[0021] The print head 145, under the control of the first control unit 150, ejects ink onto a medium to record an image.

[0022] In this embodiment, an inkjet printing device 100 will be described, but the printing device 100 may also be a thermal printer or a SIDM (Serial Impact Dot Matrix) printing device.

[0023] The first control unit 150 is a computer device that includes a first storage unit 160 and a first processor 170. The first storage unit 160 corresponds to a storage unit.

[0024] The first storage unit 160 includes memory such as a RAM (Random Access Memory) and a ROM (Read Only Memory), etc. The first storage unit 160 is also used as a receiving buffer that stores received print data. The first storage unit 160 stores firmware 161 executed by the first processor 170 and a setting file 163. The first storage unit 160 of this embodiment stores a first setting file 163A, a second setting file 163B, and a third setting file 163C as the setting files 163.

[0025] The setting file 163 is a file in which the settings of the printing device 100 are registered. The settings of the printing device 100 include, for example, a password that determines whether or not execution of the update process described below is permitted, and address information set in the printing device 100. In this embodiment, a case where the address information is an IP address will be described. The password and IP address are registered as setting values ​​in the setting file 163.

[0026] The first setting file 163A is a file in which the setting values ​​of the printing device 100 at the time of shipment from the factory are registered. The second setting file 163B is a file in which the setting values ​​of the printing device 100 at a specified time specified by the user through operation of the operation panel 130 or the like are registered. The third setting file 163C is a file that registers the setting values ​​of the printing device 100 currently in use. The first setting file 163A, the second setting file 163B, and the third setting file 163C each contain a password. The password contained in the first setting file 163A is the password registered at the time of factory shipment, and the password contained in the second setting file 163B is the password registered at a specified time. The password registered in the third setting file 163C is the currently registered password.

[0027] The first processor 170 is an arithmetic processing device configured with a CPU (Central Processing Unit) and an MPU (Micro Processor Unit). The first processor 170 may be configured with a single processor, or may be configured with multiple processors. The first processor 170 may be configured to perform processing using a hardware circuit such as an ASIC, or may be configured to perform processing in cooperation with a processor such as a CPU or MPU and a hardware circuit.

[0028] [3. Configuration of information processing device] The information processing device 200 includes a second communication I / F 210, a touch panel 230, and a second control unit 250.

[0029] The second communication I / F 210 includes a communication module such as a LAN card, etc. The first communication I / F 120 is connected to a network 50 (not shown) and performs data communication with devices connected to this network 50.

[0030] The touch panel 230 includes a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel, and a touch sensor disposed on top of the display panel. The display panel and the touch sensor are not shown. The touch panel 230 corresponds to an operation unit and a reception unit. The touch sensor detects a touch operation at a position on the touch panel 230 where the user's finger touches. The touch sensor outputs an operation signal including coordinate information indicating the position of the detected touch operation to the second control unit 250. The touch panel 230 may also include hardware buttons. The touch panel 230 corresponds to a display device. In this embodiment, a case will be described in which the information processing device 200 includes the touch panel 230 as a display device, but the information processing device 200 may also be configured to be externally connected to a display or the like, and to display an image on this display.

[0031] The second control unit 250 is a computer device that includes a second storage unit 260 and a second processor 270.

[0032] The second storage unit 260 includes memories such as RAM and ROM. The second storage unit 260 stores a control program 261 such as an OS (Operating System) executed by the second processor 270. The second storage unit 260 also stores a web browser 263 and a setting change application program 265 as application programs. Hereinafter, the application program will also be referred to as an APP.

[0033] The setting change 265 is an application program executed on the web browser 263, and has the function of changing the settings of the connected printing device 100.

[0034] The second processor 270 is an arithmetic processing unit configured with a CPU or MPU. The second processor 270 may be configured with a single processor or multiple processors. The second processor 270 may be configured to perform processing using a hardware circuit such as an ASIC, or may be configured to perform processing in cooperation with a processor such as a CPU or MPU and a hardware circuit.

[0035] [4. Printing System Operation] Next, the operation of the printing system 1 will be described. The user checks the IP address of the printing device 100 while the printing device 100 and the information processing device 200 are connected to the same network 50. For example, the user operates the operation panel 130 to display the IP address of the printing device 100 or to have the printing unit 140 print the IP address.

