Description

  The present invention relates to a program for controlling an information processing terminal to transmit a document being displayed to the outside.

  In recent years, with the increase of battery-driven information processing terminals such as notebook PCs (Personal Computers), smartphones, tablets, and the like, opportunities to browse documents on these information processing terminals have increased.

  Normally, if the battery runs out while a document is being viewed on a battery-driven information processing terminal, the browsing cannot be continued. Then, after the battery has run out, there is a problem that browsing of the document cannot be resumed until the battery is charged (or replaced).

  Incidentally, in recent years, it has been widely spread to send a print job from an information processing terminal to a printer. For example, in Cited Document 1, there is a method for suppressing the power consumption of its own terminal when the information processing terminal receiving an instruction from the user transmits a print job to the printer. A method for reliably transmitting a print job with a high priority even when the remaining battery level is low is disclosed.

JP 2006-244245 A JP 2006-82240 A

  If the printer that prints the document being viewed on its own terminal before the battery of its own terminal runs out, it is possible to continue browsing the document using the printed matter as an alternative medium even after the battery of its own terminal has run out. it can.

  Cited Document 1 and Cited Document 2 relate to a technique for transmitting a print job when the remaining battery level is low. Both of these are defined only for processing performed when a print job transmission instruction is received from a user. Therefore, if the battery of your terminal runs out without receiving an instruction to send a print job, for example, the battery runs out without the user noticing that the battery of your terminal is about to run out. It doesn't correspond to the case where it is closed.

  The present invention is intended to solve the above-described problem, and can continue browsing a document even when the battery runs out while the document is being viewed on an information processing terminal driven by a battery. An object of the present invention is to provide a program for controlling the information processing terminal.

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

[1] A program that is executed by a battery-powered information processing terminal that includes a communication unit, a display unit, and a storage unit that stores a document and an application program that opens and displays the document on the display unit. And
A confirmation step for confirming whether the application program is opening a document;
A remaining amount determining step for determining whether or not the remaining amount of electricity stored in the battery is less than a predetermined value;
When a document is opened by the application program and a remaining battery charge of the battery becomes less than the predetermined value, a print job for printing the document opened by the application program is transmitted to the outside. Sending step to
The program characterized by having.

  In the above-described invention, in the information processing terminal driven by the battery, when the remaining amount of power stored in the battery becomes less than a predetermined value, a print job for printing a document opened by the application program is transmitted to the outside. Thereby, even if the battery of the own terminal has run out, it is possible to continue browsing the document on another medium. Examples of the transmission destination of the print job include a printer, a printer box, a pull print server, and other display media capable of displaying the contents of the print job.

[2] The program according to [1], wherein in the transmission step, the print job is transmitted to an external printer.

[3] The printer includes a box for storing the received print job, and executes printing based on the print job designated by the output instruction when receiving the output instruction for the print job stored in the box. It has a box function,
The program according to [2], wherein in the transmission step, the print job is transmitted to the box of the printer.

  In the above invention, the information processing terminal transmits a print job to the printer box. The printer stores a print job received from the information processing terminal in a box, and executes printing based on the print job when receiving an output instruction for the print job. Since printing starts only after receiving an instruction (operation) from the user of the information processing terminal, the confidentiality of the document at the time of printing becomes higher than when printing is started immediately when the printer receives a print job. . When the user does not need to print the document, useless printing is not performed unless an output instruction is issued for the print job.

[4] In the transmission step, the received print job is stored, and the stored print job is transmitted to the external pull print server having a function of transmitting to the printer in response to a transfer request from the printer. The program according to [1], which transmits a print job.

  In the above invention, the user can execute the print job transmitted from the information processing terminal as long as the user can access the pull-print server as the transmission destination. As a result, the user can obtain a printed matter by using a printer that is relatively close. Further, when the user does not need to print the document, useless printing is not performed unless a transfer request is made.

[5] After the transmission step, when the charging of the battery is started, or when the battery is replaced with another battery whose remaining power is greater than a predetermined value, the stored print job is The program according to [3] or [4], further comprising a deletion step for deleting.

