Description

The present invention relates to a printing apparatus, a control method , a program, and a storage medium .

In recent years, the Institute of Electrical and Electronics Engineers (IEEE) has defined the faster 802.11ac in addition to 802.11a/b/g/n as an 802.11 standard. 802.11ac/a uses a frequency band of 5 GHz. On the other hand, 802.11b/g uses a frequency band of 2.4 GHz. 802.11n supports both 2.4 GHz and 5 GHz, but the 2.4 GHz frequency band is generally used. General mobile terminals support all of these wireless LAN standards. Some terminals can also set the frequency band they operate in. There are also MFPs (multi-function peripherals) that support both 802.11ac and 802.11n and operate as access points. A method of activating an access point in multiple modes is also known (see Patent Document 1).

JP 2009-100382 A

However, if the access point startup command and the operating frequency command are given on separate screens, there will be frequent screen transitions and complicated operations will be required, which can be time-consuming for the user.

An object of the present invention is to more suitably display a screen for accepting a user operation for selecting a frequency band to be used in direct wireless communication .

The printing device of the present invention is a printing device having a wireless communication function that operates as an access point that performs direct wireless communication with an external terminal without going through an external access point, and has a display unit, a display control means that controls the display unit to display a screen that accepts user operation for selecting a frequency band to be used in the direct wireless communication, the screen including a first option corresponding to a 2.4 GHz frequency band associated with a display element indicating the communication standard IEEE802.11n, and a second option corresponding to a 5 GHz frequency band associated with a display element indicating the communication standard IEEE802.11ac, and a communication control means that controls the printing device to operate as an access point using the 2.4 GHz frequency band when the first option is selected, and as an access point using the 5 GHz frequency band when the second option is selected , based on the user operation accepted via the screen.

According to the present invention, it is possible to more appropriately display a screen for accepting a user operation for selecting a frequency band to be used in direct wireless communication .

The best mode for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the invention as claimed, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

(First embodiment)
1 is a diagram showing an example of the configuration of an information processing system 130 according to a first embodiment of the present invention. The information processing system 130 has a mobile terminal 100, an MFP 110, and an access point 120. The access point 120 is connected to a backbone network of a user environment. The MFP 110 is an image forming device, and can connect the mobile terminal 100 to the access point 120. The mobile terminal 100 wirelessly connects to the MFP 110 as an access point.

Although FIG. 1 shows only one access point 120, in an actual user environment, multiple access points are often permanently installed. The MFP 110 is an information processing device, and may be a personal computer, a mobile terminal, or the like.

The wireless LAN mode is a mode in which the MFP 110 is connected to an access point connected to the user's backbone network in infrastructure mode, while the wired LAN is a mode in which the MFP 110 is similarly connected to the backbone network in a wired manner. The wireless soft AP (access point) mode is a part of the wireless ad hoc mode, and is a mode in which the MFP 110 functions as a pseudo access point to connect the mobile terminal 100 to the MFP 110.

FIG. 2 is a diagram showing an example of the hardware configuration of the MFP 110. The large-scale storage device 211 is, for example, a hard disk. The CPU 202 executes software (programs) stored in the ROM 203 or the large-scale storage device 211. The CPU 202 also performs overall control of each device connected to the system bus 201.

The RAM 204 functions as the main memory and work area of the CPU 202. The external input controller (PANELC) 206 controls instruction input from various buttons or a touch panel (PANEL) 207 provided on the MFP 110. The display controller (DISPC) 208 controls the display of a display module (DISPLAY) 209 composed of, for example, a liquid crystal display. The disk controller 210 controls a large-scale storage device 211. The large-scale storage device 211 is also used as a temporary storage location for images.

The network interface card (NIC) 205 transmits and receives data bidirectionally to and from other network devices or file servers, etc., via the network 200. The wireless communication module (WLAN) 214 performs wireless communication in infrastructure mode or soft AP mode. When the wireless communication module 214 operates in soft AP mode, the MFP 110 operates as an access point and can connect directly to the mobile terminal 100 via wireless communication. The printer 212 is a paper printing unit realized by an electrophotographic method. The printing method does not have to be an electrophotographic method.

The scanner 213 is an image reading unit for reading images printed on paper. The scanner 213 can be equipped with an optional ADF (automatic document feeder) and can automatically read multiple pages of a document.

