Abstract

PROBLEM TO BE SOLVED: To provide a display method of print setting for displaying correct information on a print system UI even if a printer search and acquisition of option information of a printer are not performed simultaneously in a mobile print system.SOLUTION: Print plug-ins 214, 215 transmit capacity information of a printer to a print system 210 by searching for a printer 120 existing on a network 100. When option capacity of a printer must be transmitted from the print plug-ins to the print system, acquisition of the option capacity is not performed, and a default value or a tentative value of the option capacity is transmitted to the print system. When a user starts printing or shifts to an expansion setting screen, the user communicates with a printer to acquire the option capacity of the printer, and transmits a correct value to the print system by using the acquired data when transmitting printer capacity information in the next printer search.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a display method for print settings when performing printing.

  Conventionally, there is a technique for transmitting print data to a printer in a mobile OS. In some cases, a mobile OS incorporates a printing framework called a printing system, and a printing vendor can realize a printing function.

  For example, in an OS installed in a mobile terminal such as Android (Android is a registered trademark of Google Inc.), there is a “printing system” that provides a printing function common to each application (installed in Android Version 4.4 or later). In addition, the printing system has a mechanism that allows each printer vendor called “print plug-in” to add in a plug-in format for dependent processing for adapting to their print processing apparatus. For example, Canon Print Service (Canon Print Service is a registered trademark of Canon Inc.) is provided as Android's “print plug-in”, and downloaded from Google Play (Google Play is a registered trademark of Google Inc.) and installed. can do.

  By using the printing system, the user can perform printer search, printing, and status acquisition processing from the UI of the printing system. When acquiring the printer status, the printer function information can be reflected in the print setting UI of the printing system by sending the printer capability information from the printing plug-in to the printing system. For example, it is possible to display all the paper sizes supported by the printer, and to switch between enabling / disabling of the duplex function.

  The acquisition of the printer capability is general-purpose for the basic information that can be found in any printer, such as the printer name and color / monochrome. It is common to make an inquiry to the printer after finishing. However, for optional functions that are not provided in all printers, information is often acquired at a timing other than the above in order not to spend time in searching for printers.

There are several ways to acquire optional capabilities, but apart from the printer search process, a method in which the printer and mobile terminal communicate directly to acquire optional information supported by the printer is a method for mobile printing applications. It is common. This method has the advantage that resources can be reduced because the printing application does not have a static file, and the maintenance work of the application can be reduced. Other printer capability information acquisition methods include a method for managing printer information using a static file and a method for acquiring printer information from a server.
The mobile terminal can acquire the above-mentioned optional capabilities at the same time when searching for a printer, and can also acquire the optional capabilities at an arbitrary timing, not when searching for a printer.

  When acquiring information on a printer from a terminal, it is discomforting to the user by displaying that capability information is being acquired until the printer information can be acquired. Not to give.

JP 2008-310420 A

  On the other hand, when communicating from the print plug-in to the printer to acquire the optional capabilities of the printer, there are a lot of information on the network signal conditions, optional capabilities acquired from the printer, and other environmental factors. Therefore, communication between the terminal and the printer often takes time. Therefore, if the printer search process and the option capability acquisition process are performed simultaneously, it takes time to reflect the print setting UI on the printing system.

  In order to update the print setting UI without taking time, the print plug-in should not simultaneously acquire the option information when acquiring the capability information of the printer.

  However, if the printer search and the option information of the printer are not acquired at the same time, the information displayed on the UI of the printing system may not be satisfied, and there is a problem that correct information cannot be displayed on the UI.

  In the present specification, a problem that correct printer information may not be displayed on the print system UI when the correct printer information is immediately displayed on the print system UI is considered.

The program according to the present invention is:
When the optional capability of the printer is transmitted from the printing plug-in to the printing system, the default capability or the temporary value is transmitted for the optional capability without acquiring the optional capability. When the user starts printing or shifts to the advanced setting screen, the printer acquires the optional capabilities of the printer by communicating with the printer, and uses the acquired data for sending the printer capability information at the next printer search. Then, information on the correct option capability of the printer is transmitted to the printing system.

