[0008] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the present invention, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the present invention.

[0009] FIG. 1 is a system configuration diagram including an information processing device 100 and a server 110 (external server). In this embodiment, the information processing device 100 is a personal computer (PC), but is not limited to this. For example, the information processing device 100 may be applied to various devices such as a smartphone, a mobile terminal, a printer, a scanner, a camera, or a smart speaker. The information processing device 100 includes a CPU 101, a ROM 102, a RAM 103, a display device 104, an input interface (I / F) 105, and a network I / F 106. The CPU 101 is a processor that controls each component of the information processing device 100 according to a program stored in the ROM 102. The ROM 102 stores a program 107, such as an embedded operating system (OS) or a web browser. The information processing device 100 can be connected to the Internet 152 via a network connection 151. The server 110 can be connected to the Internet 152 via a network connection 153. The network connection 151 and the network connection 153 are, for example, connections using an Ethernet cable or a communication method (Wi-Fi) conforming to the IEEE802.11 series. The network connection 151 and the network connection 153 enable the information processing device 100 and the server 110 to communicate with each other over the Internet 152.

[0010] The server 110 has a CPU 111, a ROM 112, a RAM 113, an input I / F 114, and a network I / F 115. The CPU 111 is a processor that controls each component of the server 110 in accordance with a program stored in the ROM 112. The ROM 112 stores an embedded operating system (OS) and an initial installation guide program 116.

[0011] The printer 120 has a CPU 121, a ROM 122, a RAM 123, a printing unit 124, and a network I / F 125. The CPU 121 is a processor that controls each component of the printer 120 according to a program stored in the ROM 122. The ROM 122 stores an embedded operating system (OS) and a program that controls the printing function. The printing unit 124 is a mechanism that prints on a recording medium such as paper using a recording agent such as ink. In this embodiment, the printing unit 124 prints using an inkjet method, but is not limited to this. It may also print using an electrophotographic method or a thermal dye sublimation method.

[0012] The information processing device 100 can communicate with the printer 120 via a network connection 154. Specifically, the information processing device 100 can send print jobs to the printer 120 and obtain information about the status of the printer 120 by using a printer driver, a printing application program, or the like. The network connection 154 may be a wireless connection or a wired connection. Examples of wired connections include a wired LAN connection and a USB connection. Examples of wireless connections include a connection using a communication method (Wi-Fi) that complies with the IEEE802.11 series.

[0013] <Embodiment 1> In this embodiment, in order for the printer 120 to be able to perform printing normally after delivery, the user must perform an initial installation operation on the printer 120. Therefore, in this embodiment, the information processing device 100 shows the user a specific method for the initial installation operation, thereby improving the user's convenience in understanding the specific method for the initial installation operation.

[0014] FIG. 2 is a flowchart showing the processing executed by the information processing device 100, which is realized by the CPU 101 reading a program stored in the ROM 102 or the like into the RAM 103 and executing it.

[0015] First, the user performs an operation on input I / F 105 of information processing device 100 to start initial installation guidance program 116. Specifically, this operation is an operation on a predetermined site displayed in the web browser of information processing device 100 for displaying specific instructions for initial installation operations. CPU 101 accepts this operation (S201). When this operation is executed, CPU 101 requests initial installation guidance program 116 from server 110 via network connection 151 and acquires initial installation guidance program 116 from server 110 (S202). Then, CPU 101 uses initial installation guidance program 116 to display on display device 104 an area that provides the user with instructions on specific instructions for initial installation operations (hereinafter, guidance display area) on the web browser (S203). Thereafter, CPU 101 accepts various operations from the user while the guidance display area is displayed, and executes processing according to the accepted operation (S204). The display control in S203 and S204 is realized by the CPU 101 reading out the initial installation guide program 116 stored in the ROM 102 or the like into the RAM 103 and executing it.

[0016] The processing of S203 and S204 will be described in detail below. FIG. 3 shows an example of the guidance display area displayed in S203 in this embodiment. FIG. 3(a) includes a main display section 300 and a thumbnail display section 301. The main display section 300 displays an area showing a specific method for performing the initial installation operation. In this embodiment, the main display section 300 displays images showing a specific method for performing the initial installation operation of the printer 120 in a slideshow format, switching between images at predetermined time intervals. In this embodiment, the initial setup operation includes multiple sections. Each section corresponds to one image, and the images displayed on the main display section 300 switch between the corresponding sections in sequence. Thumbnails representing each section are displayed in the thumbnail display section 301. Note that one section may correspond to multiple images. In this case, the images corresponding to one section are switched between and displayed in sequence, and after all the images corresponding to one section have been displayed, the image corresponding to the next section is displayed. In this embodiment, one section corresponds to one step of the initial installation operation. An example of the initial installation operation is the operation of removing tape attached to the printer 120. Examples of sections in this operation include a section for opening the platen cover of the printer 120, a section for pulling out the paper cartridge of the printer 120, and a section for removing tape attached to the printer 120. An example of the initial installation operation is the operation of turning on the printer 120. Examples of sections in this operation include a section for pressing the power button of the printer 120 and a section for connecting the printer 120 to a power source with a cable. An example of the initial installation operation is the operation of loading paper into the printer 120. Examples of sections in this operation include a section for pulling out the paper cartridge of the printer 120 and a section for operating various levers on the paper cartridge of the printer 120.Additionally, the initial installation operation may be, for example, an operation to set an ink tank (ink cartridge) in the printer 120, an operation to supply ink to the printer 120, or an operation to set up communication between the printer 120 and the information processing device 100. Furthermore, by pressing a button (not shown) on the web browser, the display on the web browser may be controlled so that the currently displayed guidance display area is changed to a guidance display area corresponding to another initial setup operation.

