfer waiting time) until the transfer of print data is started through the time setting unit included in the printing apparatus.

[7] Before executing the transfer of the print data, the control unit communicates with the alternative printing device through the communication unit to check whether the printing device can perform immediate printing, and cannot perform immediate printing. In some cases, the transfer based on the determination is stopped. The printing apparatus according to any one of [1] to [6], wherein:

  In the above invention, before transferring print data, the printing apparatus communicates with an alternative printing apparatus as a transfer destination to check whether the printing apparatus can perform immediate printing, and when immediate printing is not possible, substitute printing is performed. Cancels the transfer of print data to the device. Thereby, it can be avoided that the print data is transferred to an alternative printing apparatus that cannot perform immediate printing and the start of the alternative printing is delayed.

[8] A display unit is further provided,
The printing apparatus according to any one of [1] to [7], wherein when the print data is transferred, the control unit displays a history related to the transfer on the display unit.

  In the above invention, the user who has instructed printing to the printing apparatus through the terminal device transfers the print data displayed on the display unit of the printing apparatus instructed to print when the printing is performed by the alternative printing apparatus instead. From the history, the information on the transfer destination can be confirmed. As a result, it is possible to easily grasp which printing apparatus (alternative printing apparatus) has executed the alternative printing.

[9] When the transfer of the print data is executed, the control unit notifies the terminal device that is the transmission source of the print data through the communication unit, [1] to [1] 8]. The printing apparatus according to any one of [8].

  In the above invention, a user who has instructed printing to a printing device through a terminal device relates to transfer of print data notified from the printing device to his / her terminal device when the printing is performed by an alternative printing device instead. From the information, it is possible to confirm the information of the transfer destination. As a result, it is possible to easily grasp which printing apparatus (alternative printing apparatus) has executed the alternative printing.

  In the invention [8], the user cannot grasp the transfer destination information or the like unless he / she goes to the printing apparatus and confirms the history related to the transfer of the print data. In the invention of [9], the user can grasp the transfer destination information and the like with his / her terminal device without going to the printing device, and convenience is improved.

[10] A printing system having a terminal device and a printing device,
The terminal device accepts a setting of a waiting time until the printing device starts to transfer print data to the alternative printing device, and transmits the print data to which the time information indicating the time is added to the printing device;
The printing apparatus waits for printing on the printing data received from the terminal apparatus to start, and the time until the printing can be started is indicated by the time information added to the printing data. A printing system that transfers the print data to an alternative printing device when it is determined that the time is over.

  In the above invention, when the terminal device instructs the printing device to perform printing by the user's operation, if the waiting time until the printing device starts transferring the print data to the alternative printing device is set, the time is set. The print data to which the time information shown is added is transmitted to the printing apparatus. The waiting time is a time serving as a threshold for starting the transfer of print data, similar to the predetermined time described in the invention of [1], and the user can set an arbitrary time (fixed time).

  The printing apparatus waits for printing on the printing data received from the terminal apparatus to be started, and the time until the printing can be started is equal to or longer than the time indicated by the time information added to the printing data. When the determination is made, the print data is transferred to the alternative printing apparatus to request alternative printing.

  In the transfer of print data based on the above determination, as in the invention of [2], the time is measured from the time when printing is awaited to start, and the measured time is not less than the predetermined time without starting the printing. When the determination is made, transfer of the print data is executed, or, similarly to the invention of [3], when the time until printing can be started is estimated and the estimated time is determined to be equal to or longer than the predetermined time. Transfer of print data may be executed.

  In addition, as in the invention of [7], the printing apparatus in this printing system confirms whether the alternative printing apparatus can immediately print by communicating with the alternative printing apparatus before transferring the print data. When immediate printing is impossible, the transfer of print data based on the above determination may be stopped. Furthermore, as in the invention of [8], when the print data is transferred, a history related to the transfer is displayed, or when the print data is transferred as in the invention of [9], the transfer is displayed. Such information may be notified to the terminal device that is the transmission source of the print data.