  According to the program of the present invention, when the printing system makes an inquiry about the printer capability to the printing plug-in, the information can be returned to the printing system and the UI can be updated with little time. When the user acquires the correct optional function information when the user enters the advanced settings screen or starts printing, the next time the printer system queries the printer capabilities, the printing plug-in The correct capability information is returned and the UI can be updated.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  First, the overall configuration of the system in this embodiment will be described.

  FIG. 1 shows an example of the overall configuration of the system in this embodiment. In this system, a network 100, an information processing terminal 110, and a printer A120 are connected to each other. At this time, a plurality of information processing terminals and printers may be provided on the network.

  The network 100 is a standard network connection and may be in the form of either the Internet or an intranet. The connection method may be a method of forming a network via a Wi-Fi router or a Wi-Fi direct information processing terminal 110. And the printer A 120 may be directly connected, and any connection form may be used as long as the information processing terminal 110 and the printer A 120 are connected to each other via a network.

  Next, the configuration of the information processing terminal 110 and the printer A 120 in the embodiment of the present invention will be described with reference to FIG.

  The information processing terminal 110 is a normal mobile terminal (PDA or smart phone), and an operating system for a small terminal and a program for controlling a call and data communication are running. Further, the information processing terminal 110 can use wireless communication using the network controller 114. Each component of the hardware is connected to the system bus 119. The ROM 112 is a non-volatile storage device, an OS for controlling the information processing terminal 110, an application for controlling telephone calls and data communication, various operation mode settings that need to be retained after the information processing terminal 110 is restarted, Operation logs are stored. Mail software, a Web browser, etc. are mentioned as an application which controls the data communication stored in ROM112. Information stored in the ROM 112 is processed by the CPU 111. In addition, the CPU 111 executes processing based on a program stored in the ROM 112, thereby realizing the software configuration of the information processing terminal 110 as shown in FIG.

  The RAM 113 is a work memory area for executing a program. It is also a memory for temporarily storing image information generated by an application during printing.

  The network controller 114 is a chip for controlling network communication, and Wi-Fi, Wi-Fi direct, and public line 3G / 4G are used for communication.

  The display control unit 115 controls information output on the display 117 of the information processing terminal 110. The input control unit 116 controls information instructed by the user through the input unit 118 such as a button or a touch panel of the information processing terminal 110. Using these display control unit 115 and input control unit 116, the application on the information processing terminal 110 provides the network communication information and various information on the information processing terminal 110 to the user.

  In the printer A 120, reference numeral 121 denotes a network I / F, which is used for connection to the information processing terminal 110 via the network 100. A CPU 122 outputs an image signal as output information to the printer engine 125 connected to the system bus 126 based on a control program. The control program is stored in the ROM 124. The printer A 120 can communicate with the information processing terminal 110 via the network I / F 121, and is configured to be able to notify the information processing terminal 110 of information in the printer A 120. Further, the CPU 122 executes processing based on an application program stored in the ROM 124. Reference numeral 123 denotes a RAM which functions as a main memory, work area, and the like for the CPU 122. The RAM 123 is used as an output information expansion area, environment data storage area, NVRAM, and the like. The ROM 124 stores a control program for the CPU 122, font data used when generating the output information, information used on the printer 120, and the like. A printer engine 125 outputs an image signal as output information. A system bus 126 connects each device.

  FIG. 3 is a block diagram illustrating the software configuration of the present embodiment.

  First, the software configuration of the information processing terminal 110 is shown. Each module configuring the information processing terminal 110 is a program module that exists as a file stored in the ROM 112. Then, it is loaded into the RAM 113 and executed by the OS and modules that use the module at the time of execution. The processing described in the present embodiment is realized by reading the application stored in the ROM 112 and the program of each module (software) into the RAM 113 as necessary and executing it by the CPU 111.

  A printing system 210 provides a common printing interface for each application such as App A211. An application can use a printing function by implementing an interface defined in the printing system. At this time, the printing system instructs a printing plug-in such as Plugin D213 to print or search.