[0017] The main display section 300 has a play icon 302, a left icon 304, a right icon 303, a section number 312, and an enlarge icon 305. The thumbnail display section 301 has an array of thumbnails 306 or blank displays 307 (hereinafter referred to as the thumbnail array), a left icon 309, and a right icon 310.

[0018] The play icon 302 is an icon for playing back a process of switching images displayed on the main display unit 300 at predetermined time intervals (playing a slideshow). The left icon 304 is an icon for displaying, on the main display unit 300, an image of a section whose number is one smaller than the section of the image displayed on the main display unit 300. If the section number of the image displayed on the main display unit 300 is 1, the left icon 304 does not need to be displayed. The right icon 303 is an icon for displaying, on the main display unit 300, an image of a section whose number is one larger than the section of the image displayed on the main display unit 300. If the section number of the image displayed on the main display unit 300 is the maximum value, the right icon 303 does not need to be displayed. The section number 312 is an area indicating the section number of the image displayed on the main display unit 300. The enlarge icon 305 is an area for enlarging the guidance display area to the entire display area of ​​the display device 104.

[0019] The thumbnails 306 correspond to images (sections) displayed on the main display unit 300, and display thumbnailized versions of the images displayed on the main display unit 300. When one of the thumbnails 306 in the thumbnail array is selected, the image in the section corresponding to the selected thumbnail 306 is displayed on the main display unit 300. Furthermore, among the thumbnails 306 in the thumbnail array, the thumbnail 306 corresponding to the section of the image currently displayed on the main display unit 300 is marked with a marker 308 to indicate this. In this embodiment, the marker 308 is a thick line surrounding the thumbnail 306, but is not limited to this form and may be various other markers. Furthermore, the thumbnails 306 each include a section number 311 indicating the number of the section to which each thumbnail corresponds. The blank display 307 is an area displayed before the first thumbnail 306 in the thumbnail array, and does not change the display on the main display unit 300 even if an operation is received from the user. The number of thumbnails 306 that can be displayed in the thumbnail array varies depending on the size of the display area of ​​the display device 104, but FIG. 3 shows a state in which a maximum of five thumbnails 306 can be displayed. The left icon 309 and the right icon 310 are icons for switching between thumbnails 306 and blank displays 307 displayed in the thumbnail array. When the left icon 309 is operated, the rightmost thumbnail 306 is removed from the thumbnail array, and a thumbnail 306 or blank display 307 with a section number 311 that is one less than the leftmost section number 311 is included in the thumbnail array. In other words, the order of the thumbnails 306 and blank displays 307 included in the thumbnail array is shifted to the right. When the right icon 310 is operated, the leftmost thumbnail 306 or blank display 307 is removed from the thumbnail array, and a thumbnail 306 with a section number 311 that is one greater than the rightmost section number 311 is included in the thumbnail array. That is, the order of thumbnails 306 and blank displays 307 included in the thumbnail array is shifted to the left.

[0020] As described above, when the play icon 302 is operated, the main display unit 300 starts playing a slideshow. In this embodiment, when slideshow playback starts, the thumbnail display unit 301 disappears from the guidance display area, and only the main display unit 300 is displayed. That is, the guidance display area shown in FIG. 3B is displayed. Then, when a playback stop operation is performed on the main display unit 300 to stop the slideshow playback, the thumbnail display unit 301 is displayed again in the guidance display area. At this time, the marker 308 is displayed on the thumbnail 306 corresponding to the image displayed on the main display unit 300 when the playback stop operation was performed. At this time, the order of the thumbnails 306 and the blank display 307 included in the thumbnail array is shifted so that the thumbnail 306 corresponding to the image displayed on the main display unit 300 when the playback stop operation was performed is positioned in the center of the thumbnail array.

[0021] Furthermore, as described above, when the enlarge icon 305 is operated, the guidance display area is enlarged to the size of the entire display area of ​​the display device 104. In this embodiment, when the play icon 302 is operated in this state and the thumbnail display section 301 disappears from the guidance display area, the main display section 300 is enlarged so that it includes the area where the thumbnail display section 301 was displayed. This causes the image displayed by the main display section 300 to be displayed larger, thereby improving the visibility of the image. Note that the enlargement of the main display section 300 when the thumbnail display section 301 disappears from the guidance display area may be performed not only after the enlarge icon 305 is operated, but also in the state before the enlarge icon 305 is operated.