  As a result, when printing instructed from the terminal device to the printing device is waiting to be started, the transfer of print data from the printing device to the alternative printing device is performed according to the waiting time set by the terminal device. . Further, the user can set the waiting time on the terminal device.

  According to the printing apparatus and the printing system of the present invention, when printing for print data received from a terminal apparatus is waiting to be started, the print data can be transferred to the alternative printing apparatus according to the waiting time.

  As a result, when printing instructed by the user from the terminal device is waiting to be started at the printing apparatus, the alternative printing apparatus does not immediately start the alternative printing, but starts printing by a predetermined time (waiting time). If possible, printing is started by a printing apparatus desired by the user (instructed to print), and a printed matter can be acquired from the printing apparatus. Further, if the printing cannot be started by a predetermined time (waiting time), the alternative printing apparatus starts the alternative printing, and the printed material can be acquired from the printing apparatus. Therefore, the convenience related to the acquisition of the printed material when printing is waiting to start is improved.

Further, a transfer waiting time designation button 65 and a transfer waiting time display column 66 that perform the same functions as those described in FIG. 4 are displayed.

  The same operation as that described with reference to FIG. 4 is performed through the transfer setting screen 60, and the IP addresses of the two MFPs 20 as the desired transfer destinations and the desired transfer waiting time are input.

  For example, when setting the transfer destination priority No. 1 to the multi-function device B in the multi-function device A in FIG. 1, the IP address of the multi-function device B is “192.168.10.10” after the transfer destination designation button 61 is pressed. .11 "or the like is entered, the IP address is displayed in the corresponding transfer destination display field 62 as shown in FIG. Similarly, when the transfer destination with the second priority order is set to the multi-function device C in the multi-function device A of FIG. 1, the IP address of the multi-function device C is “192.168 .. When "10.12" is entered, the IP address is displayed in the corresponding transfer destination display field 64 as shown in FIG. In the transfer waiting time display field 66, the input transfer waiting time is displayed as “3 minutes”, for example.

  As described with reference to FIG. 4, the setting is completed when a predetermined confirmation operation is performed after the transfer destination and the transfer waiting time are input, and the transfer setting information is stored in the nonvolatile memory 25. In this case, each transfer destination is stored with a priority associated with it.

  It is possible to set three or more transfer destinations. In any case, when a plurality of transfer destinations are set, when the user designates the desired number (N) of transfer destinations through the operation display unit 27 and performs a predetermined operation, the transfer setting screen displays the priority order of the transfer destinations. Only the number of sets (N sets) specified by the transfer destination designation buttons with (1st to Nth) and the corresponding transfer destination display fields are displayed. Through the operation described with reference to FIG. 5 through this transfer setting screen, a plurality of transfer destinations and priorities can be set. The priority order can be arbitrarily determined based on conditions such as the distance from the user's seat to the multifunction device 20 as the transfer destination and the performance of the multifunction device 20 as the transfer destination.

  FIG. 6 shows an example of a job status screen 70 displayed on the operation display unit 27 of the multifunction machine 20. The job status screen 70 displays the name (user name) of the user who requested the job (print job), the file name of the requested job, and the status (status) in units of jobs. A name 71 (title column) is displayed.

  In this example, while the MFP A in FIG. 1 is executing the print job “Job1.doc” received from the terminal 10 of the user B, the print job “Job2.doc” from the user A terminal 10. The job status screen 70 in the case of receiving In this case, as shown in the drawing, the status of the print job 72 (Job1.doc) requested by the user B is displayed as “printing”, and the print job 73 (Job2.doc) requested by the user A is in the status. Appears as "Waiting".

  Next, the operation of the multifunction machine 20 will be described.

  7 to 9 show the flow of processing relating to transfer of print data when the multi-function device 20 is requested by the terminal 10 for a print job.

