JP6745030B2 - Program for responding to running out of battery while browsing - Google Patents

Description

The present invention relates to a program for controlling an information processing terminal so that a displayed document is transmitted to the outside.

In recent years, with the increase in battery-powered information processing terminals such as notebook PCs (Personal Computers), smartphones, tablets, etc., there are increasing opportunities to browse documents on these information processing terminals.

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

By the way, in recent years, transmitting a print job from an information processing terminal to a printer has generally become widespread. For example, in the cited document 1, a method for suppressing power consumption of the information processing terminal when the information processing terminal instructed by the user sends a print job to the printer, and in the cited document 2, the information processing terminal is the printer. There is disclosed a method for surely transmitting a print job having a high priority even when the battery level is low when the print job is transmitted to.

JP, 2006-244245, A JP 2006-82240 A

If the printer is allowed to print the document that is being browsed by the terminal before the battery of the terminal is depleted, the document can continue to be browsed using the printed material as a substitute medium even after the battery of the terminal is depleted. it can.

The cited document 1 and the cited document 2 relate to a technique for transmitting a print job when the battery level is low. However, all of these stipulate only the process to be performed when a print job transmission instruction is received from the user. Therefore, if the battery of your own terminal runs out without receiving a print job transmission instruction, for example, the battery of your own terminal is running out without you being aware that it is about to run out of battery. It does not correspond to cases such as accidents.

The present invention is intended to solve the above problems, and while a document is being browsed on a battery-powered information processing terminal, the document can be continuously browsed even if the battery runs out. The purpose is to provide a program for controlling the information processing terminal.

The gist of the present invention for achieving such an object resides in the inventions of the following items.

[1] A program executed by a battery-powered information processing terminal, which includes a communication unit, a display unit, and a storage unit that stores a document and an application program for opening the document and displaying the document on the display unit. hand,
A confirmation step for confirming whether the application program has a document open,
A remaining amount determination step of determining whether or not the remaining charge of the battery is less than a predetermined value,
When a document is opened by the application program and a remaining 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. A sending step to
The destination of the print job saves the received print job in a box, and when receiving the output instruction for the print job saved in the box, executes printing based on the print job specified by the output instruction. An external pull print having a function of storing the above-mentioned box of a printer having a box function or a received print job and transmitting the stored print job to the printer in response to a transfer request from the printer. In the server, after the transmitting step, when the charging of the battery is started, or when the battery is replaced with another battery whose remaining charge is higher than a predetermined value, the data is stored in the destination. A delete step for deleting the print job
A program characterized by having.

In the above invention, the information processing terminal driven by the battery transmits the print job for printing the document opened by the application program to the outside when the remaining charge of the battery becomes less than the predetermined value. As a result, even if the battery of the terminal itself is dead, it is possible to continue browsing the document on another medium. Examples of the destination of the print job include a printer, a printer box, a pull print server, and another display medium capable of displaying the content of the print job.
Further, in the above invention, the information processing terminal transmits the print job to the printer box or the pull print server. When the destination is a box, the printer saves the print job received from the information processing terminal in the box and executes printing based on the print job when receiving the 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 starts immediately when the printer receives a print job. .. When the user does not need to print the document, wasteful printing is not performed unless the user issues an output instruction for the print job. If the destination is the pull print server, the user can execute the print job transmitted by the information processing terminal if the user can access the destination pull print server. As a result, the user can obtain the printed matter by using the printers located relatively near. If the user does not need to print the document, wasteful printing is not performed unless a transfer request is made.
Further, in the above invention, when the charging is started or the state of the remaining charge exceeds the predetermined value due to the battery replacement, the document can be continuously viewed on the information processing terminal, so that the box or pull print server can be continued. It becomes unnecessary to execute the print job sent to. If the user does not instruct execution start, the print job remains held 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 the battery exhaustion is avoided.