  In the above invention, when charging is started, or when the remaining amount of electricity stored exceeds a predetermined value due to battery replacement, it is possible to continue browsing the document on the information processing terminal. There is no need to execute the sent print job. If the user does not instruct execution, the print job remains in the destination box or pull print server for a long time. Therefore, the information processing terminal instructs the transmission destination of the print job to delete the print job when battery exhaustion is avoided.

[6] The program according to any one of [1] to [5], further including a transmission destination reception step of receiving designation of a transmission destination of the print job in the transmission step.

[7] A print range receiving step of receiving a print range specification in the document from the user,
The program according to any one of [1] to [6], wherein the print job is a print job for printing a print range designated in the print range reception step.

  In the above invention, since a print job designating only a part that the user wants to browse can be transmitted, it is possible to prevent unnecessary (unnecessary) parts from being printed.

[8] The remaining amount determining step detects a remaining amount of electricity stored in the battery,
The program according to [7], wherein in the print range reception step, the number of pages of a print job that can be completed with the detected remaining power storage amount is calculated and notified to the user.

  In the above invention, the number of pages of a print job that can be created and transmitted is calculated based on the remaining amount of power stored in the battery, and the number of pages obtained by the calculation is notified to the user. The user can prevent a situation where the battery runs out before the creation and transmission of the print job is completed by designating the print range so that the number of notified pages is equal to or less.

[9] In the print range reception step, one of the options including “all pages”, “pages after the currently displayed page”, “page specified by the user”, and “do not print” is selected. The program according to [7] or [8], wherein the print range is specified by being received.

  In the above invention, when “do not print” is selected, a print job is not created or transmitted.

[10] In the print range reception step, when the number of pages of the print job that can be completed with the detected remaining power storage amount is less than the total number of pages of the document, “user specifies [8] The program according to [8], wherein the print range is specified by receiving one of the selections including two options “page” and “not print”.

[11] The program according to any one of [1] to [10], wherein the application program is a viewing-only application program.

  When a document is opened with an application program that can also be edited, if the document that has not been edited is sent as a print job when the remaining battery charge becomes less than the specified value, the result is wasted. There is a possibility that. In the above invention, since the document is opened by a viewing-only application program, the above-mentioned problem does not occur.

[12] In the transmission step, when there are a plurality of documents opened by the application program, a plurality of documents opened by the application program when a remaining power storage amount of the battery becomes less than the predetermined value. A program according to any one of [1] to [11], wherein a print job for printing the document is sent to the outside.

  In the above invention, a print job is created and transmitted not only for a document being displayed but also for a document that is opened by an application program but is waiting on the background.

[13] In the transmission step, when it is determined in the remaining amount determining step that the remaining amount of power storage is less than a predetermined value, it is already closed but is opened by the application program within the past predetermined time. If there is a document that has been stored, a print job for printing the document is transmitted to the outside. The program according to any one of [1] to [12],

  In the above invention, since the document that has just been closed is likely to be opened again by the application program, even when there is no document open at that time when the remaining power is less than the predetermined value, If the elapsed time since the closing of one document opened by the application program is within a predetermined time, a print job for printing the document is transmitted to the outside.

[14] When the document is opened by the application program, there is further provided a necessary remaining amount calculating step of calculating a remaining amount of charge of the battery necessary for creating and transmitting a print job for all pages of the document. And
The program according to any one of [1] to [13], wherein, in the remaining amount determining step, the predetermined value is determined based on the remaining amount of power calculated in the required remaining amount calculating step. .

  In the above invention, when a document is opened by an application program, the amount of power required to create and send a print job for the document is calculated in advance, and a predetermined value determined based on the amount of power is calculated. When the remaining battery level is low, a print job for the document is created and transmitted. For example, if a value greater than the amount of power obtained by the above calculation is set to a predetermined value, a print job for all pages of the document is surely created when the remaining battery charge falls below the predetermined value. Can be sent.

  According to the program of the present invention, it is possible to continue browsing the document even when the battery runs out while the document is being browsed on the information processing terminal driven by the battery.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a printing system 7 according to an embodiment of the present invention. The printing system 7 is configured by communicably connecting a plurality of image forming apparatuses 10 (10A, 10B), an information processing terminal 40, and a server 60 through a network 3 such as a LAN (Local Area Network). . The image forming apparatuses 10 </ b> A and 10 </ b> B are collectively referred to as “image forming apparatus 10” when referring to an arbitrary unit.