  In the present embodiment, as described with reference to FIGS. 4 and 5, one or more transfer destinations and transfer waiting times are set in advance in the multifunction machine 20, and the transfer setting information is stored in the nonvolatile memory 25. Has been. Then, as described above, printing for the print data received from the terminal 10 is waiting to start (waiting), the time is measured from the time when this printing is waiting to start, and the measured time is waiting to be transferred without starting printing. When it is determined that the time has expired, the print data is transferred to another multifunction device 20 that is a transfer destination. In addition, before executing print data transfer, communication with the transfer destination multifunction device 20 is performed to check whether the multifunction device 20 can immediately print. Here, it is determined that immediate printing is possible when the MFP 20 as the transfer destination is in a standby state, and it is determined that immediate printing is impossible when it is in operation.

  For example, when the user A's terminal 10 shown in FIG. 1 requests the MFP A to print, the user A's terminal 10 temporarily stores the generated print data in a printing memory and combines the print data. When transmitted to the machine A (arrow A in the figure), the memory for printing is released. The multifunction device A waits for printing to start for the print data received from the terminal 10 of the user A, measures the time from the time when the printing is waited to start, and does not start printing, but the measured time exceeds the transfer waiting time. Then, for example, if the multifunction device B is in a standby state after communicating with the transfer destination multifunction device B, the print data is transferred to the multifunction device B (arrow T in the figure).

  Specifically, when the MFP 20 starts the processing shown in FIG. 7 (Start) and receives print data from the terminal 10 via the network 2 (step S101), the CPU 11 checks whether a preceding print job exists. (Step S102).

  If there is no preceding print job (step S102; No), the CPU 11 causes the printer unit 30 to start printing the received print data (step S103), and ends this processing (End).

  If there is a preceding print job (step S102; Yes), the CPU 11 waits for the received print data to start (waiting), and the job status screen displayed on the operation display unit 27 (see FIG. 6) Then, the status of the print job related to the print data waiting to be started is displayed as “waiting”. Further, the CPU 11 measures the time from the time when the print data is waiting to be started (step S104), monitors whether the measured time is longer than the transfer waiting time stored in the nonvolatile memory 25, It is monitored whether or not the print job is completed (step S105; No → Step S106; No → Return to Step S105).

  If it is determined that the preceding print job has ended (step S106; Yes) before the measurement time exceeds the transfer waiting time (step S105; No), the CPU 11 responds to the print data in the start waiting state. Printing is started by the printer unit 30 (step S103), and this processing is ended (End).

  If it is determined that the measurement time has exceeded the transfer waiting time (step S105; Yes) before the preceding print job ends (step S106; No), the CPU 11 transfers the transfer destination stored in the nonvolatile memory 25. Is confirmed (step S107).

  When the number of transfer destinations is one (step S107; one), the process proceeds to step S111 in FIG. 8, and the CPU 11 performs network 2 based on the IP address of the transfer destination stored in the nonvolatile memory 25. Communicating with the relevant multifunction device 20 connected to, and confirming the status of the transfer destination multifunction device 20 (step S111).

  As a result of confirmation, if the transfer destination multifunction device 20 is on standby (step S112; in standby), the CPU 11 transfers the print data in the start waiting state to the transfer destination multifunction device 20 through the network 2. (Step S113). After transferring the print data, the CPU 11 notifies the information (name and the like) of the transfer destination multifunction machine 20 to the terminal 10 that is the print data transmission source via the network 2 (step S114). Further, when an operation for displaying a history relating to the transfer of print data is received through the operation display unit 27, the CPU 11 operates a history relating to the transfer of the print data (information on the transfer destination multifunction device 20, transfer date, etc.). It is displayed on the display unit 27. Then, this process ends (End).

  If the MFP 20 is operating as a result of checking the state of the MFP 20 as the transfer destination (step S112; operating), the CPU 11 determines whether the preceding print job has ended (step S112). Step S115). If it is determined that the preceding print job has not ended (step S115; No), the process returns to step S111, and the processing steps after step S111 described above are similarly performed (steps S111 to S111). If it is determined that the preceding print job has been completed (step S115; Yes), the CPU 11 causes the printer unit 30 to start printing for the print data that is in a start wait state (step S103 in FIG. 7). Is terminated (End).