FIG. 3 is a diagram showing an example of the software configuration of the MFP 110. The OS kernel 320 controls the network setting control unit 300, the UI control unit 310, the Wi-Fi communication control unit 330, and the Ethernet communication control unit 340. The Wi-Fi communication control unit 330 is a module for controlling the wireless communication module 214. The Ethernet communication control unit 340 controls the network interface card 205. The network setting control unit 300 controls the settings of the Wi-Fi communication control unit 330 and the Ethernet communication control unit 340 via the OS kernel 320. The network setting control unit 300 manages the current network settings and manages whether the respective modes of Ethernet (wired LAN), wireless LAN, and wireless soft AP are enabled. In this embodiment, the wired LAN and wireless LAN can only be set exclusively. The wireless soft AP mode can be set independently of the LAN settings. The network setting control unit 300 communicates with the UI control unit 310 to change the UI display, and conversely, controls the network based on operation requests from the UI.

Figure 4 is a diagram showing the screen transition of the local user interface that switches the wired LAN/wireless LAN mode of the MFP 110 and connects to the wireless LAN. The UI control unit 310 first displays a screen 510. On the screen 510, a LAN mode setting button 511 and a wireless LAN setting button 511 are displayed. When the user presses the LAN mode setting button 511, the UI control unit 310 displays a screen 520. The screen 520 is a screen for switching between a wired LAN mode button 522 and a wireless LAN mode button 523, and in the example of the screen 520, the wireless LAN mode button 523 is selected. When the user presses the setting save button 521, the network setting control unit 300 saves the current LAN mode, and the UI control unit 310 displays the screen 510. The wireless LAN setting button 512 on the screen 510 is enabled only when the current LAN mode setting is set to the wireless LAN mode. When the user presses the wireless LAN setting button 512, the UI control unit 310 displays a screen 530 for setting the wireless LAN connection destination.

In the screen 530, the user can input destination information in the SSID input text field 751 and the PSK input text field 752. If the SSID has been connected to once, the stored PSK is displayed in the input text field 751 and 752 with the PSK already input in advance. For security reasons, the actual input value of the PSK is displayed as an asterisk. When the user presses the connect button 533, the Wi-Fi communication connection unit 330 starts the wireless LAN connection process with the current values in the input text fields 531 and 532 as destination information, and the UI control unit 310 displays the screen 540. At this time, the Wi-Fi communication connection unit 330 specifies the frequency and performs the wireless connection process. In the screen 540, the UI control unit 310 displays a pop-up 542 to inform the user that the wireless LAN connection process is in progress. The user can cancel the wireless LAN connection process by pressing the cancel button 541. If the connection is successful, the network setting control unit 300 stores the frequency specified at the time of connection.

Figure 5 is a diagram showing screen transitions of the local user interface for wireless function control of the MFP 110. The UI control unit 310 displays a main menu screen 610. When the user presses the wireless software AP management button 611, if the wireless LAN is connected by 802.11ac, the UI control unit 310 displays a screen 620, which is a wireless software AP startup screen. In this screen 620, the wireless software AP startup button 621 with priority on ease of connection is disabled, and it is not possible to start a wireless software AP with priority on ease of connection. The wireless software AP startup button 622 with priority on speed is enabled, and it is possible to start a wireless software AP with priority on speed. For example, the wireless software AP with priority on ease of connection is 2.4 GHz 802.11n, and the wireless software AP with priority on speed is 5 GHz 802.11ac. When the user presses the wireless software AP startup button 622 with priority on speed, the UI control unit 310 displays a screen 650.

When the user presses the wireless software AP management button 611 on screen 610, if the wireless LAN is not connected, the UI control unit 310 displays screen 630 as a wireless software AP startup screen. On screen 630, the ease of connection-priority wireless software AP startup button 631 and the speed-priority wireless software AP startup button 632 are enabled, so wireless software APs of either frequency can be started. When the user presses the ease of connection-priority wireless software AP startup button 631 or the speed-priority wireless software AP startup button 632, the UI control unit 310 displays screen 650.

When the user presses the wireless software AP management button 611 on screen 610, if the wireless LAN is connected via 802.11n, the UI control unit 310 displays screen 640 as a wireless software AP startup screen. On this screen 640, the wireless software AP startup button 641 that prioritizes ease of connection is enabled, and a wireless software AP that prioritizes ease of connection can be started. The wireless software AP startup button 642 that prioritizes speed is disabled, and a wireless software AP that prioritizes speed cannot be started. When the user presses the wireless software AP startup button 641 that prioritizes ease of connection, the UI control unit 310 displays screen 650.