[0036] Next, the user starts the web browser 263 and enters the IP address of the printing device 100 that has been confirmed in the URL of the web browser 263 .

[0037] When the IP address of the printing device 100 is entered into the URL of the web browser 263, the second control unit 250 launches the setting change application 265. The second control unit 250, which executes the setting change application 265, connects to the printing device 100 at the entered IP address and displays a password entry screen under the control of the setting change application 265. When a password is entered into the password entry screen, the second control unit 250 transmits the entered password to the printing device 100. The printing device 100 performs password authentication by determining whether the password received from the information processing device 200 matches the registered password included in the third setting file 163C.

[0038] If the received password matches the registered password, the first control unit 150 transmits an authentication completion notification to the information processing device 200. When the second control unit 250 receives the authentication completion notification from the printing device 100, it displays an APP screen 300 that accepts setting changes to the printing device 100.

[0039] FIG. 2 is a diagram showing an example of the APP screen 300. The APP screen 300 includes a first setting field 310, a second setting field 320, a third setting field 330, a fourth setting field 340, and an enter button 350.

[0040] The first setting field 310 is a setting field for setting whether or not to print. In other words, when the password is changed by changing the password or by executing a restoration process, this setting field is for setting whether or not to print the changed password. The first setting field 310 includes a first radio button 311 and a second radio button 313. The first radio button 311 is a button that is selected when the password is to be printed. The second radio button 313 is a button that is selected when the password is not to be printed. After changing the password, the user selects the first radio button 311 by a touch operation when the password is to be printed, and selects the second radio button 313 by a touch operation when the password is not to be printed.

[0041] The second setting field 320 is a field for setting a password. The second setting field 320 includes an input field 321. When changing a password, the user inputs the password to be changed into the input field 321.

[0042] The third setting field 330 is a field for setting an IP address. The third setting field 330 includes a display field 331 and an input field 333. The current IP address of the printing device 100 is displayed in the display field 331. The user inputs the new IP address of the printing device 100 in the input field 333. When changing the IP address, the user inputs the new IP address in the input field 333.

[0043] The fourth setting field 340 is a setting field for the restoration process. In the fourth setting field 340, a selection button 341 and a selection field 343 for the restoration point are displayed. The selection button 341 can be changed between two states: selected and unselected. When the user wants the printing device 100 to execute a restoration process, the user sets the selection button 341 to the selected state by a touch operation. When the user wants the printing device 100 to execute a restoration process, the user sets the selection button 341 to the unselected state by a touch operation. The restoration point selection field 343 displays restoration points that the user can select. In this embodiment, the time that can be selected as a restoration point includes the time when the device was shipped from the factory and the time when the second setting file 163B was created. Hereinafter, the time when the device was shipped from the factory will be referred to as the first time point, and the time when the second setting file 163B was created will be referred to as the second time point.

[0044] When the confirm button 350 is pressed, the second control unit 250 sends a change request to the printing device 100 to change the settings of the printing device 100. This change request includes at least one of the password and IP address accepted on the APP screen 300. Furthermore, if the setting in the first setting field 310 is "Print," the change request includes a print instruction. If the setting in the first setting field 310 is "Do not print," the change request does not include a print instruction.

[0045] Furthermore, when the selection button 341 is in a selected state, the second control unit 250 acquires information about the specified restoration point. Next, the second control unit 250 sends a restoration request to the printing device 100. This restoration request includes the acquired restoration point information. Furthermore, when the setting in the first setting field 310 is "Print," the restoration request includes a print instruction. When the setting in the first setting field 310 is "Do not print," the restoration request does not include a print instruction.

[0046] When the first control unit 150 receives a change request from the information processing device 200, it updates the third setting file 163C based on at least one of the IP address and the password included in the change request. After that, if the change request includes a print instruction, the first control unit 150 causes the printing unit 140 to print the changed password.

[0047] Furthermore, when the first control unit 150 updates the third setting file 163C, the first control unit 150 may cause the printing unit 140 to print a notice indicating that the password or IP address has been changed.

[0048] When printing the password, the first control unit 150 may also print the current date, or the current date and the time when the password or IP address was changed. Furthermore, the first control unit 150 may also print the model name of the printing device 100.

[0049] Furthermore, when the first control unit 150 receives a restoration request from the information processing device 200, it acquires information about the restoration point included in the restoration request.