  On the other hand, when the number of transfer destinations is plural (step S107; plural), the process proceeds to step S121 in FIG. 9, and the CPU 11 sets N indicating the priority (number) of the transfer destination to 1 (step S121). N = 1). Subsequently, the CPU 11 communicates with the corresponding multifunction device 20 connected to the network 2 based on the IP address of the transfer destination N stored in the nonvolatile memory 25, and the state of the multifunction device 20 of the transfer destination N is changed. Confirm (step S122).

  As a result of confirmation, if the MFP 20 of the transfer destination N is in standby (step S123; in standby), step S124 and step S125 having the same processing contents as step S113 and step S114 described in FIG. This is performed for the multifunction machine 20. When the MFP 20 at the transfer destination N is operating (step S123; operating), the CPU 11 checks whether the transfer destination of the next priority is stored in the nonvolatile memory 25 (step S126).

  If the transfer destination of the next priority is stored (step S126; Yes), the CPU 11 adds 1 to N indicating the priority of the transfer destination (step S127; N = N + 1), and returns to step S122. The above-described processing steps after step S122 are similarly performed (steps S122 and after). If the next priority transfer destination is not stored (step S126; No), the CPU 11 determines whether or not the preceding print job has ended (step S128).

  If it is determined that the preceding print job has not ended (step S128; No), the process returns to step S121, and the processing steps after step S121 are similarly performed (steps S121 to S121). If it is determined that the preceding print job has been completed (step S128; Yes), the CPU 11 causes the printer unit 30 to start printing for the print data that is in a start-waiting state (step S103 in FIG. 7). Is terminated (End).

  When print data is transferred from the multifunction device 20 to another multifunction device 20 as a transfer destination, the transfer destination multifunction device 20 executes alternative printing on the received print data.

  As described above, the MFP 20 according to the present exemplary embodiment presets transfer of print data to another MFP 20 as a transfer destination when printing for print data received from the terminal 10 is waiting to start. Executes according to the transfer waiting time. That is, the print data transfer is not started because the print waiting for start continues in the start wait state (the preceding job has not been completed), and the measured time (actual time from when the print is waited for start) This is executed when it is determined that the (elapsed time) is equal to or longer than the above transfer waiting time.

  As a result, when the printing instructed by the user from the terminal 10 is awaiting to be started at the multifunction device 20, the alternative printing is not immediately started at the multifunction device 20 as the transfer destination, but the printing is performed by the transfer waiting time. If started, the printed matter can be acquired from the multifunction machine 20 desired by the user (instructed to print). Also, if the printing is not started before the transfer waiting time and the immediate destination printing is possible (during standby) at the transfer destination multifunction device 20, alternative printing is executed by the multifunction device 20 and a printed matter is acquired from the multifunction device 20. can do. Therefore, the convenience related to the acquisition of the printed material when printing is waiting to start is improved.

  Further, since only the time from the point when printing is waiting to start is measured and the measured time is compared with a preset transfer waiting time, no complicated configuration or processing is required. As a result, it is possible to simplify the configuration and processing for determining whether or not to transfer print data according to the transfer waiting time.

  Also, before transferring the print data, the multifunction device 20 communicates with the transfer destination multifunction device 20 to check whether the multifunction device 20 can perform immediate printing. If immediate printing is not possible, the preceding job Is compared with the timing at which the transfer destination multifunction device 20 becomes ready to print, and it is determined whether or not to transfer the print data. That is, when the end timing of the preceding job is earlier, the transfer of the print data is stopped. If the timing at which the transfer destination multifunction device 20 is ready for printing is earlier, transfer of print data is executed. As a result, it is possible to avoid that the print data is transferred to the transfer destination multifunction peripheral 20 where immediate printing is impossible and the start of alternative printing is delayed.