When the UI control unit 310 displays screen 650, the mobile terminal 100 can connect to the MFP 110. When the user presses the wireless soft AP stop button 651, the network setting control unit 300 stops the wireless soft AP mode, and the UI control unit 310 returns to displaying screen 620, 630, or 640.

As can be seen from the operation of screens 620, 630, and 640, the user can instruct the access point to start up and to set the operating frequency on the same screen, reducing the user's workload.

The wireless soft AP start screens 620, 630, and 640 may explicitly display the frequency and allow the user to select the frequency. Screen 660 is an example screen in which the frequency is displayed as the button name of the local user interface. On screen 660, the UI control unit 310 displays a 2.4 GHz soft AP start button 661 and a 5 GHz soft AP start button 662.

The wireless soft AP start screens 620, 630, and 640 may also explicitly display the names of the wireless LAN standards, allowing the user to select a wireless LAN standard. Screen 680 is an example screen in which the names of the wireless LAN standards are displayed as button names in the local user interface. On screen 680, the UI control unit 310 displays a soft AP start button 681 for 802.11a/b/g/n and a soft AP start button 682 for 802.11ac.

Figure 6 is a flowchart for controlling the start of the wireless soft AP mode of the MFP 110. As a prerequisite, the wireless soft AP mode is stopped at the start of this flowchart. Depending on the configuration of the hardware circuit used for wireless communication, the two Wi-Fi wireless communication infrastructure mode and ad hoc mode may be restricted to using the same frequency channel. The wireless soft AP mode that prioritizes ease of connection is 2.4 GHz 802.11n, and the wireless soft AP mode that prioritizes speed is 5 GHz 802.11ac. When the user presses the wireless soft AP management screen button 611 in Figure 5, the flowchart in Figure 6 starts.

In step S401, the network setting control unit 300 determines whether the connected LAN is in wired LAN mode or wireless LAN mode. If the connected LAN is in wired LAN mode, the network setting control unit 300 proceeds to step S402, and if the connected LAN is in wireless LAN mode, the network setting control unit 300 proceeds to step S403.

In step S402, the network setting control unit 300 enables the soft AP start button 631 with priority on connection and the soft AP start button 632 with priority on speed on the screen 630, and proceeds to step S406. In step S406, the UI control unit 310 displays the screen 630 for starting the wireless soft AP mode. In step S407, the network setting control unit 300 waits until the soft AP start button 631 or 632 is pressed on the screen 630 for starting the wireless soft AP mode. If the soft AP start button 631 or 632 is pressed, the network setting control unit 300 proceeds to step S408. In step S408, the network setting control unit 300 starts the soft AP mode of the frequency of the soft AP start button 631 or 632 pressed on the screen 630 for starting the wireless soft AP mode.

In step S403, the network setting control unit 300 determines whether the frequency of the connected wireless LAN is 2.4 GHz 802.11n. If it is 2.4 GHz 802.11n, the network setting control unit 300 proceeds to step S404, and if it is not 2.4 GHz 802.11n, the network setting control unit 300 proceeds to step S405.

In step S404, the network setting control unit 300 enables the soft AP start button 641 with priority on connectivity on the screen 640, disables the soft AP start button 642 with priority on speed, and proceeds to step S406. In step S406, the UI control unit 310 displays the screen 640 for starting the wireless soft AP mode. In step S407, the network setting control unit 300 waits until the soft AP start button 641 with priority on connectivity is pressed on the screen 640 for starting the wireless soft AP mode. If the soft AP start button 641 with priority on connectivity is pressed, the network setting control unit 300 proceeds to step S408. In step S408, the network setting control unit 300 starts the soft AP mode of the frequency of the soft AP start button 641 with priority on connectivity.

In step S405, the network setting control unit 300 disables the ease of connection-prioritized soft AP start button 621 on the screen 620, enables the speed-prioritized soft AP start button 622, and proceeds to step S406. In step S406, the UI control unit 310 displays the screen 620 for starting the wireless soft AP mode. In step S407, the network setting control unit 300 waits until the speed-prioritized soft AP start button 622 is pressed on the screen 620 for starting the wireless soft AP mode. If the speed-prioritized soft AP start button 622 is pressed, the network setting control unit 300 proceeds to step S408. In step S408, the network setting control unit 300 starts the soft AP mode of the frequency of the speed-prioritized soft AP start button 622.

