Description

  The present invention relates to deferred printing in which printing is performed based on a print job after a print job is received and a print instruction for the print job is received.

  There is a printing device that receives a print job from an external device, holds the print job until a print execution instruction is input on the operation panel, and executes printing based on the print job after the print execution instruction is input on the operation panel (Patent Document 1). In this printing apparatus, after storing print jobs, the user can specify color printing and change the number of copies on the operation panel.

JP2012-223891

  There are two types of printing systems. In the first printing system, a printer driver installed in an external device such as a PC generates a print job and transmits the print job to the printing device. In the second printing system, an external device such as a smart phone or a tablet terminal instructs the print service to print a file, the print service generates a print job according to the instruction, and transmits the print job to the printing device. In the second printing system, the external device does not require a printer driver, and various types of files can be printed without the printer driver.

  While the second printing system can perform printing without a printer driver, print settings that can be specified by the printer driver may not be specified by the print service. In this case, the user cannot use print settings that can be specified by the printer driver, and cannot perform printing with the print settings originally intended by the user.

  A conventional printing apparatus reserves a print job issued from such a print service and waits for the user to specify print settings that cannot be specified in the print service on the operation panel, so that the user cannot specify in the print service. Made print settings available. Thereby, the convenience for the user is improved.

  However, in a conventional printing apparatus, when a function for holding a print job (hereinafter referred to as hold printing) is used, all print jobs are held. For this reason, print jobs of users who do not want to use reserved printing are also reserved.

  Some printer drivers can specify reservation printing. However, when the printing apparatus holds only a print job for which reserved printing is designated, the print job issued from the print service as described above cannot be held. That is, all print jobs can be reserved, or only print jobs for which reserved printing is designated can be reserved.

  Therefore, according to the present invention, even when a print job for which reservation printing is not designated is received, reservation printing can be performed depending on the print job, or printing can be performed without leaving the print job. . Alternatively, the print job can be executed after receiving the print setting input or the print job can be executed without waiting for the print setting input.

The image forming apparatus according to the present invention holds a print job that is a received print job and is set as a print job setting in a storage area, and holds the print job in response to receiving a print instruction via the operation unit. set in the image forming apparatus capable of executing the reservation printing and executes printing of the print job is placed, whether retain it performs Tomeoki of print jobs that are not set as the setting for the print job as the setting of the image forming apparatus Setting means for storing, storage means for storing a reservation condition used for specifying whether a print job that is not set to be reserved as a print job setting is the target of the reservation, and performing the reservation by the setting means and there When set as the setting of the image forming apparatus, the setting of the print job to a print job received And control means that controls whether retain before Symbol storage area based on the set the print jobs not Tomeoki conditions retain, the print setting used for printing the print job detained in the storage area characterized by chromatic and accepting means for accepting designation through the operation unit.

  In the present invention, even when a print job for which reservation printing is not designated is received, reservation printing can be performed depending on the print job, or printing can be performed without leaving the print job. Alternatively, the print job can be executed after receiving the input of the print setting, or the print job can be executed without waiting for the input of the print setting.

<First Embodiment>
Embodiments will be described with reference to the drawings. In the following, an MFP (multifunction peripheral) will be described as an example of a printing apparatus. The printing apparatus may be an SFP (Single Function Peripheral) that has a printing function but does not have a copying function.

  FIG. 1 is a diagram illustrating a hardware configuration of the MFP 100. The MFP 100 includes a controller unit 101, a printing unit 106, a reading unit 108, an operation panel 110, and a power supply unit 111. The controller unit 101 includes a CPU 102, a RAM 103, a ROM 104, a printing unit interface 105, and a reading unit interface 107. Further, the controller unit 101 includes a power control unit 109, a fax unit 112, a network interface 113, a system bus 114, and a hard disk drive (HDD) 117. The devices 102, 103, 104, 105, 107, 109, 112, 113, 117 are connected to the system bus 114.