  In addition, when a plurality of print data transfer destinations are set, options for the transfer destinations are widened as compared with the case where one transfer destination is used. This makes it easy to transfer the print data to the MFP 20 that can print immediately, and avoids long-term continuation of the print start waiting state and delay of the start of alternative printing that are likely to occur when the processing time of the preceding job becomes long. It becomes easy.

  Further, as described above, the priority order can be arbitrarily determined based on the distance from the user's seat to the multifunction device 20 as the transfer destination, the performance of the multifunction device 20, and the like. By determining such priorities, alternative printing is performed by the multifunction device 20 (alternative printing device) that is more convenient for the user, and convenience is improved.

  In addition, the multifunction device 20 accepts reception of print data from the terminal 10 even during processing of a preceding job, and when the print data is transferred, the received print data is transferred to the transfer destination. As a result, the terminal 10 can transmit the print data even when the multifunction device 20 is processing the preceding job, and it is not necessary to store the print data for transfer to the transfer destination. Therefore, the terminal 10 can quickly release the memory for generating and temporarily storing the print data, and the processing load when requesting the MFP 20 to perform printing during processing of the preceding job is reduced. It becomes like this.

[Second Embodiment]
In the first embodiment, the case has been described in which the time to compare with the transfer waiting time in the determination relating to the transfer of the print data is the measurement time from the print start waiting time. In the second embodiment, printing is performed. A case will be described in which the estimated time until the start is possible.

  The configuration of the MFP according to the second embodiment is basically the same as the configuration of the MFP 20 described with reference to FIG. 3, and only the program of the CPU 11 stored in the ROM 23 is different. In the multi-function device 20 according to the second embodiment, the CPU 11 executes a program, and when printing by the printer unit 30 for print data received from the terminal 10 through the network communication unit 32 is awaiting start, this printing is performed. A function of predicting the time until the start is possible and determining that the predicted time is equal to or longer than a predetermined time (transfer waiting time) and transferring the print data to another multifunction device 20 through the network communication unit 32. Fulfill.

  FIG. 10 shows a flow of processing relating to transfer of print data when the multi-function device 20 according to the second embodiment receives a print job request from the terminal 10. Note that the processes in FIGS. 8 and 9 similar to those in the first embodiment will be described with reference to these drawings.

  When the MFP 20 starts this processing (Start) and receives print data from the terminal 10 via the network 2 (step S201), the CPU 11 checks whether a preceding print job exists (step S202).

  If there is no preceding print job (step S202; No), the CPU 11 causes the printer unit 30 to start printing the received print data (step S203), and ends this processing (End).

  If there is a preceding print job (step S202; Yes), the CPU 11 predicts the processing time of the preceding print job (step S204).

  Specifically, as described in the first embodiment, the header of the print data received from the terminal 10 includes the name of the document to be printed (file name), the size of the print data, the document data, The number of pages, recording paper size, printing orientation, layout, printing mode (single / double-sided), color mode, resolution, number of copies, and the like are added.

  The CPU 11 calculates the time required for processing the remaining print job at the present time based on the information related to the print job processing, the print processing capability (processing speed) of the multifunction device 20, and the like.

  Subsequently, the CPU 11 compares the predicted time required for processing the preceding print job with the transfer waiting time stored in the nonvolatile memory 25, and determines whether the predicted time is equal to or longer than the transfer waiting time (step S205). ). When it is determined that the predicted time is less than the transfer waiting time (step S205; No), the CPU 11 sets the received print data state to wait for start (waiting) (step S206) and displays it on the operation display unit 27. On the job status screen (see FIG. 6), the status of the print job related to the print data waiting to be started is displayed as “waiting”. Then, it is monitored whether or not the preceding print job has ended (step S207; No → return to step S206). If it is determined that the preceding print job has ended (step S207; Yes), the above start The printer unit 30 is started to print the print data in the waiting state (step S203), and this processing is ended (End).

