Each part is connected to SoC 2001, and the mobile terminal 2000 can be connected to the network via the access point 2013. In the present embodiment, the OS (operating system) is assumed to be, for example, Google's Android OS (registered trademark), but is not limited thereto.

A software configuration that operates on the mobile terminal 2000 will be described with reference to FIG. The program of this software is stored in the flash memory 2003. Applications 112 to 114 are installed in the mobile terminal 2000 and have a display function and a printing function of contents such as a photo, a document, and a Web page via a printing system 100. The print system 100 is a part of the framework of the operating system, and is composed of a UI (User Interface) unit 101, a print plug-in control unit 102, a communication unit 103, a print plug-in management unit 104, and a detection result receiving unit 105. .. The UI unit 101 provides a user interface for the printing system 100. The print plug-in control unit 102 controls the operation of the print plug-in (print plug-in) installed in the mobile terminal 2000. The print plug-in is installed in the mobile terminal 2000, and adds a search function for searching at least a printer to the OS running on the mobile terminal 2000. The communication unit 103 uses WiFi to perform network communication with the printer. The print plug-in management unit 104 manages information on the print plug-in installed in the mobile terminal 2000. The detection result receiving unit 105 receives a notification of the detection result when the print plug-in detects a printer on the network.

The print plug-ins 200, 210, and 220 have functions such as searching for a printer, generating a print job, and acquiring a printer status, and act as a bridge between the printing system 100 and the target printer. Each plug-in can be installed and uninstalled as needed, and the print plug-in management unit 104 manages the installation state of each plug-in.

Since all the print plug-ins have the same configuration, the print plug-in 200 will be described below. The printer search unit 201 searches for a printer on the network by using multicast or broadcast. As a protocol, SLP (Service Location Protocol), Multicast-DNS (Domain Name System), or the like is used. However, the protocol is not limited to this, and the protocol may be different for each plug-in. The print processing unit 202 performs rendering processing on PDL (Page Description Language) data or image data that can be printed by the printer 1001. The package name 203 is a unique name assigned to the print plug-in 200, and is, for example, "jp.co.aaa.xxxxxx". A different package name is assigned and retained for each print plug-in.

FIG. 4 shows an example of a display screen of an application that implements the functions of the printing system 100. When the user taps the print button 401 on the application screen 400 on which the content to be printed is displayed, the UI unit 101 of the print system 100 is called and the print setting screen 402 is displayed. The print setting screen 402 includes a target printer display area 403, a print setting area 404, and a print button 405. After the user confirms the desired print setting in the print setting area 404, by tapping the print button 405, the content data of the application is output to the printer displayed in the target printer display area 403. FIG. 4 shows an example in which the printer “Printer-A” having the IP address “192.168.0.10” is selected. When the output destination is changed to another printer, the user taps the target printer display area 403 to display the printer list screen described later. On the printer list screen, the model name of the printer is displayed as a selection candidate together with the package name of the print plug-in and presented to the user.

In this embodiment, the invalid print plug-in is enabled by displaying the link button for displaying the plug-in setting screen that can set the installed print plug-in to the enabled state or the disabled state on the printer list screen. The method of doing this will be described.

By tapping the target printer display area 403 on the print setting screen 402 shown in FIG. 4B, the user can instruct the search for a printer. FIG. 6 is a flowchart showing an example of the operation of the printing system 100 after the search for the printer is instructed.

The process described in this embodiment is realized by loading the program recorded in the flash memory 2003 into the RAM 2002 and executing the program in the SoC 2001.

First, the target printer display area 403 is tapped on the print setting screen 402 (S601). Then, the print plug-in control unit 102 acquires a list of print plug-ins installed in the mobile terminal 2000 via the print plug-in management unit 104 (S602).