  The CPU 102 comprehensively controls the printing apparatus according to various control programs. The ROM 104 stores various control programs. The CPU 102 reads a control program from the program area of the ROM 104 to the RAM 103 and executes the control program stored in the RAM 103. When the compressed control program is stored in the ROM 104, the CPU 102 expands the compressed control program, stores the expanded control program in the RAM 103, and executes it. A control program executed by the CPU 102 may be stored in a hard disk drive (HDD) 117. The ROM 104 is a nonvolatile memory such as a flash ROM, and can retain data even when the power to the ROM 104 is turned off. There may be no HDD 117 depending on the type of printing apparatus.

  The printing unit interface 105 is an interface for outputting an image signal to the printing unit 106. The reading unit interface 107 is an interface for inputting an image signal from the reading unit 108. When the copy function is executed, the CPU 102 processes the image signal input from the reading unit 108 via the reading unit interface 107 and outputs the image signal for printing to the printing unit 106 via the printing unit interface 105. Output. The printing unit 106 prints an image based on the image signal on a sheet. The reading unit 108 reads an image on a sheet and generates an image signal corresponding to the image.

  The power supply unit 111 supplies power to the printing unit 106, the reading unit 108, the power control unit 109, and the operation panel 110. The power control unit 109 receives power from the power supply unit 111 and supplies power to each device of the controller unit 101 via a power line (not shown).

  The fax unit 112 performs facsimile communication with an external device (for example, a facsimile device) connected to the telephone line 115. For example, the fax unit 112 transmits image data to an external device via the telephone line 115. The fax unit 112 also receives image data from an external device via the telephone line 115.

  The network interface 113 is connected to the network 116 and performs network communication with an external device (for example, a personal computer, a smartphone, a tablet terminal, etc.) via the network 116. The network 116 is 10BASE-T, 100BASE-T, token ring, or the like. In the present embodiment, the network interface 113 receives a print job from an external device via the network 116. Various protocols such as HTTP, IPP, LPR, RAW, and WSD are used for communication with an external device. A wireless technology such as a wireless LAN or WiFi may be used.

  FIG. 2 is a diagram illustrating a hardware configuration of the operation panel 110. The operation panel 110 includes function keys 201 to 204 for selecting functions such as copying, FAX, scanning, and reserved printing. The user presses the function key corresponding to the function to be used. The display unit 205 notifies the user of the setting state and the device state. Arrow keys 206 are buttons corresponding to up, down, left, and right, respectively. An OK key 207 is a button for instructing determination regarding a setting or an inquiry. A number key 208 is a button for inputting a number. Since the other keys shown in FIG. 2 are not used in this embodiment, their description is omitted. A start key 209 is a button for instructing execution of a job.

  For example, when the user changes the copy function setting, the user first presses the function key 201. When the function key 201 is pressed, the display unit 205 displays a copy function screen. The user presses an arrow key 206 to select a setting item (for example, paper size) to be changed, and presses an OK key 207. When the OK key 207 is pressed, the display unit 205 displays a setting screen for selecting a setting value. The user presses the arrow key 206, selects a desired setting value (for example, A3), and presses the OK key 207. Then, the setting value selected by the user is set as the copy function setting. The user presses the start key 209 when instructing the start of copying.

  Hereinafter, a print control process performed by MFP 100 will be described. In the present embodiment, the MFP 100 has a function of holding a print job. Keeping a print job means that a print job is stored in a storage unit such as the RAM 103 or the HDD 117 until a print instruction from the user is input on the operation panel 110, and the print job is input after the print instruction is input on the operation panel 110. Based printing. Hereinafter, this function is referred to as reservation printing, and the MFP 100 can execute reservation printing.

  FIG. 3 is a flowchart illustrating print control processing according to the first embodiment. The print control process is executed by the CPU 102 executing the control program.