  App A 211, App B 212, and App C 213 are general applications that operate on the OS of the information processing terminal 110, and include applications such as a Web browser, a PDF viewer, an Office viewer, a photo application, and a mail application. These apps implement a printing interface defined by the printing system.

  Plugin D214, Plugin E215, and print plug-in 216 are print plug-ins that cannot be used by the user as stand-alone applications, and exist as services for providing functions to the print system. The functions provided by the Plugin D214 to the printing system 210 include a printer search function on the network, a printing function, a print setting function, a status notification function, and the like. There may be a plurality of printing plug-ins such as Plugin D214 as shown in FIG.

  A print plug-in 216 is a print plug-in that performs this embodiment. The basic configuration is the same as Plugin D214 and other printing plug-ins. The print job generation module 217 receives a command from the printing system 210 and generates a print job that can be printed by the printer A 120 from information in the ROM 112 and the RAM 113.

  The UI display module 218 displays a setting screen unique to the print plug-in 216. The printing system 210 may have an interface for displaying an extended setting screen on a printing plug-in for each vendor, and can perform more settings than the basic settings that can be set by the printing system 210.

  The communication supervision module 219 is a module that controls communication between the print plug-in 216 and the printer A 120, and manages printer capability acquisition, status acquisition, printer search, and print job transmission.

  The network module 220 is a module for connecting the print plug-in 216 and a printer such as the printer A 120, and provides a function of communicating with an external device using a protocol such as HTTP or SNMP.

  Next, the software configuration of the printer A 120 will be described.

  The network module 200 is a module that performs communication between the printer A 120 and the information processing terminal 110, and provides a function of communicating with an external device using a protocol such as HTTP or SNMP.

  The print processing module 201 is a module for creating image data and sending drawing data to the printer engine 125 in order to execute printing.

  Next, a procedure for starting the printing system 210 will be described. FIG. 4 shows an example of a UI when an application such as App A211 uses a printing function using a printing system. When the user presses the menu button 400, the menu opens. By pressing the button 401, the OS printing system screen as shown in FIG.

  FIG. 5 is an example of a print setting UI of a printing system provided by the OS. Reference numeral 500 in FIG. 5 denotes a printer searched by the print plug-in 216 on the network. When a plurality of printers are available, the printers can be switched. Reference numeral 501 denotes a button for changing print settings, which can change print settings for standard functions. Reference numeral 502 denotes a button for displaying extended settings. When the print plug-in 216 has an extended function setting interface, an extended setting screen as shown in FIG. 6 can be displayed. Reference numeral 503 denotes a print button. When tapped, a print command is sent from the print system 210 to the print plug-in 216.

  FIG. 6 is an example of an extended setting screen of the print plug-in, and items that cannot be set in the print dialog in FIG. 5 can be set by a printing vendor's original implementation.

  FIG. 7 shows an example of a data format when the print plug-in acquires printer option information through network communication with the printer. The configuration of the option information 701 includes information such as a model name 702 indicating the model name of the printer, a stapling position 703 indicating the stapling position supported by the printer, and the presence / absence of a duplex unit 704 indicating whether the printer is equipped with a duplex unit. Each piece of information is composed of a character string and an array of numbers as shown at 705.

  FIG. 8 shows a flowchart of transmission of information relating to the capabilities of the printer from the print plug-in 216 to the printing system 210, which is executed from the application on the information processing terminal 110.

  In step S801, in the network 100 in which the printer A 120 and the information processing terminal 110 participate, the information processing terminal 110 broadcasts SNMP to the network in order to search for a printer managed by SNMP. Further, in step S802, within a few seconds after performing step S801 (for example, 1 second), the printer capable of printing by the print plug-in 216 is determined from the network devices that have responded to the broadcast SNMP. Then, the result is reflected on the print setting screen as shown in FIG.

  In step S803, the print plug-in 216 inquires the printer searched in step S802 for basic information about the printer using SNMP communication in the same manner as described above. The information inquired here is only general information such as color / monochrome.