  The information processing terminal 40 is a terminal such as a tablet that can be carried around, and is driven by a battery. The information processing terminal 40 includes a display unit 51 (see FIG. 2) described later, and stores a document and an application program that opens the document and displays the document on the display unit 51. The user can browse the document opened by the application program and displayed on the display unit 51. Further, the information processing terminal 40 can transmit a print job for printing the document to the image forming apparatus 10 or the server 60.

  The image forming apparatus 10 is a copy job that optically reads a document and prints a duplicate image on a recording paper, a scan job that stores image data of the read document as a file, or transmits the file to an external device, a PC, This is a so-called multi-function machine having a function of executing a job such as a print job for printing an image relating to data (print job) sent from the information processing terminal 40 on a recording paper, and as a printer in the present invention. To play a role. In the embodiment of the present invention, the image forming apparatus 10 includes a box for storing the received print job, and the print designated by the output instruction when receiving the output instruction for the print job stored in the box. It has a box function to execute printing based on jobs.

  The server 60 has a function of storing a print job received from the information processing terminal 40 and transmitting the stored print job to the image forming apparatus 10 in response to a transfer request from the image forming apparatus 10. This is a so-called pull print server.

  The program that controls the operation of the information processing terminal 40 plays a role as a program in the present invention. The information processing terminal 40 confirms whether or not the document is opened by the application program. When the document is opened by the application program and the remaining battery charge becomes less than a predetermined value, the application program A print job for printing a document opened by the program is transmitted to an external apparatus such as the image forming apparatus 10 or the server 60. Since the print job for printing the document being browsed before the battery of the terminal runs out is transmitted to the outside, the user continues to browse the document by the result of the print job even after the battery runs out can do.

  FIG. 2 is a block diagram showing a schematic configuration of the information processing terminal 40 according to the embodiment of the present invention. The information processing terminal 40 has a CPU (Central Processing Unit) 41 that comprehensively controls the operation of the information processing terminal 40. A CPU 41 including a microprocessor is connected to a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43, a nonvolatile memory 44, a remaining power storage detection unit 45, a network communication unit 46, and an operation display unit 50 through a bus. And. The information processing terminal 40 is driven by a battery (power supply unit 47).

  The CPU 41 is based on an OS (Operating System) program and executes middleware, application programs, and the like. In addition, the CPU 41 functions as a control unit that controls the display content of the display unit 51.

  In the embodiment of the present invention, the CPU 41 operated by the program of the present invention confirms whether or not the document is opened by the application program, and whether or not the remaining charge of the battery of its own terminal is less than a predetermined value. Control such as determination and transmission of a print job to the outside is performed.

  Various programs are stored in the ROM 42, and each function of the information processing terminal 40 is realized by the CPU 41 executing various processes according to these programs.

  The RAM 43 is used as a work memory for temporarily storing various data when the CPU 41 executes processing based on a program.

  The nonvolatile memory 44 is a memory (flash memory) whose stored contents are not destroyed even when the power is turned off, and is used for storing various setting information. The nonvolatile memory 44 stores an OS program, various application programs, documents, print jobs, a transmission history related to the print jobs, and the like.

  The network communication unit 46 functions to communicate data with the image forming apparatus 10 and the server 60 through the network 3. The embodiment of the present invention will be described as performing wireless communication using a wireless LAN, but the communication means is not limited to these.

  The remaining power storage detection unit 45 detects the remaining power storage of the power supply unit 47 (battery). The power source 47 (battery) can be charged via a power cord connected to the terminal itself. The battery may be replaceable.

  The operation display unit 50 includes a display unit 51 and an operation unit 52. Among these, the operation unit 52 includes a switch unit 53 such as a home button and a return button, and a touch panel unit 54. The display unit 51 is configured with a liquid crystal display (LCD) and the like, and has a function of displaying a document browsing screen, various operation screens, a setting screen, and the like. In the present embodiment, the CPU 41 performs control of display contents displayed by the operation display unit 50 and control related to reception of operations by the operation display unit 50.