  When the network interface 113 receives a print job from an external device via the network, the CPU 102 receives the print job via the network interface 113 (S301). In the first embodiment, the protocol used to receive a print job may be unique or general purpose. When the print job is received, the CPU 102 analyzes the job information of the print job and determines the type of the print job (S302).

  The print job includes print data to be printed and job information. The job information includes a job ID, a user name (job owner) who transmitted the job, a job type, a job size, print settings for printing print data, and the like. Job types include PC print and cloud print. Although the type of job may identify the type of language used in the print job, in this embodiment, the type of language used in the print job is omitted.

  “PC print” indicates a print job generated by a printer driver installed in an external device such as a personal computer. The printer driver displays a user interface screen on a display device of an external device, and the user can specify various print settings on the user interface screen. The printer driver generates a print job including print settings designated by the user, an identifier indicating PC printing, and print data, and transmits the print job to MFP 100.

  “Cloud print” indicates a print job issued from a cloud service. In cloud printing, an external device such as a smartphone or a tablet terminal accesses the cloud service and instructs the cloud service to print a desired file. The cloud service is provided by an external device such as a server computer. The cloud service generates a print job including a print setting designated by the user, an identifier indicating the cloud print, and a file designated by the user (or print data generated from the file). Send to MFP 100. The print job generated by the cloud service may be transmitted directly from the cloud service to the MFP 100 or may be transmitted from the cloud service to the MFP 100 via an external device such as a smartphone or a tablet terminal. The file specified by the user may be stored in the cloud service server, or may be stored in an external device such as a smartphone or a tablet terminal. When the file is stored in an external device such as a smartphone or a tablet terminal, the external device transmits the file to the cloud service server. Even in cloud printing, the user can specify desired print settings.

  In the present embodiment, there are two types of print jobs, “PC print” and “cloud print”, but other types of print jobs may exist. For example, “WiFi Direct Print” indicates a print job transmitted from an external device such as a smartphone or a tablet terminal using WiFi.

  In the present embodiment, the number of print setting items that can be set by cloud printing is smaller than the number of print setting items that can be set by the printer driver. Some of the print settings that can be specified by the printer driver cannot be specified by cloud print.

  In the present embodiment, it is assumed that only four items of Nin1 (a layout in which N pages are allocated to one sheet), single-sided printing / double-sided printing, number of copies, and monochrome printing / color printing can be set in cloud printing. The printer driver can specify four items, Nin1, single-sided / double-sided printing, number of copies, monochrome / color printing, as well as two types of finishing (stapling, sorting, bookbinding, etc.) and paper type used for printing. Assume that

  After the type of print job is determined, the CPU 102 determines whether the function for forcibly holding the print job is enabled (S303). The function for forcibly holding a print job is to determine whether or not to hold a print job based on a table to be described later and to hold a predetermined type of print job. In the present embodiment, the user selects in advance on the operation panel 110 whether or not to enable the function of forcibly holding a print job. When the function is selected to be valid, a setting value indicating that the function is valid is stored in the RAM 103 or the HDD 117. The CPU 102 refers to the set value and determines whether the function for forcibly holding the print job is enabled. If the function of forcibly holding a print job is enabled, a print job that is not designated to hold a print job is also held.

  If the function for forcibly holding the print job is not enabled, the CPU 102 performs printing based on the print setting included in the print job without waiting for a print instruction from the user to be input on the operation panel 110. The printing unit 106 is controlled to print data (S307). In this case, the print job is temporarily stored in a storage unit such as the RAM 103 or the HDD 117, but printing based on the print job is executed without waiting for a print instruction to be input on the operation panel 110.

  When the function for forcibly holding the print job is enabled, the CPU 102 refers to the table shown in FIG. 4 (S304). FIG. 4 is a table showing whether or not to hold a print job of that type for each job type. A column 400 shows job types. A column 401 indicates whether to hold a print job. This table is stored in the RAM 103 or the HDD 117.