In the present embodiment, the CPU 41 controls the display content displayed by the operation display unit 50 and the control regarding the acceptance of the operation 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, or the like.

FIG. 3 shows a flow of processing performed by the information processing terminal 40. First, the information processing terminal 40 confirms whether or not the document is opened by the application program (step S101). When 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 the remaining charge of the battery is less than a predetermined value (step S102). The predetermined value will be described later.

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

The power consumption is calculated, for example, by adding up the power consumed by one page when a print job is created, the power consumed by one page when a print job is transmitted, and the number of pages of a document. The value is roughly estimated as the above power consumption.

When the calculated power consumption is less than or equal to the current remaining charge of the battery, the CPU 41 determines that it is possible to create and transmit a print job for printing all pages of the document (step S104: Yes). 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. Note that the first message screen warns that the remaining battery charge is low, gives an instruction (selection) whether to print the document being viewed, and specifies whether to print all pages when printing. The user receives an instruction to print only the page.

If the calculated power consumption exceeds the current remaining charge of the battery, the CPU 41 cannot create or transmit a print job for printing all pages of the document with the current remaining charge of the battery. It is determined that there is (step S104: No), the second message screen (see FIG. 5) described later is displayed on the display unit 51 (step S106), and the process proceeds to step S107. Note that the second message screen warns that the remaining battery charge is low, gives an instruction (selection) as to whether or not to print the document being viewed, and prints with the current remaining charge when printing. A user specifies the print range within the maximum number of pages possible.

In step S107, it is checked whether the instruction to print or the instruction not to print is received on the first message screen or the second message screen. When the instruction not to print is received (step S107; No), this processing ends. When the instruction to print is received (step S107; Yes), a print job for printing the print range designated together with the instruction is created (step S108). The print job may be created in a format suitable for the destination, or may be created in a fixed format set in advance. After that, the print job is transmitted to the outside (step S109), and this processing ends.

The application programs for opening a document include those for reading only and those for editing the document (for editing). In FIG. 3, a document opened by any type of application program is targeted for print job creation and transmission.

If you open a document with an editing application program and edit it, if you send an uncompleted document as a print job when the remaining battery charge falls below a specified value, The result may be wasted, so determine the type of application program that has the document open, and make only the document opened with the application program for viewing the target for creating and sending print jobs. You can

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 it is possible to generate and send a print job for printing all pages of the document opened by the application program with the current remaining charge of the battery.

At the upper part of the first message screen, a warning that the remaining charge of the battery of the terminal is low and a message asking the user whether to print the document (file) being viewed are displayed. Further, below the message, the currently set destination of the print job and the 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 destination change button 81 is an operation button that is pressed when changing the destination of a print job. When the destination change button 81 is pressed, the first message screen is changed 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 the destination.
(1) Image forming apparatus 10 (immediate printing)
(2) Box of image forming apparatus 10 (3) Server 60

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

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 that is the transmission destination, and immediate printing is not performed. The user moves to the image forming apparatus 10 to which the print job is transmitted (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 given to a print job that is present, 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 the image forming apparatus 10A or the image forming apparatus 10B) and the user is authenticated by the image forming apparatus 10 of the moving destination, the image forming apparatus 10 prints on 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 is the transmission source of the transfer request, and the image forming apparatus 10 that receives 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 destination, printing is executed in the 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 destination, that is, As compared with the case where the image forming apparatus 10 that receives a print job immediately prints, the possibility that a document is viewed or carried away by a third party is reduced, and security is improved.

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

The print range designation item 80 is a print range option designated by the user. On the first message screen, as print range specification item 80, four options of "print all pages", "print pages after open page", "print by specifying page", and "do not print" are displayed. There is. The user selects one of the four options using the radio buttons located to the left of the four options.

In the information processing terminal 40, when the print range specification item 80 is selected from among “print all pages”, “print page after open page”, and “print by specifying page” as the print range. Determines that it has received an instruction to execute printing in step S107 of FIG. When the print range designation item 80 of "not print" is selected, it is determined in step S107 of FIG. 3 that the instruction not to print is received.