As described above, the UI control unit 310 is an instruction receiving means, and can issue an instruction to start an access point of a wireless ad-hoc network and an instruction for the operation mode of the access point on the same screen on screens 620, 630, and 640. The network setting control unit 300 is an activation means, and activates the access point in the operation mode instructed by the UI control unit 310. The ease of connection-priority soft AP activation buttons 631 and 641 are a first instruction means for instructing to start the access point in a first operation mode. The speed-priority soft AP activation buttons 622 and 632 are a second instruction means for instructing to start the access point in a second operation mode.

In screen 630, the first operation mode is a connection priority operation mode 631, and the second operation mode is a speed priority operation mode 632. In screen 660, the first operation mode is a first frequency wireless operation mode 661, and the second operation mode is a second frequency wireless operation mode 662. In screen 680, the first operation mode is a first wireless communication network standard operation mode 681, and the second operation mode is a second wireless communication network standard operation mode 682.

In step S401, if the network setting control unit 300 is connected to a wired network, the process proceeds to step S402. In step S402, the UI control unit 310 can give instructions on the screen 630 using the soft AP start button 631 that prioritizes ease of connection and the soft AP start button 632 that prioritizes speed.

In step S403, if the network setting control unit 300 is connected to a 2.4 GHz 802.11n wireless network, the process proceeds to step S404. In step S404, the UI control unit 310 determines that the 2.4 GHz 802.11n soft AP start button 641 on the screen 640 can be used to give instructions, but the 5 GHz 802.11ac soft AP start button 642 cannot be used to give instructions.

According to this embodiment, the user can instruct the access point to start up and the operating frequency on the same screen (screens 620, 630, and 640), reducing the user's workload.

Second Embodiment
The information processing system 130 of the second embodiment has a similar configuration to the information processing system 130 of the first embodiment. Below, differences between the second embodiment and the first embodiment will be described.

Figure 7 is a diagram showing screen transitions of the local user interface for wireless function control of the MFP 110 according to the second embodiment. The UI control unit 310 displays a main menu screen 810. When the user presses the wireless software AP management button 811, if the wireless LAN is connected by 802.11ac, the UI control unit 310 displays a screen 820, which is a wireless software AP startup screen. In this screen 620, the check box 821 for priority on ease of connection is disabled, and it is not possible to start a wireless software AP with priority on ease of connection. The check box 822 for priority on speed is enabled and checked, so it is possible to start a wireless software AP with priority on speed. For example, the wireless software AP with priority on ease of connection is 2.4 GHz 802.11n, and the wireless software AP with priority on speed is 5 GHz 802.11ac. When the user presses the start button 823 with the check box 822 for priority on speed checked, the UI control unit 310 displays a screen 850.

When the user presses the wireless software AP management button 811 on screen 810, if the wireless LAN is not connected, the UI control unit 310 displays screen 830 as a wireless software AP startup screen. On screen 630, the ease of connection priority check box 831 and the speed priority check box 832 are enabled, so wireless software APs of either frequency can be started. The ease of connection priority check box 831 is selected by default, but the user can change this. When the user presses the start button 833 with the check box 831 or 832 checked, the UI control unit 310 displays screen 850.

When the user presses the wireless software AP management button 811 on screen 810, if the wireless LAN is connected via 802.11n, the UI control unit 310 displays screen 840 as a wireless software AP startup screen. On this screen 640, the ease of connection priority check box 841 is enabled and checked, and a wireless software AP with ease of connection priority can be started. The speed priority check box 842 is disabled, and a wireless software AP with speed priority cannot be started. When the user presses the start button 843 with the ease of connection priority check box 841 checked, the UI control unit 310 displays screen 850.

When the UI control unit 310 displays screen 850, the mobile terminal 100 can connect to the MFP 110. When the user presses the wireless soft AP stop button 851, the network setting control unit 300 stops the wireless soft AP mode, and the UI control unit 310 returns to displaying screen 820, 830, or 840.

As can be seen from the operation of screens 820, 830, and 840, the user can instruct the access point to start up and to set the operating frequency on the same screen, reducing the user's workload.

The wireless soft AP start-up screens 820, 830, and 840 may explicitly display the frequency and allow the user to select the frequency. Screen 860 is an example screen in which the frequency is displayed in the check box name of the local user interface. On screen 860, the UI control unit 310 displays a 2.4 GHz soft AP check box 861, a 5 GHz soft AP check box 862, and a start button 863.