Next, the printer search unit of the print plug-in set to the enabled state among all the print plug-ins in which the print plug-in control unit 102 is installed is called (S603). In the step of S603, the printer search unit of each of the active print plug-ins searches for the corresponding printer connected to the same network by a predetermined protocol according to the instruction from the printing system 100. The printer search unit of each print plug-in notifies the detection result receiving unit 105 of the printing system 100 of the searched result.

In the step of S604, the print plug-in control unit 102 acquires the enabled / disabled state of each plug-in installed via the print plug-in management unit 104. The print plug-in control unit 102 determines the valid / invalid state acquired in the step of S604, and determines whether or not there is a print plug-in in the invalid state (S605).

If it is determined in the step of S605 that the print plug-in in the invalid state does not exist, the process proceeds to the step of S606, and the detection result receiving unit 105 enters the reception standby state of the detection result notification from the print plug-in. Next, in the step of S607, it is determined whether or not the detection result receiving unit 105 has reached the timeout. If it is determined that the time-out has not been reached, the detection result receiving unit 105 determines whether or not the detection result notification has been received from the print plug-in in the step of S608. In the step of S608, when the detection result receiving unit 105 receives the result notified from the printer search unit of the print plug-in, it is determined that the detection result has been received. When the detection result receiving unit 105 receives the notification of the detection result, the process proceeds to step S609, and the UI unit 101 updates the printer list screen 500 as shown in FIG. 5A, displays the printer detection result, and displays the printer detection result. Proceed to the step of S606. When a printer is detected, the printer information as shown in 501 to 503 of FIG. 5A and the print plug-in that detected the printer are added to the printer list and displayed. If the detection result receiving unit 105 does not receive the detection result notification in S608, the process returns to the step of S606.

On the other hand, if it is determined in the step S605 that the print plug-in in the invalid state exists, the process proceeds to the step S610. In the step of S610, the UI unit 101 adds the link button 504 to the plug-in setting screen 510 to the printer list screen 500 of FIG. 5A, and then proceeds to the step of S606.

After continuing the processing of S606 to S609 until it is determined that the time-out has been reached in the step of S607, the printer list screen display processing is terminated.

When the user taps the area of the link button 504 to the plug-in setting screen, the screen transitions to the plug-in setting screen 510 as shown in FIG. 5 (b), and the UI unit 101 is already installed. Display a list of plugins. The plug-in setting screen 510 is provided by a setting application installed as standard in the operating system. Specifically, the plug-in setting screen 510 is a screen that can be accessed by starting the setting application. Here, "ON" is displayed when the print plug-in is enabled, and "OFF" is displayed when the print plug-in is disabled, together with the plug-in name. When the area of the disabled BBB print service 511 among a plurality of print plug-ins (print service in the figure) is tapped, the setting screen 520 for switching the enabled / disabled state of the print plug-in as shown in FIG. 5 (c) is displayed. Transition. By operating the button 521 on this setting screen, it is possible to change the disabled BBB print service to the enabled state, and when the setting is changed, the print plug-in management unit 104 updates to the flash memory 2003. Stores the settings of. In this way, the operating system manages whether the plurality of print plug-ins are in the enabled state or the disabled state by the plug-in setting screen 510.

As a result, the disabled BBB print service 511 can be easily changed to the enabled state, and the printer can be searched and the detection result can be displayed using the BBB print service 511.

In this embodiment, an example of changing the disabled print plug-in to the enabled state on the printer list screen without transitioning to the plug-in setting screen will be described.

FIG. 8 is a flowchart showing an example of the operation of the printing system 100 after the target printer display area 403 is tapped on the print setting screen 402 shown in FIG. 4B. For the same processing as the step already described, the same number as the step number already described is assigned, and the description is omitted unless otherwise specified.

The process described in this embodiment is realized by loading the program recorded in the flash memory 2003 into the RAM 2002 and executing the program in the SoC 2001.