  When it is determined that the estimated time required for processing the preceding print job is equal to or longer than the transfer waiting time stored in the nonvolatile memory 25 (step S205; Yes), the CPU 11 transfers the transfer destination stored in the nonvolatile memory 25. Is confirmed (step S208).

  If the number of transfer destinations is one (step S208; one), the process proceeds to step S111 in FIG. 8, and steps S111 and S112 described in the first embodiment are similarly performed. If the standby state is set in step S112, steps S113 and S114 are similarly performed, and the present process is terminated (End). If it is in operation in step S112, the process returns to step S205 in FIG. 10 shown in the direction E in the figure, and the processing steps after step S205 described above are similarly performed (step S205).

  On the other hand, when the number of transfer destinations is plural (step S208; plural), the process proceeds to step S121 in FIG. 9, and steps S121 to S123 described in the first embodiment are similarly performed. If it is in the standby state in step S123, step S124 and step S125 are performed in the same manner, and this process ends (End). If the operation is in step S123, step S126 is performed in the same manner. If the determination in step S126 is affirmative, step S127 and subsequent steps are similarly performed. In the case of negative determination in step S126, the process returns to step S205 in FIG. 10 shown in the direction E in the figure, and the processing steps after step S205 described above are similarly performed (step S205).

  In step S205 returned from step S112 in FIG. 8 or step S126 in FIG. 9, the predicted time decreased with the passage of time (the remaining predicted time obtained by subtracting the elapsed time from the predicted time required for processing the preceding job first calculated). Are compared with the specified transfer latency. When it is determined that the reduced predicted time is less than the prescribed transfer waiting time (step S205; No), the process proceeds to step S206, and the MFP 20 that has received the print data from the terminal 10 Printing is executed.

  As described above, regarding the transfer waiting time, it is more advantageous that printing that has been started is printed by the multifunction device 20 rather than immediately by the transfer destination multifunction device 20 (alternative printing device). This is considered to be the time used as a criterion. According to this idea, when the estimated remaining time becomes shorter than the transfer waiting time (remaining estimated time <transfer waiting time), it is more advantageous to print with the multifunction device 20 than the multifunction device 20 of the transfer destination. State is established. Therefore, in the present embodiment, when the operation is being performed in step S112 in FIG. 8 or in the case of a negative determination in step S126 in FIG. 9, the process returns to step S205 in FIG. Compare the predicted time with the transfer latency. Then, when the condition of remaining prediction time <transfer waiting time is satisfied, the transfer of the print data is stopped, and the MFP 20 performs printing.

  For example, if the transfer waiting time is set to 5 minutes and the initial estimated time is 7 minutes, the state is inquired of the transfer destination multifunction device 20, and if it is in operation, the print data transfer is suspended. Is done. Thereafter, when 3 minutes elapses while the transfer destination multifunction peripheral 20 is operating, the remaining estimated time is 4 minutes, which is less than the transfer waiting time. That is, a state in which printing with the multifunction device 20 is more advantageous than the multifunction device 20 as a transfer destination is established. In such a case, the transfer of the print data is stopped and printing is performed by the multifunction device 20.

  As described above, the MFP 20 according to the present embodiment executes transfer of print data when printing instructed from the terminal 10 is waiting to start based on the estimated time until the printing can be started. To do. That is, when it is determined that the predicted time is equal to or longer than the transfer waiting time, the print data is transferred.

  In the configuration of the present embodiment for predicting the timing at which printing is started (time until printing can be started), the configuration of the first embodiment is used to grasp the timing from the actual elapsed time (measurement time). In comparison, it is possible to quickly determine whether or not to transfer print data. As a result, when print data is transferred, a request for alternative printing to the transfer destination multifunction device 20 can be quickly made.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are also included in the present invention.

  For example, in the first and second embodiments described above, the transfer destination and transfer waiting time set in the multi-function device 20 are common to all users. You may comprise so that it can set separately for every user.