  The touch panel unit 54 is provided on the display unit 51. The touch panel unit 54 detects a coordinate position on the display unit 51 pressed by a touch pen or a finger, a flick operation, a drag operation, and the like.

  FIG. 3 shows a flow of processing performed by the information processing terminal 40. First, the information processing terminal 40 checks whether or not a document is opened by an application program (step S101). If the document is not opened by the application program (step S101; No), the process returns to step S101 and continues.

  When the document is opened by the application program (step S101; Yes), it is checked whether or not the remaining amount of charge in the battery is less than a predetermined value (step S102). The predetermined value will be described later.

  If the remaining amount of power stored in the battery is greater than or equal to the predetermined value (step S102; No), the process returns to step S101 and continues. When the remaining amount of electricity stored in the battery is less than the predetermined value (step S102; Yes), the power consumption required for creating and transmitting a print job for printing all pages of the document opened by the application program is calculated. (Step S103).

  As a method for calculating power consumption, for example, it is obtained by integrating the power consumed by one page when creating a print job, the total power consumed by one page when transmitting a print job, and the number of pages of the document. The value is estimated as the aforementioned power consumption.

  If the calculated power consumption is less than or equal to the current battery charge level, the CPU 41 determines that a print job for printing all pages of the document can be created and transmitted (step S104: Yes). Then, a first message screen (see FIG. 4) described later is displayed on the display unit 51 (step S105), and the process proceeds to step S107. In the first message screen, a warning is given that the remaining battery charge is low, an instruction (selection) whether or not to print the document being viewed, and whether to print all pages when printing is performed. An instruction is received from the user, such as whether to print only the page.

  If the calculated power consumption exceeds the current battery charge level, the CPU 41 cannot create or send a print job for printing all pages of the document with the current battery charge level. It is determined that there is (step S104: No), a second message screen (see FIG. 5) described later is displayed on the display unit 51 (step S106), and the process proceeds to step S107. The second message screen warns that the remaining battery charge is low, instructs (selects) whether or not to print the document being viewed, and if printing is performed, prints with the current remaining battery charge. The print range is specified from the user within the maximum possible number of pages.

  In step S107, it is checked which one of the instruction to print on the first message screen or the second message screen and the instruction not to print is received. When an instruction not to perform printing is received (step S107; No), this process ends. When an instruction to perform printing is received (step S107; Yes), a print job for printing the print range designated with the instruction is created (step S108). The print job may be created in a format that matches the destination, or may be created in a preset fixed format. Thereafter, the print job is transmitted to the outside (step S109), and this process is terminated.

  An application program for opening a document includes a browsing-only program and a program that can edit the document (for editing). In FIG. 3, a document opened by any type of application program is a target for creation and transmission of a print job.

  If a document is opened and edited using an application program for editing, if an uncompleted document is sent as a print job when the remaining battery charge falls below a specified value, Since the result may be wasted, the type of the application program that is opening the document is judged, and only the document that is opened by the viewing application program is created and sent. It may be.

  Next, the first message screen and the second message screen will be described with specific examples. FIG. 4 shows an example of the first message screen. The first message screen is displayed when a print job for printing all pages of a document opened by the application program can be generated and transmitted with the current remaining battery charge.

  In the upper part of the first message screen, a warning that the remaining battery level of the battery of the terminal is low and a message for inquiring the user whether to print the document (file) being viewed are displayed. Further, below the message, a currently set print job transmission destination and a transmission destination change button 81 are displayed, and further below the four print range designation items 80, a page designation input field 82, and an OK button 83. Is displayed.

  The transmission destination change button 81 is an operation button that is pressed when changing the transmission destination of a print job. When the transmission destination change button 81 is pressed, the screen changes from the first message screen to another screen. The user can change the transmission destination of the print job on the screen after the transition.

In the embodiment of the present invention, the following three types can be selected as transmission destinations.
(1) Image forming apparatus 10 (immediate printing)
(2) Box of image forming apparatus 10 (3) Server 60

  When a print job is transmitted with (1) as a transmission destination, the image forming apparatus 10 of the transmission destination starts printing based on the received print job immediately after reception.