If it is determined in the step of S605 that the print plug-in in the invalid state exists, the process proceeds to the step of S810. In the step of S810, the UI unit 101 adds a print plug-in activation button associated with the print plug-in determined to be in the invalid state in the step of S605 to the printer list screen. In this embodiment, it is assumed that the print plug-in 210 is in an invalid state. Then, it is assumed that the print plug-in activation button 701 is associated with the print plug-in 210. In such a case, in S810, the print plug-in activation button 701 is added to the printer list screen 700 as shown in FIG. 7A.

FIG. 8B shows the processing of the printing system 100 when the print plug-in activation button 701 is tapped.

When the print plug-in activation button 701 is tapped, the print system 100 activates the print plug-in 210 associated with the print plug-in activation button via the print plug-in management unit 104 (S851). As described above, the printer list screen of this embodiment informs the user that the print plug-in in the disabled state exists, and also has a function as a setting screen for changing the enabled / disabled state of the print plug-in.

Next, in the step of S852, the print plug-in control unit 102 calls the printer search unit 211 of the print plug-in 210. As a result, it is determined that the print plug-in 210 changed to the valid state detects the printer corresponding to the printer-D, and that the detection result is received in S608 of FIG. 8A. As a result, the detection result of the print plug-in 210 is added to the originally displayed detection result. In the example of FIG. 7 (b), Printer-D is added in addition to the detection result of FIG. 7 (a).

In this embodiment, when an instruction to display the print setting screen is given, if an invalid print plug-in exists, it notifies that there is an invalid print plug-in and prints in the invalid state. This section describes how to display a warning screen that can change the plug-in to the enabled state.

The process for displaying the list of printers on the network on the screen will be described.

FIG. 10 is a flowchart showing an example of the operation of the printing system 100 after the print button 401 of the application screen 400 shown in FIG. 4A is tapped. For the same processing as the step already described, the same number as the step number already described is assigned, and the description is omitted unless otherwise specified.

The process described in this embodiment is realized by loading the program recorded in the flash memory 2003 into the RAM 2002 and executing the program in the SoC 2001.

If it is determined in the step of S605 that the print plug-in in the invalid state exists, the UI unit 101 displays a warning screen 900 as shown in FIG. 9 (S1005). The warning screen 900 informs the user that there is a print plug-in in the disabled state by displaying the message "There is a print service disabled." Further, the warning screen 900 displays a message and also has a function as a setting screen for changing the enabled / disabled state of the installed print plug-in including the disabled print plug-in.

On the warning screen 900, print plug-in setting buttons 901 and 902 for switching the enabled / disabled state of each installed print plug-in are arranged. When the continuation button 903 on the warning screen 900 is tapped (S1006), it is determined in the next step S1007 whether or not the setting on the warning screen 900 has been changed.

Note that the warning screen 900 may be configured so that the print plug-in setting button is arranged only for the print plug-in in the disabled state.

If it is determined that the setting has been changed in the step of S1007, the process proceeds to the step of S1008. In the step of S1008, the printing system 100 updates the enabled / disabled state of each print plug-in via the print plug-in management unit 104 according to the setting specified on the warning screen 900. After updating the enabled / disabled state of the print plug-in, the process proceeds to step S1004, the UI unit 101 displays the print setting screen 402, and the process ends.

On the other hand, if it is determined in the step S1007 that there is no setting change, or if it is determined in the step S1003 that there is no print plug-in in the invalid state, the UI section is performed in the step S1004 without doing anything. 101 displays the print setting screen 402 and ends the process.

If the "Do not display this message next time" check box is enabled and the continue button 903 is tapped as described on the warning screen 900, the print plug-in that warned on the warning screen 900 It may be configured so that the process of displaying the warning screen by S1005 is not performed from the next time onward.

In Examples 1 to 3, the case where the print plug-in is installed in the mobile terminal 2000 as the disabled state by default has been described. In this embodiment, a method of describing the default startup information in the manifest and controlling the enabled / disabled state of the print plug-in according to the default startup information will be described.

FIG. 11 is a flowchart showing an example of the operation of the printing system 100 when the print plug-in is installed in the mobile terminal 2000.