The page designation input field 82 is an input field for detailedly designating a page to be printed when “designate page and print” is selected from the above-mentioned options. On 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 and print page”.

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

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

Similar to the first message screen, the second message screen displays a warning that the remaining battery charge of the terminal is low and a message asking the user whether to print the document (file) being viewed. To be done. Further below, a currently set destination of the print job and a destination change button 91 are displayed, and further below, two print range designation items 90, a page designation input field 92, and an OK button 93 are displayed. ..

The destination change button 91 is an operation button having the same role as the 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. On the second message screen, as print range designation item 90, two options of "designate page and print" and "do not print" are displayed. The user selects one of the two choices using the radio button located to the left of the two choices.

When the print range designation item 90 of "not print" is selected as the print range on the second message screen, the information processing terminal 40 determines that the instruction not to print is received in step S107 of FIG. When the print range designation item 90 of "designate page and print" is selected, it is determined that an instruction to print is received in step S107 of FIG.

The page designation input field 92 is an input field for detailedly designating a page to be printed when “designate and print page” is selected from the above-mentioned options. On 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 and print page”.

In the second message screen, the maximum number of pages that can be printed with the current remaining charge of the battery is displayed on the right side of the print range designation item 90 of “Specify and print page”. 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 the specified number of pages exceeds the maximum number of pages displayed, a notification to that effect is given and the setting is urged again.

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

As described above, in the information processing terminal 40, when the remaining charge of the battery becomes less than the predetermined value, the print jobs for all pages of the document opened by the application program are created and transmitted with the remaining charge. Whether to display the first message screen or the second message screen is switched depending on whether it is possible or not. On 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 charge level.

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

When the 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 transmitting the print job elapses or the user operates the image forming apparatus 10 (described above). The print job is held at the transmission destination of the print job until the output instruction of (1) or the transmission instruction of the transfer request is performed.

If the battery is charged after the print job is transmitted and before the printing based on the print job is started, the document can be continuously browsed by the information processing terminal 40, so that the document can be read on the paper medium. Output is unnecessary. Therefore, in such a case, the information processing terminal 40 transmits an instruction to delete the print job to the destination of the print job. As a result, the transmission destination of the print job can immediately delete the print job when the print job is no longer needed. Further, when the retention period is not set when the print job is transmitted, the print job is prevented from being left without being executed.

FIG. 6 shows a process until the information processing terminal 40 transmits an instruction to delete the print job to the destination of the print job. First, when charging of the battery is started when the remaining charge of the battery is less than the 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 exhaustion. Is transmitted (step S202). If it has not been transmitted (step S202; No), this processing ends. When the print job is transmitted with the box of the image forming apparatus 10 or the server 60 as the destination (step S202; Yes), the destination of the print job is instructed to delete the print job that is being saved (step S202). (S203), this process ends. Even if the battery runs out without being charged (step S201; No), this processing ends.

In FIG. 6, the print job is instructed to be deleted without confirming whether the print job is being saved in the box of the image forming apparatus 10 and the server 60. It may be possible to confirm whether or not the print job is still stored and to instruct to delete the print job only when the print job is being stored.

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

(Modification 1, when multiple documents are open)
In the first modification, a case where there are a plurality of documents opened by the application program will be described. For example, if there is a document waiting in the background in addition to the document being displayed, it means that two or more documents are opened by the application program.

The information processing terminal 40 transmits a print job for printing all of the documents opened by the application program to the outside when the remaining charge of the battery is less than the predetermined value and when there are a plurality of documents opened by the application program.

Although one print job for printing all the documents opened by the application program may be created and sent, in the embodiment of the present invention, a print job is created and sent for each document. I shall. For example, when the remaining charge of the battery is less than the predetermined value and the number of documents opened by the application program is three, the information processing terminal 40 creates and transmits three print jobs.