  When the print job is transmitted with (2) as the transmission destination, the print job is stored in the box of the image forming apparatus 10 of the transmission destination, and immediate printing is not performed. The user moves to the image forming apparatus 10 that is the destination of the print job (for example, the image forming apparatus 10A when the print job is transmitted to the image forming apparatus 10A), and is stored in the box of the image forming apparatus 10. When an output instruction is issued for a print job, the image forming apparatus 10 that has received the output instruction starts printing based on the print job specified by the output instruction.

  When the print job is transmitted with (3) as the transmission destination, the print job is stored in the server 60. When the user moves to one of the image forming apparatuses 10 (which may be either the image forming apparatus 10A or the image forming apparatus 10B) and is authenticated by the destination image forming apparatus 10, the image forming apparatus 10 prints to the server 60. A job transfer request is sent. In response to the transfer request, the server 60 transmits the corresponding print job to the image forming apparatus 10 that has transmitted the transfer request, and the image forming apparatus 10 that has received the print job starts printing based on the print job. In the case of (3), so-called pull printing is performed.

  When (2) or (3) is selected as the transmission destination, printing is executed in a state where the user is in front of the image forming apparatus 10 that is the output destination. Therefore, when (1) is selected as the transmission destination, that is, Compared to the case where the image forming apparatus 10 that has received the print job prints immediately, the possibility that a third party sees or takes away the document is reduced, and the security is improved.

  When (2) or (3) is the transmission destination, a retention period can be set. When the image forming apparatus 10 or the server 60 saves the print job and the print job based on the print job is not executed (or the print job is not transferred) and the storage period elapses, the print job Is automatically deleted.

  The print range designation item 80 is a print range option designated by the user. In the first message screen, four options of “print all pages”, “print pages after the open page”, “print by specifying pages”, and “do not print” are displayed as the print range designation item 80. Yes. The user selects one of the four options using a radio button arranged on the left side of the four options.

  When the information processing terminal 40 selects any one of the print range designation items 80 of “print all pages”, “print pages after the open page”, and “print by designating pages” as the print range, Determines that an instruction to execute printing has been received in step S107 of FIG. If the print range designation item 80 “not print” is selected, it is determined in step S107 in FIG. 3 that an instruction not to print is received.

  The page designation input field 82 is an input field for designating in detail the page to be printed when “print by designating page” is selected from the above-mentioned options. In the first message screen, the page designation input field 82 is displayed at the lower right of the print range designation item 80 of “designate page and print”.

  When the OK button 83 is pressed, the print range selected at that time and the setting of the transmission destination of the print job are confirmed, and the process proceeds to step S107 in FIG.

  FIG. 5 shows an example of the second message screen. The second message screen is displayed when the current remaining battery charge of the battery is insufficient to generate and send a print job for printing all pages of the document opened by the application program.

  On the second message screen, similar to the first message screen, a warning that the battery charge of the terminal's battery is low and a message for inquiring the user whether to print the document (file) being viewed are displayed. Is done. Further below that, a transmission destination of the currently set print job and a transmission destination change button 91 are displayed, and further below that, two print range designation items 90, a page designation input field 92, and an OK button 93 are displayed. .

  The transmission destination change button 91 is an operation button having the same role as the transmission destination change button 81 shown in FIG. The destinations that can be set on the second message screen are the same as the destinations that can be set on the first message screen.

  The print range designation item 90 is a print range option designated by the user. In the second message screen, two options of “designate page and print” and “do not print” are displayed as print range designation items 90. The user selects one of the two options using a radio button arranged on the left side of the two options.

  When the print range designation item 90 of “do not print” is selected as the print range on the second message screen, the information processing terminal 40 determines that an instruction not to print is received in step S107 of FIG. When the print range designation item 90 of “print by specifying page” is selected, it is determined that an instruction to perform printing has been received in step S107 of FIG.

  The page designation input field 92 is an input field for designating in detail the page to be printed when “print by designating page” is selected from the above-mentioned options. In the second message screen, the page designation input field 92 is displayed at the lower right of the print range designation item 90 of “designate page and print”.