  The setting value in the column 401 is preferably set to ON for types of print jobs in which the number of print setting items that can be set by the external apparatus is small. This is because such a type of print job is reserved, so that the user can select print settings that cannot be selected by the external apparatus on the operation panel 110. However, the setting values in the column 401 may be changeable or may not be changeable. When the setting value in the column 401 can be changed, the user uses the operation panel 110 to change the setting value in the column 401.

  The CPU 102 determines whether or not to hold the print job based on the type of the print job determined in S302 and the table of FIG. 4 (S305). If it is determined that the print job is not retained, the CPU 102 proceeds to S307. If it is determined that the print job is to be retained, the print job is retained in a storage unit such as the RAM 103 or the HDD 117 (S306).

  FIG. 5 is a flowchart showing a print control process for executing reservation printing. The print control process is executed by the CPU 102 executing the control program.

  When the function key 204 is pressed, the CPU 102 causes the display unit 205 to display a list of one or more print jobs held in a storage unit such as the RAM 103 or the HDD 117 (S501). The user presses an arrow key 206 to select a desired print job from the list of print jobs, and presses an OK key 207. When the OK key 207 is pressed, the CPU 102 displays a print setting screen on the display unit 205 (S502).

  On the print setting screen, the user can change the print setting included in the print job or select a print setting that cannot be selected by the external apparatus. The user presses an arrow key 206 to select a desired print setting, and presses an OK key 207. After selecting a desired print setting, the user presses the start key 209 to input a print instruction. If the user does not need to change or select print settings, the user presses the start key 209 without pressing the arrow key 206 or the OK key 207.

  On the operation panel 110, six items such as Nin1, single-sided printing / double-sided printing, number of copies, monochrome printing / color printing, finishing (stapling, sorting, bookbinding, etc.), and the type of paper used for printing can be set.

  The CPU 102 determines whether a print instruction has been input (S503). When a print instruction is input, the CPU 102 controls the printing unit 106 to print the print data based on the print settings included in the print job and the print settings set on the operation panel 110 (S504).

  In the first embodiment, it is determined whether to hold a print job according to the type of print job. As a result, a print job that does not need to be retained can be executed promptly. On the other hand, a print job determined to be held can be executed after a print instruction is input on the operation panel 110.

<Second Embodiment>
In the first embodiment, it is determined whether to hold a print job based on the type of job. In the fourth embodiment, the print job setting value is also taken into consideration to determine whether to hold the print job. For example, when the number of pages of the print data is 1, print settings for assigning a plurality of pages to one sheet and print settings for specifying both sides are not necessary in the first place, and print setting items that can be set are reduced. For this reason, when the number of pages of print data is 1, it is less necessary to hold the print job. Therefore, in the second embodiment, it is determined whether to hold the print job in consideration of setting values such as the number of pages.

  FIG. 6 is a flowchart illustrating print control processing according to the second embodiment. The print control process is executed by the CPU 102 executing the control program. Since S301 to S307 in FIG. 6 are the same as S301 to 307 in FIG. 3, description of these steps is omitted.

  In step S601, the CPU 102 refers to the table shown in FIG. 7 and determines whether to hold the print job based on the print job setting value and the table shown in FIG. The job information of the print job includes setting values corresponding to each of a plurality of print setting items. The CPU 102 may determine the set value by analyzing the print data itself. For example, when the print setting value indicating the number of pages is not included in the job information, the number of pages can be determined by analyzing the print data.

  FIG. 7 is a table showing conditions for holding a print job for each print setting item. A column 700 indicates types of print setting items. A column 701 shows conditions for holding a print job (hereinafter, holding conditions). This table is stored in the RAM 103 or the HDD 117.