It should be noted 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, and the print range is designated.

If there are multiple documents to be sent, immediately before the print range is specified for each document, it is determined whether or not it is possible to create and send a print job for all pages with the remaining charge level in the battery. , The first message screen or the second message screen is switched according to the determination result.

For example, when there are three documents to be transmitted, first, in the first document, it is determined whether or not it is possible to create and transmit a print job for all pages with the remaining charge in the battery. The first message screen or the second message screen is switched according to the determination result. In the second document, the remaining power obtained by subtracting the power (predicted value) required for creating and transmitting the print job related to the first document from the remaining power remaining in the battery is used as the second power. It is determined whether or not print jobs for all pages of the document can be created and transmitted, and the display of 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 creating and transmitting the print jobs 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 the first message screen or the second message screen is displayed 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. It is also possible to determine the priority order in advance, receive the designation of the print range according to the priority order, and create and transmit the print job.

(Modification 2, when there is a document that has just been closed)
Documents that have been closed for less time are likely to be resumed by the user. Therefore, the information processing terminal 40 creates a print job for printing the document when the remaining amount of the battery is less than the predetermined value and there is a document whose elapsed time after the closing is within the predetermined time. And send it to the outside.

If there is a document that is opened by the application program and a document that has been closed for less than the specified time, a print job may be created for both of these documents, or it may be opened by the application program. The print job may be created by giving priority to the document that exists. In the latter case, for example, if the remaining charge of the battery still remains after creating/transmitting a print job related to the document opened by the application program, the document that has passed since the closing time is within the specified time Also creates and sends a print job.

(Modified Example 3 Regarding Predetermined Value of Remaining Power Storage)
In FIG. 3, when the remaining charge of the battery is less than the predetermined value, the print job is specified and the print job is transmitted, but the predetermined value may be set by the user. It may be a fixed value determined in advance. When a document is opened by an application program, the power required to create and send a print job for printing all pages of the document is calculated, and a predetermined value is determined based on the calculated value. Good. The predetermined value is determined so that the calculated value≦the predetermined value. For example, if the calculated value is smaller than the predetermined value, when the remaining charge of the battery falls below the predetermined value, the print jobs for all pages of the document opened by the application program are stored with the remaining stored power. You can always create and send.

As described above, in the embodiment of the present invention, the information processing terminal 40 prints the document if the application program is open when the remaining battery charge is less than the predetermined value. Print job is created and transmitted to the outside (the image forming apparatus 10 or the server 60). As a result, even after the battery runs out, it is possible to continue browsing the document on the printed paper medium.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configurations are not limited to those shown in the embodiments, and there are changes and additions within the scope not departing from the gist of the present invention. Also included in the present invention.

In the embodiment of the present invention, the process of checking the presence or absence of 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 to the destination of the print job is sent to the battery. Although the example was performed when the charging of the battery is started, the same processing is performed not only when the charging is started but also when the battery is replaced with a new battery (or a battery whose remaining charge is more than a predetermined value). It may be executed.

In the embodiment of the present invention, the print job is transmitted to the external device via the network 3 such as a wireless LAN, but the communication format is not limited to this. For example, Bluetooth (registered trademark) or infrared 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 charge of the battery becomes less than the predetermined value, but the print job creation timing 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 the print job is created in advance while the remaining charge of the battery is sufficient, the print jobs for all pages can be created with certainty.

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

Note that there is not enough power remaining to create and send a print job to print all pages of an open document, but only the pages after the open page of the open document are printed. If there is enough remaining power to create and send a job, the option “print pages after the opened page” may be displayed in the print range specification item 90 on the second message screen.

If there is not enough power remaining to create and send a print job to print all pages of an open document, for example, color documents are printed in monochrome, photos and images are omitted. A print job may be created by a method of reducing power consumption without scraping a page, such as reduction printing, Nin1 printing, or the like, and such an option may be provided.