[0050] When the restore point information is a first time point, which is the time of shipment from the factory, the first control unit 150 executes the restore process based on the first setting file 163A. When the restore point information is a second time point, which is the time point when the second setting file 163B was created, the first control unit 150 executes the restore process based on the second setting file 163B.

[0051] When the first control unit 150 executes the restoration process, it causes the printing unit 140 to print a notice indicating the completion of the restoration process. Furthermore, if the restoration request includes a print instruction, the first control unit 150 causes the printing unit 140 to print the password at the time of restoration in the restoration process. For example, if the time of restoration in the restoration process is the first time point, which is the time of shipment from the factory, the first control unit 150 prints the password at the time of shipment from the factory. Furthermore, if the time of restoration in the restoration process is the time when the second setting file 163B was created, the first control unit 150 prints the password at the time when the second setting file 163B was created.

[0052] When a password is entered in the input field 321 of the second setting field 320, the second control unit 250 may cause the touch panel 230 to display a message inquiring whether or not to print the changed password after the password change is complete. When the second control unit 250 receives an instruction to print the password via a touch operation, it may send an instruction to print the password to the printing device 100.

[0053] FIG. 3 is a flowchart showing the operation of the printing device 100. The operation of the printing device 100 will be described with reference to the flowchart shown in FIG. The first control unit 150 determines whether or not it has received access via the network 50 (step S1). If it has not received access (step S1 / NO), the first control unit 150 waits until it receives access.

[0054] When the first control unit 150 receives an access via the network 50 (step S1 / YES), it transmits a password acquisition request to the access source (step S2).

[0055] Next, the first control unit 150 determines whether or not a password has been received (step S3). If the password has not been received (step S3 / NO), the first control unit 150 waits until the password is received.

[0056] When the first control unit 150 receives the password (step S3 / YES), it determines whether the received password matches the registered password included in the third setting file 163C and performs password authentication (step S4).

[0057] If the received password does not match the registered password, the first control unit 150 determines that the authentication has failed (step S5 / NO), and transmits a password acquisition request again (step S2).

[0058] Furthermore, if the received password matches the registered password, the first control unit 150 determines that the authentication is successful (step S5 / YES), and sends an authentication completion notification to the access source (step S6). In the following, the description will be given assuming that the access source that accessed the printing device 100 is the information processing device 200.

[0059] The first control unit 150 determines whether or not a change request has been received (step S7). If a change request has been received (step S7 / YES), the first control unit 150 updates the third setting file 163C based on the setting values ​​included in the change request (step S8). The setting values ​​include at least one of the changed password and IP address.

[0060] Next, the first control unit 150 determines whether the password has been changed by updating the third setting file 163C in step S8 (step S9). If the password has not been changed (step S9 / NO), the first control unit 150 ends this processing flow.

[0061] Furthermore, if the password has been changed (step S9 / YES), the first control unit 150 determines whether the change request includes a print instruction (step S10). If the change request does not include a print instruction (step S10 / NO), the first control unit 150 ends this processing flow. If the change request includes a print instruction, the first control unit 150 causes the printing unit 140 to print the password (step S11).

[0062] Furthermore, if the first control unit 150 has not received a change request (step S7 / NO), it determines whether or not a restoration request has been received (step S12). If the first control unit 150 has received a change request (step S12 / YES), it acquires restoration point information included in the restoration request (step S13).

[0063] The first control unit 150 determines the time point at which to execute the restoration process based on the acquired restoration point information, and executes the restoration process based on the determined time point (step S14). For example, if the restoration point information is a first time point, which is the time of shipment from the factory, the first control unit 150 executes the restoration process based on the first setting file 163A. On the other hand, if the restoration point information is a second time point, which is the time when the second setting file 163B was created, the first control unit 150 executes the restoration process based on the second setting file 163B.

[0064] Next, the first control unit 150 determines whether the restoration process is complete (step S15). If the restoration process is not complete (step S15 / NO), the first control unit 150 waits until the restoration process is complete. Furthermore, if the restoration process is complete (step S15 / YES), the first control unit 150 restarts the printing device 100 (step S16).

[0065] Next, the first control unit 150 determines whether the restoration request includes a print instruction (step S17). If the restoration request does not include a print instruction (step S17 / NO), the first control unit 150 ends the process without printing the password changed in the restoration process. On the other hand, if the restoration request includes a print instruction (step S17 / YES), the first control unit 150 prints the password changed in the restoration process (step S18) and ends this process flow.