  In the example of FIG. 7, if the number of pages of print data is two or more, the print job is retained. If the layout of the print data is 1in1 (Nin1 indicates that N pages are allocated to one sheet), the print job is reserved. In the case of single-sided printing, the print job is reserved. If the number of copies is 1 or more, the print job is reserved. In the case of monochrome printing, the print job is reserved. In the present embodiment, it is determined that the print job is to be retained when the print job setting values satisfy all of the retention conditions 702 to 706.

  If it is determined in step S601 that the print job is not retained, the CPU 102 proceeds to step S307. If it is determined in step S601 that the print job is to be retained, the CPU 102 proceeds to step S306.

  The reservation condition can be changed by the user. 8 to 13 are examples of setting screens for setting reservation conditions. The setting screens shown in FIGS. 8 to 13 are displayed on the display unit 205.

  On the setting screen 801, the user can select a reservation condition to be changed. When the user presses the OK button 807, the CPU 102 stores the currently set retention conditions in the table of FIG.

  When the user presses a button 802, the CPU 102 controls the display unit 205 to display a setting screen 901 shown in FIG. When changing the reservation condition related to the number of pages, the user presses the numeric key 208 and inputs the number of pages in the input area 902. When the OK button 903 is pressed, the number of pages input in the input area 902 is set as a reservation condition, and a setting screen 801 is displayed on the display unit 205.

  When the user presses a button 803, the CPU 102 controls the display unit 205 to display a setting screen 1001 shown in FIG. The user presses one of the buttons 1002 to 1004 when changing the retention condition related to the layout. When an OK button 1005 is pressed, the selected layout is set as a reservation condition, and a setting screen 801 is displayed on the display unit 205.

  When the user presses a button 804, the CPU 102 controls the display unit 205 to display a setting screen 1101 shown in FIG. The user presses one of the buttons 1102 and 1103 when changing the reservation condition related to single-sided printing / double-sided printing. When the OK button 1104 is pressed, the selected single-sided printing or double-sided printing is set as a holding condition, and a setting screen 801 is displayed on the display unit 205.

  When the user presses a button 805, the CPU 102 controls the display unit 205 to display a setting screen 1201 shown in FIG. The user presses the numeric key 208 and inputs the number of copies in the input area 1202 when changing the reservation condition related to the number of copies. When the OK button 1203 is pressed, the number of copies input in the input area 1202 is set as a reserve condition, and a setting screen 801 is displayed on the display unit 205.

  When the user presses a button 806, the CPU 102 controls the display unit 205 to display a setting screen 1301 shown in FIG. The user presses one of the buttons 1302 and 1303 when changing the reservation condition related to monochrome printing / color printing. When an OK button 1304 is pressed, the selected monochrome printing or color printing is set as a holding condition, and a setting screen 801 is displayed on the display unit 205.

  In the second embodiment, whether or not to hold a print job is determined based on the type of print job and the set value of the print job. A print job that is unlikely to be changed in print settings and has a low necessity to retain can be executed promptly. On the other hand, a print job determined to be retained in consideration of the print settings can be retained.

  In the second embodiment, setting values indicating the number of pages, layout, single-sided printing / double-sided printing, number of copies, monochrome printing / color printing are used, but setting values of other print setting items may be used. .

<Third Embodiment>
In the first and second embodiments, the MFP 100 determines whether to hold a print job based on the type of job. In the third embodiment, MFP 100 determines whether to hold a print job based on the type of protocol for transferring the print job.

  FIG. 14 is a flowchart illustrating print control processing according to the third embodiment. The print control process is executed by the CPU 102 executing the control program. Since S301, S303, S306, and S307 in FIG. 14 are the same as S301, S303, S306, and S307 in FIG. 3, description of these steps is omitted.

  In step S1401, the CPU 102 determines the protocol used to transfer the print job. In this embodiment, the protocol used to transfer the print job is LPR, RAW, WSD, or IPP. LPR is an abbreviation for Line PRinter daemon protocol. WSD is an abbreviation for Web Services for Devices. IPP is an abbreviation for Internet Printing Protocol.