The process described in this embodiment is realized by loading the program recorded in the flash memory 2003 into the RAM 2002 and executing the program in the SoC 2001.

First, the print plug-in is installed on the mobile terminal 2000 by receiving an instruction to install the print plug-in from the user via the application distribution service on the Internet (S1101). Next, the print plug-in management unit 104 of the print system 100 acquires the information of the manifest file included in the package of the print plug-in (S1102).

FIG. 12 shows an example of a manifest file of the print plug-in 200. The manifest file is a file prepared for each print plug-in. The manifest file 1200 of FIG. 12 contains information on the behavior of the print plug-in 200. In this embodiment, the package name 1201 and the default activation information 1202 are included. The default startup information 1202 specifies the behavior immediately after the installation of the print plug-in, and three setting values of "ON", "OFF", and "AUTO" can be specified.

The three set values will be briefly described. "ON" corresponds to the valid state of Examples 1 to 3, and "OFF" corresponds to the invalid state of Examples 1 to 3. When "ON" is specified in the manifest file, the print plug-in in which the print plug-in management unit 104 is installed is enabled after the print plug-in including the manifest file is installed. On the other hand, when "OFF" and "AUTO" are specified, the installed print plug-in is disabled. However, when "AUTO" is specified, the print plug-in is enabled only at the first printer search. Then, if the printer detected by the print plug-in for which "AUTO" is specified is not selected as the target printer by the user, the print plug-in is changed to "OFF", which is an invalid state.

Next, in the step of S1103, the print plug-in management unit 104 of the printing system 100 determines the default activation information 1202 from the information of the manifest file acquired in S1102. If it is determined in step S1103 that the default activation information is "ON", the process proceeds to step S1104. In the step of S1104, the print plug-in control unit 102 activates the print plug-in installed in the step of S1101, and then proceeds to the step of S1105.

On the other hand, if the default activation information is determined to be "OFF" or "AUTO" in the step S1103, the process proceeds to the step S1105 without doing anything.

In the step of S1105, the print plug-in management unit 104 stores the valid / invalid state of the plug-in in the flash memory 2003 according to the default startup information acquired in S1102, and ends the process.

FIG. 14 is an example of a UI screen for setting the enabled state of the installed print plug-in. The print plug-in activation setting screen 1600 exists for each installed print plug-in and includes the activation setting 1601. The default value of the activation setting 1601 is the enabled / disabled state of the plug-in stored in the flash memory 2003 in the step of S1105. The values that can be set in the enable setting 1601 are "always valid", "disabled", and "automatic", and each set value is "ON" specified in the manifest file activation information 1202 described with reference to FIG. Corresponds to "OFF" and "AUTO". When the setting is changed on the print plug-in activation setting screen 1600, the print plug-in management unit 104 updates the enabled / disabled state setting stored in the flash memory 2003.

FIG. 13 is a flowchart showing an example of the operation of the printing system 100 after the target printer display area 403 is tapped on the print setting screen 402 shown in FIG. 4B.

First, the target printer display area 403 is tapped on the print setting screen 402 (S1301). Then, the print plug-in control unit 102 acquires a list of print plug-ins installed in the mobile terminal 2000 via the print plug-in management unit 104 (S1302).

Next, the print plug-in control unit 102 acquires the setting of the enabled / disabled state of one print plug-in in the print plug-in list via the print plug-in management unit 104 (S1303). In the step of S1304, the print plug-in control unit 102 determines the setting acquired in the step of S1303. If it is determined in the step of S1304 that it is in the "OFF" state, the process proceeds to the step of S1308 without doing anything. If it is determined in the step of S1304 that the state is "AUTO", the process proceeds to the step of S1305, and the print plug-in management unit 104 activates the print plug-in. After that, in the step of S1306, the print plug-in control unit 102 calls the printer search unit of the print plug-in, and proceeds to the step of S1308.