[0066] Furthermore, if the first control unit 150 has not received a restoration request (step S12 / NO), it determines whether or not it has received an end notification (step S19). If the first control unit 150 has not received an end notification (step S19 / NO), it returns to the determination in step S7. If the first control unit 150 has received an end notification (step S19 / YES), it ends this processing flow.

[0067] In the above-described flowchart, the first control unit 150 prints the changed password if the received change request includes a print instruction. As another example, the change request sent by the second control unit 250 to the printing device 100 may not include a print instruction. In this case, the first control unit 150 may determine whether the password has been changed, and if the password has been changed, print the changed password.

[0068] 4 is a flowchart showing the operation of the information processing device 200. The operation of the information processing device 200 will be described with reference to the flowchart shown in FIG. The second control unit 250 starts the web browser 263 in response to the touch operation (step T1). When the IP address of the printing device 100 is input into the URL of the web browser 263 by the user's operation, the second control unit 250 executes the setting change APP 265 (step T2) and accesses the printing device 100 (step T3).

[0069] Next, the second control unit 250 executes the setting change APP 265 to display the APP screen 300 showing a password input field (step T4). The second control unit 250 determines whether a password has been input in the input field (step T5). If a password has not been input (step T5 / NO), the second control unit 250 waits until a password is input.

[0070] When the password is entered (step T5 / YES), the second control unit 250 transmits the entered password to the printing device 100 (step T6). Next, the second control unit 250 determines whether an authentication completion notification has been received from the printing device 100 (step T7).

[0071] If the second control unit 250 has not received the authentication completion notification (step T7 / NO), the process returns to step T5 and prompts the user to enter a password in the entry field again. Furthermore, when the second control unit 250 receives the authentication completion notification (step T7 / YES), it causes the touch panel 230 to display the APP screen 300 that accepts setting changes (step T8).

[0072] Next, the second control unit 250 determines whether or not a touch operation has been received (step T9). If a touch operation has not been received (step T9 / NO), the second control unit 250 waits until a touch operation is received.

[0073] When the second control unit 250 receives a touch operation (step T9 / YES), it determines whether the received touch operation is a setting change operation (step T10). The setting change operation includes, for example, inputting a password into the input field 321, inputting an IP address into the input field 333, selecting the selection button 341, selecting a restore point displayed in the restore point selection field 343, etc.

[0074] If the accepted touch operation is a setting change operation (step T10 / YES), the second control unit 250 changes the display of the APP screen 300 in accordance with the accepted touch operation (step T11), and returns to the determination in step T9.

[0075] When the received touch operation is not a setting change operation (step T10 / NO), second control unit 250 determines whether the received touch operation is an operation on decision button 350 (step T12).

[0076] If the accepted touch operation is an operation of the decision button 350 (step T12 / YES), the second control unit 250 determines whether or not the password or the IP address has been changed (step T13). Specifically, the second control unit 250 determines whether or not the input of the password or the IP address has been accepted in the judgment of step T10.

[0077] If the password or IP address has been changed (step T13 / YES), the second control unit 250 sends a change request to the printing device 100 (step T14). This change request includes at least one of the password and IP address whose input has been accepted. Furthermore, if the setting in the first setting field 310 is "Print," the change request includes a print instruction. If the setting in the first setting field 310 is "Do not print," the change request does not include a print instruction.

[0078] Furthermore, if the password or IP address has not been changed (step T13 / NO), the second control unit 250 determines whether or not a restoration request has been made (step T15). If the selection button 341 in the fourth setting field 340 is selected, the second control unit 250 determines that a restoration request has been made. If there has been no restoration request (step T15 / NO), the second control unit 250 erases the display of the APP screen 300 from the touch panel 230 (step T17) and ends this processing flow.

[0079] Furthermore, if there is a restoration request (step T15 / YES), the second control unit 250 sends the restoration request to the printing device 100 (step T16). This restoration request includes information about the restoration point specified by the user. Furthermore, if the setting in the first setting field 310 is "Print," the restoration request also includes a print instruction. After sending the restoration request to the printing device 100, the second control unit 250 erases the display of the APP screen 300 from the touch panel 230 (step T17), and ends this processing flow.