  In step S804, the printer capability information to be transmitted to the printing system 210 is compared with the basic information acquired in step S803, and it is determined whether there is enough information to be transmitted to the printing system 210. If there is not enough information to be sent to the printing system 210 by the printing plug-in 216, a temporary value such as a default value is sent for the missing information to be sent to the printing system 210 in step S805. . If it is determined in step S804 that all the printer capability information to be transmitted to the printing system 210 is sufficient, the print plug-in 216 transmits the correct printer capability information to the printing system 210 and ends the processing. By this processing, the UI of the printing system as shown in FIG. 5 is updated without taking time, and the user can immediately change the print setting.

  Step S901 shows a case where the user presses the button 502 from the print setting screen of the printing system 210 shown in FIG. When the user presses a button 502, the information processing terminal 110 transitions to an extended setting screen shown in FIG. A different function is installed for each vendor on the extended setting screen UI unique to the print plug-in, and the print plug-in 216 can add a unique function on this screen.

  In step S <b> 902, it is determined whether printer configuration information is stored in the print plug-in 216. The configuration information is capability information such as which option a printer such as 701 in FIG. 7 supports, and is in the form of a character string and a number array as shown in 705 in FIG.

  Through the process of acquiring configuration information, it is possible to acquire information regarding optional functions supported by the printer, such as what options and finishers the printer is equipped with. Since the configuration information is associated with the MAC address of the printer and stored in the print plug-in 216, one configuration information is associated with one printer and stored. If the configuration information is stored in the printer A 120, the extended setting screen is configured using the configuration information that has already been acquired, as shown in S903.

  If the printer configuration information is not stored in step S902, a configuration information acquisition process is performed in step S904. The configuration information acquisition process is performed by directly communicating with the printer using an information acquisition protocol. This configuration information acquisition process may take time depending on the communication status and the amount of data to be acquired.

  In step S905, the acquired configuration information is stored in the application in association with the MAC address of the printer. The area to be saved is saved in the non-volatile ROM 112 so that even when the information processing terminal 110 is restarted, it is not necessary to reacquire information.

  In step S906, an extended setting screen as shown by 600 in FIG. 6 is generated according to the configuration information acquired in step S905.

  When the user presses the print button 503 shown in FIG. 5, the processing of the flowchart shown in FIG. 10 is performed. In step S <b> 1001, the printing system 210 issues a print command to the print plug-in 216.

  In step S1002, the print plug-in 216 determines whether the configuration information of the printer associated with the printer to be printed has already been acquired. If the configuration information of the printer to be printed has been acquired, printing processing is performed in step S1003. The printing process is a process in which the print plug-in 216 receives data from the printing system 210, converts the received print data into image data by the print job generation module 217, and transmits the image data to the printer A 120. .

  If it is determined in step S1002 that the configuration information corresponding to the printer to be printed has not been acquired, the process proceeds to step S1004 to acquire printer configuration information. The printer configuration information acquisition processing method is the same as that in step S1002.

  In step S1005, the printer configuration information acquired in step S1004 is compared with the print settings instructed from the printing system 210 to the print plug-in 216, and it is determined whether a prohibition has occurred. If no prohibition has occurred in the print settings and the printer configuration information acquired in step S1004, the process proceeds to step S1006 to execute printing. The contents of the printing process are as described above. If a prohibition has occurred in step S1005, the process proceeds to step S1007 to notify the user whether to continue the printing process. For example, in the case of Android OS, there is a method of allowing the user to select whether or not to continue the printing process using the notification bar using an API that issues Notification to the notification bar. If the user continues printing in step S1008, the print job is transmitted to the printer A 120 with the currently set information. If the user does not continue the printing process in step S908, the printing process is interrupted in step S1010, and the printing is terminated.

  Through the above processing, when the printer capability information is requested from the printing system and the information is immediately returned, the default value or the temporary value is returned, so that the printing system UI can be updated immediately. In addition, when a transition to the print or extended setting screen is performed, the correct capability information can be returned when the printer system requests the capability information of the printer next time.