The wireless soft AP start-up screens 820, 830, and 840 may also explicitly display the names of the wireless LAN standards, allowing the user to select a wireless LAN standard. Screen 880 is an example screen in which the names of the wireless LAN standards are displayed in the checkbox names of the local user interface. On screen 880, the UI control unit 310 displays a soft AP checkbox 881 for 802.11a/b/g/n, a soft AP checkbox 882 for 802.11ac, and a start button 883.

Figure 8 is a flowchart for controlling the start-up of the wireless soft AP mode of the MFP 110. The prerequisites and restrictions are the same as those in the first embodiment. The wireless soft AP mode that prioritizes ease of connection is 2.4 GHz 802.11n, and the wireless soft AP mode that prioritizes speed is 5 GHz 802.11ac. The user interface of the wireless soft AP start-up screen allows the user to select a frequency using a check box, and to start the soft AP of the frequency selected in the check box using the start button. When the user presses the wireless soft AP management screen button 811 in Figure 7, the flowchart in Figure 8 starts.

In step S701, the network setting control unit 300 determines whether the connected LAN is in wired LAN mode or wireless LAN mode. If the connected LAN is in wired LAN mode, the network setting control unit 300 proceeds to step S702, and if the connected LAN is in wireless LAN mode, the network setting control unit 300 proceeds to step S704.

In step S702, the network setting control unit 300 enables the check box 831 for ease of connection and the check box 832 for speed priority on the screen 830. In step S703, the network setting control unit 300 checks the default check box 831 on the screen 830. On the screen 830, the check box 831 for ease of connection priority is checked, but the check box 832 for speed priority may also be checked. The two check boxes 831 and 832 are mutually exclusive. In step S709, the UI control unit 310 displays the screen 830 for starting the wireless software AP mode. On the screen 830, the user can also change the check. In step S710, the network setting control unit 300 waits until the start button 833 is pressed on the screen 830 for starting the wireless software AP mode, and when the start button 833 is pressed, the process proceeds to step S711. In step S711, the network setting control unit 300 starts the soft AP mode for the frequency of the check box 831 or 832 that is checked on the screen 830 for starting the wireless soft AP mode.

In step S704, the network setting control unit 300 determines whether the frequency of the connected wireless LAN is 2.4 GHz 802.11n. If it is 2.4 GHz 802.11n, the network setting control unit 300 proceeds to step S705, and if it is not 2.4 GHz 802.11n, the network setting control unit 300 proceeds to step S707.

In step S705, the network setting control unit 300 enables and checks the check box 841 for ease of connection on the screen 840. In step S706, the network setting control unit 300 disables the check box 842 for speed on the screen 840. In step S709, the UI control unit 310 displays the screen 840 for starting the wireless soft AP mode. In step S710, the network setting control unit 300 waits until the start button 843 is pressed on the screen 840 for starting the wireless soft AP mode, and when the start button 843 is pressed, the process proceeds to step S711. In step S711, the network setting control unit 300 starts the soft AP mode for the frequency of the check box 841 for ease of connection.

In step S707, the network setting control unit 300 enables and checks the speed priority check box 822 on the screen 820. In step S708, the network setting control unit 300 disables the connectivity priority check box 821 on the screen 820. In step S709, the UI control unit 310 displays the screen 820 for starting the wireless soft AP mode. In step S710, the network setting control unit 300 waits until the start button 823 is pressed on the screen 820 for starting the wireless soft AP mode, and when the start button 823 is pressed, the process proceeds to step S711. In step S711, the network setting control unit 300 starts the soft AP mode for the frequency of the speed priority check box 822.

As described above, screen 830 has check box 831 for selecting an operation mode that prioritizes ease of connection, check box 832 for selecting an operation mode that prioritizes speed, and start button 833 for instructing the access point to start. Start button 833 is a button for instructing the access point to start in the operation mode selected by check box 831 or 832.

In step S701, if the network setting control unit 300 is connected to a wired network, the process proceeds to step S702. In step S702, the UI control unit 310 can select either the ease of connection priority check box 831 or the speed priority check box 832 on the screen 830.

In step S704, if the network setting control unit 300 is connected to a 2.4 GHz 802.11n wireless network, the process proceeds to step S705. In step S705, the UI control unit 310 allows selection of the 2.4 GHz 802.11n check box 841 on the screen 840, but does not allow selection of the 5 GHz 802.11ac check box 842.

According to this embodiment, the user can instruct the access point to start up and the operating frequency on the same screen (screens 820, 830, and 840), reducing the user's workload.