  In the second message screen, the maximum number of pages that can be printed with the current remaining battery charge amount is displayed on the right side of the print range designation item 90 of “designate page and print”. In 92, each page to be printed can be arbitrarily designated within a range in which the total number of pages to be printed falls within the maximum number of printable pages displayed. If an amount of pages that exceeds the maximum number of displayed pages is specified, this is notified and prompts for resetting.

  When the OK button 93 is pressed, the print range selected at that time and the setting of the transmission destination of the print job are confirmed, and the process proceeds to step S107 in FIG.

  In this way, in the information processing terminal 40, when the remaining amount of electricity stored in the battery becomes less than a predetermined value, a print job for all pages of the document opened in the application program is created and transmitted with the remaining amount of electricity stored. Whether to display the first message screen or the second message screen is switched depending on whether or not it is possible. In the second message screen, the total number of printable pages that can be set is limited to the maximum number of pages that can be generated and transmitted with the remaining amount of electricity stored.

  Next, a case where charging of the battery of the information processing terminal 40 is started after transmission of the print job but before printing based on the print job is started will be described.

  When the transmission destination of the print job is the box of the image forming apparatus 10 or the server 60, the user operates the image forming apparatus 10 until the storage period set at the time of transmission of the print job elapses (see above). The print job is held at the transmission destination of the print job until an output instruction or a transfer request transmission instruction is issued.

  If charging of the battery is started before the printing based on the print job is started after the transmission of the print job, the information processing terminal 40 can continue browsing the document. No output is required. Therefore, in such a case, the information processing terminal 40 transmits an instruction to delete the print job to the transmission destination of the print job. As a result, the print job transmission destination can quickly delete the print job when the print job is no longer needed. In addition, when the retention period is not set when the print job is transmitted, the print job is prevented from remaining indefinitely without being executed.

  FIG. 6 shows processing until the information processing terminal 40 transmits an instruction to delete the print job to the transmission destination of the print job. First, when charging of the battery is started in a state where the remaining battery charge is less than a predetermined value (step S201; Yes), a print job is sent to the box of the image forming apparatus 10 or the server 60 due to the battery running out. Is checked (step S202). If it is not transmitted (step S202; No), this process is terminated. When the print job is transmitted with the box or the server 60 of the image forming apparatus 10 as the transmission destination (step S202; Yes), the transmission destination of the print job is instructed to delete the print job being stored (step S202). S203), the process is terminated. Even when the battery has run out without starting charging (step S201; No), this process ends.

  In FIG. 6, deletion of a print job is instructed without confirming whether or not the print job is being stored in the box of the image forming apparatus 10 and the server 60, but the print job transmission destination receives the instruction. Whether or not the print job is still stored may be confirmed, and deletion of the print job may be instructed only when the print job is being stored.

  Next, the process performed by the information processing terminal 40 will be described with a plurality of modified examples.

(Modification 1, when multiple documents are opened)
In the first modification, a case where there are a plurality of documents opened by an application program will be described. For example, when there is a document waiting in the background separately from the document being displayed, two or more documents are opened by the application program.

  When there are a plurality of documents opened by the application program when the remaining amount of power stored in the battery is less than a predetermined value, the information processing terminal 40 transmits a print job for printing all of them to the outside.

  Although one print job for printing all of a plurality of documents opened by the application program may be created and transmitted, in the embodiment of the present invention, a print job is created and transmitted for each document. Shall. For example, when the remaining amount of power stored in the battery is less than a predetermined value, if there are three documents opened by the application program, the information processing terminal 40 creates and transmits three print jobs.

  Note that, for each document to be transmitted, whether or not to print from the user, and when printing, the print range may be accepted. For example, the first message screen or the second message screen described with reference to FIGS. 4 and 5 is displayed for each document so that the print range is designated.

  If there are multiple documents to be sent, determine whether it is possible to create and send a print job for all pages with the remaining power remaining in the battery immediately before receiving a print range specification for each document. In accordance with the determination result, the first message screen or the second message screen is switched.