  The processing described in the present embodiment is realized by reading the application stored in the ROM 112 and the program of each module (software) into the RAM 113 as necessary and executing it by the CPU 111.

  In step S804 of the first embodiment, if the user has never performed the process of printing and shifting to the extended setting screen, the configuration information is not acquired. If there is a lack of information, a temporary value must be set. The print plug-in should display the correct value as much as possible on the print setting screen shown in FIG.

  Therefore, when the configuration information has not yet been acquired, if the user opens the print setting screen, the printer configuration information is acquired, and if no response is returned within a certain threshold time, the first embodiment If the response is returned, the correct setting is returned to the printing system.

  In step S1101, in the network 100 in which the printer A 120 and the information processing terminal 110 participate, processing similar to that in step S801 is performed, and a search is started.

  In step S1102, the same processing as in step S802 is performed, and a printable printer existing on the same network of the information processing terminal is searched by SNMP communication.

In step S1103, the printer basic information is acquired as in step S803.
The determination in step S1104 is the same as the determination in step S804. The information requested from the printing system is compared with the information acquired in step S1103 to determine whether the information to be sent to the printing system 210 is sufficient. If the information is sufficient, the process proceeds to step S1105, and correct printer capability information is transmitted to the printing system.

  In step S1106, it is determined whether the printer configuration information found in step S1102 is already stored in the information processing terminal 110. When the printer configuration information is already stored in the information processing terminal 110, the process proceeds to step S1105, and the correct printer capability information is transmitted to the printing system 210 according to the stored capability information.

  If the printer configuration information is not saved in step S1106, acquisition of configuration information is started in step S1107 in the same procedure as in step S904 in order to acquire more detailed printer capability information.

  In step S1108, it is determined whether or not there is a response from the printer within a certain time with respect to the configuration information acquisition process started in step S1107. For example, if the threshold is set to 0.5 seconds, it is determined whether the printer configuration information has been acquired within 0.5 seconds.

  If the configuration information acquisition process is completed within a predetermined time in step S1108, the process proceeds to step S1105, and correct option information is transmitted to the printing system based on the printer configuration information acquired in step S1107.

  If it is determined in step S1107 that the configuration information cannot be acquired within a certain period of time, in step S1109, the information to be transmitted to the printing system determined in step S1104 is obtained by acquiring the configuration information. Those that could not be acquired are transmitted to the printing system 210 as default values or provisional values.

  Further, the process at the time of shifting to the extended setting screen and at the start of printing is performed in the same manner as in FIG. 9 and FIG.

  With the above processing, if the configuration information acquisition processing has not been performed yet, the printer configuration information acquisition processing is attempted when the printer capability information is requested from the printing system, and there is a response from the printer within a predetermined time. If so, the correct capability information can be returned to the printing system.

  The processing described in the present embodiment is realized by reading the application stored in the ROM 112 and the program of each module (software) into the RAM 113 as necessary and executing it by the CPU 111.

  In the first embodiment, the same setting may be held on the print setting screen of the printing system illustrated in FIG. 5 and the extended setting screen illustrated in FIG. 6. By displaying the same setting value on both setting screens, May be confusing to users. Therefore, in the third embodiment, the print setting shown in FIG. 5 is compared with the extended setting shown in FIG. 6, and if there is the same setting item, a process of hiding that item from the extended setting screen of FIG. 6 is added.

  In step S1201, the extension setting screen in FIG. 6 is opened by pressing 502 in FIG. In step S <b> 1202, information indicating what has been input to which item on the print setting screen illustrated in FIG. 5 is acquired from the print system 210 from the print system 210. For example, before moving to the extended setting screen, information on what is set in the number of copies, paper size, color, stapling, double-sided, and printing range is acquired by an application-related function (using Intent etc. in Android OS) .

  In step S1203, at the time of transition to the extended setting screen in FIG. 6, the extended setting information supported by the printer selected in FIG. 5 is acquired by performing saved configuration information or configuration information acquisition processing.