If it is determined in the step of S1304 that the state is "ON", the print plug-in control unit 102 calls the printer search unit of the print plug-in in the step of S1307, and proceeds to the step of S1308.

Next, the print plug-in control unit 102 determines whether or not the print plug-in whose setting has been acquired in the step of S1303 is the last print plug-in in the print plug-in list (S1308).

If it is determined in the step of S1308 that it is the last print plug-in, the process proceeds to the step of S1309. On the other hand, if it is determined that it is not the last print plug-in, the process returns to the step of S1303, and the installed print plug-in is processed until it is determined to be the last print plug-in in the step of S1308. repeat.

In the step of S1309, the detection result receiving unit 105 is in the reception standby state of the detection result notification from the print plug-in. Next, in the step of S1310, it is determined whether or not the detection result receiving unit 105 has reached the timeout. If it is determined that the time-out has not been reached, the detection result receiving unit 105 determines whether or not the detection result notification has been received from the print plug-in in the step of S1311. In the step of S1311, when the detection result receiving unit 105 receives the result notified from the printer search unit of the print plug-in, it is determined that the detection result has been received. When the detection result receiving unit 105 receives the notification of the detection result, the process proceeds to step S1312. In the step of S1312, the package name of the print plug-in for which the print plug-in management unit 104 has returned the detection result and the date and time for returning the detection result are saved in the flash memory 2003. An example of the stored information is shown below.
Print plug-in package name: jp. co. aaa. xxxxxx
Detection result return date and time: 2014-10-10T15: 39: 24 + 00: 00
The above information is managed for each print plug-in and is overwritten each time the detection result is returned. As a result, it represents the date and time when the print plug-in last detected the printer. If the print plug-in has never detected the printer, the date and time when the print plug-in was installed is stored.

Next, the process proceeds to step S1313, and the UI unit 101 updates the printer list screen 702 as shown in FIG. 7B, and proceeds to step S1309.

The processing of S1309 to S1313 is continued until it is determined that the timeout has been reached in the step of S1310, and then the process proceeds to the step of S1314.

In the step of S1314, the print plug-in control unit 102 determines whether or not there is a print plug-in in the print plug-in list that has not been notified of the detection result in the processes of S1309 to S1313. If it is determined in the step of S1314 that there is a print plug-in that has not notified the detection result, the process proceeds to the step of S1315, and the print plug-in whose print plug-in management unit 104 has not detected the printer for a certain period of time Determine if it exists. In the step of S1315, it is possible to determine whether or not the printer has been detected for a certain period of time by determining the date and time for returning the detection result saved in the step of S1312.

Next, in the step of S1315, after the print plug-in management unit 104 determines that the printer has not been detected for a certain period of time is disabled (S1316), the process ends.

On the other hand, in the step of S1314, if it is determined that there is no print plug-in that has not notified the detection result, the process ends without doing anything. Further, even if it is determined in the step S1315 that there is no print plug-in that has not notified the result for a certain period of time, the process ends without doing anything.

FIG. 15 is a flowchart showing an example of the operation of the printing system 100 after the print button 405 of the application screen 400 shown in FIG. 4B is tapped. In this embodiment, the case where the print button 405 is tapped while the printer-A detected by the print plug-in 200 is selected as the target printer will be described as an example.

First, the print plug-in control unit 102 acquires a list of print plug-ins installed in the mobile terminal 2000 via the print plug-in management unit 104 (S1501).

Next, the print plug-in control unit 102 acquires the enabled / disabled state settings of all the print plug-ins via the print plug-in management unit 104 (S1502). In the step of S1503, the setting of the valid / invalid state acquired in the step of S1502 is determined, and the print plug-in management unit 104 disables the print plug-in in which "AUTO" is set other than the print plug-in 200. To.

Next, in the step of S1504, the print plug-in control unit 102 calls the print processing unit 202 of the print plug-in 200, executes the printing process to the target printer, and ends the processing.