  When the network interface 113 receives a packet including a print job from the external device via the network, the CPU 102 receives the packet via the network interface 113. The CPU 102 analyzes the packet and determines a protocol corresponding to the packet. For example, when a different port number is assigned to each of four types of protocols, the print job protocol is determined based on the port number included in the packet. The print job protocol may be determined based on the packet structure and the identifier included in the packet.

  In S1402, the CPU 102 refers to the table shown in FIG. FIG. 15 is a table showing, for each protocol type, whether or not to hold a print job transferred with that type of protocol. A column 1500 indicates a protocol type. A column 1501 indicates whether to hold a print job. This table is stored in the RAM 103 or the HDD 117.

  Which protocol is used depends on the printing system. In this embodiment, it is assumed that LPR and RAM are used for PC printing, and WSD and IPP are used for cloud printing.

  The setting value in the column 1501 is preferably set to ON for a protocol used in a printing system in which the number of print setting items that can be set by an external apparatus is small. This is because the print job transferred by such a type of protocol is reserved, so that the user can select a print setting that cannot be selected by the external apparatus on the operation panel 110. However, the setting values in the column 1501 may be changeable or may not be changeable. When the setting value in the column 1501 can be changed, the user changes the setting value in the column 1501 using the operation panel 110.

  In FIG. 15, there are four types of protocols, but other protocols may be used. For example, it is possible to determine whether WiFi is used to transfer a print job, and to hold the print job if WiFi is used.

  In step S1403, the CPU 102 determines whether to hold the print job based on the protocol determined in step S1401 and the table shown in FIG. If it is determined that the print job is not retained, the CPU 102 proceeds to S307. If it is determined that the print job is to be retained, the CPU 102 proceeds to S306.

  In the third embodiment, it is determined whether to hold a print job according to the protocol used to transfer the print job. As a result, a print job that does not need to be retained can be executed promptly. On the other hand, a print job determined to be held can be executed after a print instruction is input on the operation panel 110.

<Fourth Embodiment>
In some cases, the retention of a print job can be specified by an external device. When the user designates hold of a print job with an external device, the print job includes a print setting for instructing hold of the print job.

  In the fourth embodiment, even when the function for forcibly holding a print job is not effective, if the print setting for instructing the print job is included in the print job, the MFP 100 holds the print job. .

  FIG. 16 is a flowchart illustrating print control processing according to the fourth embodiment. The print control process is executed by the CPU 102 executing the control program. Since S301 to S307 in FIG. 16 are the same as S301 to S307 in FIG. 3, description of these steps is omitted.

  In step S <b> 1601, the CPU 102 determines whether the print job includes a print setting that instructs to hold the print job. If such print settings are included in the print job, the CPU 102 proceeds to S306.

  In the fourth embodiment, even when the function for forcibly holding a print job is not effective, if the user who issued the print job wants the print job to be held, the print job is Can be retained. On the other hand, even if the user cannot select the print setting that indicates that the print job is to be retained, the user can use the function to retain the print job by enabling the function to forcibly retain the print job. can do.

  Although FIG. 16 shows the modification of FIG. 3, FIGS. 6 and 14 may be modified similarly to FIG. That is, S1601 in FIG. 16 may be added to the flowcharts in FIGS.

<Fifth Embodiment>
In the first to fourth embodiments, it is determined whether or not to hold a print job based on the job type and protocol. In the fifth embodiment, based on the job type and protocol, it is determined whether to hold the print job so that the print setting can be changed / added or whether to hold the print job without changing the print setting. That is, in the fifth embodiment, the CPU 102 keeps the print job in a storage unit such as the RAM 103 or the HDD 117 in S307 of FIGS. However, even if the print job reserved in S307 is selected in S501, the CPU 102 does not display the print setting screen on the display unit 205, but causes the printing unit 106 to print the print data in accordance with pressing of the start key 209. Control.