  In step S1204, the setting of the printing system acquired in step S1202 is compared with the corresponding function of the printer acquired in step S1203. If the same setting is made in step S1204, for example, if there is a duplex function on the setting screen provided by the printing system in FIG. 5 and the duplex function can also be set on the extended setting screen in FIG. 6, the process proceeds to step S1205.

  In step S1205, if there is an item that can be set on the print setting screen of FIG. 5 and the same candidate on the extended setting screen of FIG. 6, the item is not displayed from the extended setting screen of FIG. Only the difference from the print setting screen is displayed.

  In step S1206, if there is no same setting item in the print setting screen of FIG. 5 and the extension setting screen of FIG. 6 in step S1204, all functions supported by the printer are displayed on the extension setting screen.

  In this embodiment, the printer search process and the print process are the same as those in FIGS. 8 and 10 of the first embodiment.

  With the above processing, when there are the same setting items on the print setting screen of the printing system and the extended setting screen, the items can be hidden from the extended setting screen to avoid confusion for the user.

  The processing described in the present embodiment is realized by reading the application stored in the ROM 112 and the program of each module (software) into the RAM 113 as necessary and executing it by the CPU 111.

  In the first embodiment, the same setting may be held on the print setting screen of the printing system illustrated in FIG. 5 and the extended setting screen illustrated in FIG. 6. By displaying the same setting value on both setting screens, There is a challenge that can be confusing to users. Therefore, in the fourth embodiment, the print setting shown in FIG. 5 is compared with the extended setting shown in FIG. 6, and if there is the same setting item, a change in one screen is reflected on the other screen. Add.

In step S1301, the extension setting screen in FIG. 6 is opened by pressing 502 in FIG.
In step S1302, the item currently set in the print setting is acquired by the same method as in step S1202.

  In step S1303, processing similar to that in step S1203 is performed to acquire information on functions supported by the printer.

  In step S1304, processing similar to that in step S1204 is performed, and the setting items of the printing system are compared with the settings supported by the printer. If it is determined in step S1304 that the setting items in the printing system in FIG. 5 and the setting items in the extended setting in FIG. 6 are the same, the process proceeds to step S1305. In step S1306, all the corresponding functions of the printer are displayed on the extended setting screen in FIG. 6, and those having the same setting items compared in step S1304 are set in the printing system UI in FIG. The setting contents are also reflected on the extended setting screen of FIG. For example, if the “double-sided” function is set to ON in FIG. 5, the “double-sided” function ON is also displayed on the extended setting screen of FIG.

  If the same setting is not found in step S1304, all the corresponding functions of the printer are displayed in step S1306 at the transition of the extended setting screen in FIG.

  Step S1401 is that the user performs an operation of closing the extension setting screen on the extension setting screen of FIG. For example, pressing the back key of the terminal can be considered.

  In step S1402, the value finally set by the user on the extended setting screen of FIG. 6 is acquired.

  In step S1403, a list of items that can be set in the print dialog in FIG. 5 is acquired. For items that can be set, the table of values set in the print setting UI of the printing system acquired in step S1302 is used.

  In step S1404, the setting items acquired in step S1402 and step S1403 are compared to determine whether there is the same setting. If the same setting is made in step S1404, the process proceeds to step S1405, and the value set in the extended setting screen in FIG. 6 is set for the print setting in the print setting screen in FIG. For example, when the “double-sided” function is set to ON in the extended setting screen of FIG. 6 and the print setting screen of FIG. 5 is displayed, and the print setting screen of FIG. Is sent to the printing system, and the “both sides” function ON is displayed on the print setting screen of FIG. If the same setting is not found in step S1404, the value acquired from the print dialog is returned to the printing system as it is without being changed in step S1406.

  In this embodiment, the printer search process and the print process are the same as those in FIGS. 8 and 10 of the first embodiment.

  Through the above processing, when there are the same setting items on the print setting screen of the printing system and the extended setting screen, it is possible to prevent the user from being confused by reflecting the change of both screens on both sides.