  Further, the transfer destination and the transfer waiting time may be set when the terminal 10 instructs the multifunction device 20 to print. For example, the driver program 40 of the MFP 20 installed in the terminal 10 includes a screen for instructing printing from the terminal 10 to the MFP 20 (a print instruction screen displayed on the display unit 16), a transfer destination setting unit, and At least one of the setting unit of the transfer waiting time is displayed and the setting is accepted through the operation unit 17, and the transfer setting information (transfer destination / transfer waiting time) is added to the header of the print data and transmitted to the multifunction device 20. Provide functions.

  For transfer destinations, a plurality of transfer destinations and their priority settings may be accepted. In addition, the setting of the transfer destination and transfer waiting time performed by the terminal 10 can be made common to all print instructions by the terminal 10, or the initial setting and the previous setting can be changed for each print instruction. May be.

  The multi-function device 20 uses the transfer setting information (transfer destination (including the priority when there are a plurality of transfer destinations) / transfer waiting time) added to the header of the print data received from the terminal 10 as shown in FIG. Processes related to print data transfer described with reference to FIG. 9 are executed.

  It is also possible to use both the setting by the terminal 10 and the setting in the multifunction machine 20 together. For example, even when a transfer destination and a transfer waiting time are set in the multifunction device 20 in advance, when transfer setting information is added to the print data, an operation such as giving priority to the transfer setting information may be performed. Good.

  The priority order is also set for a plurality of transfer destinations. The priority order is based on the distance from the MFP 20 to each transfer destination and the processing time of the preceding job at each transfer destination. You may make it judge automatically. For example, the distance to each transfer destination is registered in advance in the multi-function device 20, and the multi-function device 20 inquires and confirms the processing time of the preceding job from each transfer destination before transferring the print data. Then, for each transfer destination, points may be calculated by multiplying the processing time of the preceding job that has been replied and the distance to the transfer destination, and priorities may be assigned in ascending order of the points.

  Further, in confirming whether immediate printing is possible with respect to the print data transfer destination, it is determined that immediate printing is impossible when the transfer destination multifunction device 20 is operating. In addition to this, it may be determined that immediate printing is impossible even when an abnormality occurs.

  8 and 9 in the second embodiment, the flow is different from that of the first embodiment (flow in the direction E in the figure). A similar flow may be used.

  In the first embodiment, whether or not to transfer print data is first determined based on the measurement time (first determination criterion), and if it is determined that transfer is to be performed, The determination is made based on the state of the transfer destination (second determination criterion). Here, if the transfer destination is not ready for immediate printing, the determination is further made based on the processing status of the preceding job and the transfer destination state (third determination criterion).

  In the second embodiment, whether or not to transfer print data is first determined based on the predicted time (first determination criterion). If it is determined that transfer is to be performed, the transfer destination is determined next. The determination is made based on the state (second determination criterion). Here, if the transfer destination is not ready for immediate printing, the determination is made again based on the predicted time (first determination criterion). Hereinafter, the determination based on the transfer destination state (second determination criterion); The determination based on the predicted time (first determination criterion) is repeated.

  As described above, in both cases of the first and second embodiments, whether or not to execute print data transfer is first determined based on a predetermined determination criterion (first determination criterion), and thereafter halfway. Judgment criteria are changed. In other words, a plurality of types of judgment criteria are properly used according to the situation so that a judgment suitable for the situation can be made.

  Further, in the second embodiment, there is a case where the determination based on a predetermined determination criterion (estimated time) is repeatedly performed because the transfer destination multifunction device 20 is in a state where immediate printing is not possible. The determination to be performed again is also included in the determination according to claim 1 that “the time (predicted time) until printing can be started is equal to or longer than a predetermined time (transfer waiting time)”.

  In the MFP 20 according to the embodiment, the touch panel type operation display unit 27 has the functions of the operation unit and the display unit. However, the operation unit and the display unit may be configured separately.

  In addition, the present invention is not limited to the multifunction device described in the embodiment and the printing system including the multifunction device, but is also applicable to a printing apparatus such as a printer and a printing system including the printing apparatus.