  For example, when there are three documents to be transmitted, first, in the first document, it is determined whether a print job for all pages can be created and transmitted with the remaining power remaining in the battery. Switching between displaying the first message screen and displaying the second message screen according to the determination result. In the second document, the remaining power obtained by subtracting the power (predicted value) required for the creation and transmission of the print job related to the first document from the remaining power storage amount remaining in the battery is used. It is determined whether or not a print job for all pages of the document can be created and transmitted, and whether to display the first message screen or the second message screen is switched according to the determination result. In the third document, the remaining power obtained by subtracting the power (predicted value) required for the creation and transmission of the print job related to the first and second documents from the remaining power remaining in the battery, It is determined whether a print job for all pages of the third document can be created and transmitted, and whether to display the first message screen or the second message screen is switched according to the determination result.

  When a plurality of documents are opened, for example, the print range is specified from the youngest one viewed last, and a print job is created and transmitted. Priorities may be determined in advance, and a print range may be designated according to the priorities, and a print job may be created and transmitted.

(Modification 2, if there is a document that has just been closed)
There is a high possibility that the user resumes browsing a document with a short elapsed time since being closed. Therefore, the information processing terminal 40 creates a print job for printing a document when the remaining battery charge is less than a predetermined value and there is a document whose elapsed time from the closing is within a predetermined time. Send it to the outside.

  If there is a document opened by the application program and a document whose elapsed time has been within a predetermined time since the document was closed, a print job may be created for both, or the document may be opened by the application program. A print job may be created with priority given to existing documents. In the latter case, for example, if the remaining battery charge remains even after creating and sending a print job for a document opened by an application program, the document that has elapsed since it was closed is within a specified time. Also create and send print jobs.

(Modified example 3, predetermined value of remaining power)
In FIG. 3, when the remaining amount of power stored in the battery is less than a predetermined value, a print job is designated and a print job is transmitted. The value of the predetermined value may be set by the user, It may be a fixed value determined in advance. Further, when a document is opened by an application program, power required for creating and transmitting a print job for printing all pages of the document is calculated, and a predetermined value is determined based on the calculated value. Also good. The predetermined value is determined so that the calculated value ≦ the predetermined value. For example, if the calculated value <predetermined value, when the remaining battery charge falls below a predetermined value, the print job for all pages of the document opened by the application program is displayed using the remaining stored power. Can be created and sent.

  As described above, in the embodiment of the present invention, the information processing terminal 40 prints a document that has an open application program when the remaining amount of charge in the battery falls below a predetermined value. Is created and transmitted to the outside (the image forming apparatus 10 or the server 60). Thereby, even after the battery runs out, it is possible to continue browsing the document on the printed paper medium.

  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.

  In the embodiment of the present invention, a process for checking whether there is a print job that has been transmitted to a box or the like and transmitting an instruction to delete the print job to the destination of the print job if there is a corresponding print job is performed to the battery. Although the example of performing when the charging of the battery is started has been shown, the same processing is performed not when the charging is started but when the battery is replaced with a new one (or a battery whose remaining power is greater than a predetermined value). You may make it perform.

  In the embodiment of the present invention, a print job is transmitted to an external device via a network 3 such as a wireless LAN, but the communication format is not limited to this. For example, Bluetooth (registered trademark) or infrared rays may be used. The print job may be transmitted using a communication method such as P2P (Peer to Peer).

  In the embodiment of the present invention, the print job is created after the remaining amount of power stored in the battery becomes less than a predetermined value. However, the creation timing of the print job is not limited to this. For example, when a document is opened by an application program, a print job for the document may be created in advance. If a print job is created in advance while there is a sufficient remaining battery charge, a print job for all pages can be created reliably.

  In the embodiment of the present invention, the information processing terminal 40 receives the designation of the transmission destination of the print job, but the transmission destination may be fixed in advance.

  Printing that prints only the pages after the open page of the open document, which is not enough power to create and send a print job to print all pages of the open document. When there is a remaining amount of electricity that can be used to create and send a job, an option “print pages after the open page” may be displayed in the print range designation item 90 of the second message screen.

  Also, if there is not enough power remaining to create and send a print job that prints all pages of an open document, for example, color documents are printed in black and white, photos and images are omitted Alternatively, a print job may be created by a method that reduces power consumption without cutting pages, such as reduced printing, Nin1 printing, or the like.