[0022] The screen including the guidance display area may also include, for example, an area for explaining in text the initial setup operations corresponding to the image displayed on the main display unit 300. It may also include, for example, an area for displaying a video explaining the initial setup operations corresponding to the image displayed on the main display unit 300. When this area is operated, a new web page for playing the video is displayed in the web browser, and the video is played on this web page.

[0023] After the above-described display control is performed, if CPU 101 receives an end operation from the user, such as an operation to close the web browser (S205), CPU 101 ends the display of the guidance display area and ends the process.

[0024] As described above, in this embodiment, the guidance display area displays the operation method of the printer 120. Incidentally, the user operates the printer 120 while viewing the content being reproduced in the guidance display area displayed by the information processing device 100. Therefore, while operating the printer 120, the user may miss the content being reproduced in the guidance display area. Furthermore, if the operation method is complicated, the user may want to rewatch content being reproduced in the guidance display area that the user has already viewed. By using this embodiment, even if the user misses a specific section while operating the printer 120 and takes their eyes off the guidance display area, the user can redisplay an image corresponding to the specific section with a simple operation. Furthermore, the user can redisplay an image corresponding to a section the user wants to rewatch with a simple operation. In this embodiment, since a section number is assigned to each image, the user can easily identify which section they have already viewed or which section they missed. In other words, it becomes easier for the user to identify which section they want to rewatch, improving user convenience.

[0025] <Embodiment 2> In this embodiment, a form will be described in which particularly important or complicated steps among the specific methods of the initial installation operation shown in the guidance display area are highlighted to improve user convenience. Unless otherwise specified, the system configuration of this embodiment is assumed to be the same as the system configuration of the first embodiment.

[0026] FIG. 4 shows an example of the guidance display area displayed in S203 in this embodiment.

[0027] Like FIG. 3(a), FIG. 4(a) includes a main display unit 300 and a thumbnail display unit 301. In FIG. 4(a), thumbnails included in the thumbnail display unit 301 that correspond to sections showing particularly important or complicated procedures are highlighted by adding a marker 401. Note that highlighting of thumbnails corresponding to sections showing particularly important or complicated procedures may be achieved by other methods, such as surrounding the thumbnail with a thick line or changing the color of the thumbnail. Note that in this embodiment, thumbnails corresponding to sections of images currently displayed on the main display unit 300 are also highlighted (by adding a marker 308). Therefore, it is preferable that the method of highlighting thumbnails corresponding to sections showing particularly important or complicated procedures be different from the method of highlighting thumbnails corresponding to sections of images currently displayed on the main display unit 300. Furthermore, highlighting of thumbnails corresponding to sections showing particularly important or complicated procedures is performed even when the image corresponding to the thumbnail is not displayed on the main display unit 300.

[0028] Furthermore, when a thumbnail corresponding to a section showing a particularly important or complicated procedure is selected, the image displayed in the main display section 300 may also be highlighted.

[0029] In this embodiment, the sections indicating particularly important or complicated procedures are sections for setting ink tanks in the printer 120, sections for checking whether the ink tanks have been set correctly in the printer 120, etc., but may also be other sections.

[0030] FIG. 4(b) shows a guidance display area different from that shown in FIG. 4(a). In FIG. 4(b), the guidance display area includes a seek bar 411. In this embodiment, the seek bar 411 is included below the thumbnail display section 301, but this is not limiting. The seek bar 411 corresponds to the overall playback time of the slideshow (or video) displayed on the main display section 300. Note that the seek bar 411 may correspond not to the overall playback time of the slideshow, but to the playback time of the images corresponding to the thumbnails displayed in the thumbnail display section 301. When a slideshow is being played on the main display section 300, a knob or the like may be displayed at a position corresponding to the playback time of the currently played image. Furthermore, by operating and moving the knob by the user, an image with a playback time corresponding to the moved position may be displayed on the main display section 300. For example, by operating the seek bar 411 itself instead of the knob, an image with a playback time corresponding to the operated position on the seek bar may be displayed on the main display section 300. In this embodiment, a position on the seek bar 411 that corresponds to the playback time at which a section showing a particularly important or complicated procedure is displayed is highlighted (marked with a marker 412). Therefore, the user can easily display an image corresponding to a section showing a particularly important or complicated procedure by moving the knob to the highlighted position or operating the highlighted position.

[0031] It is also possible to implement both the highlighting by adding a marker to the thumbnail shown in Figure 4(a) and the highlighting by adding a marker to the seek bar shown in Figure 4(b).

[0032] This allows the user to easily identify a section that indicates a particularly important or complicated procedure, and easily display an image corresponding to the section on the main display unit 300. Consequently, the user can easily review the image corresponding to the section that indicates a particularly important or complicated procedure.

[0033] <Other embodiments> Although the main display unit 300 has been described above as displaying still images in a slideshow format, this is not limiting. A video may also be displayed on the main display unit 300. In this case, the video is divided into sections, and thumbnails representing each section are displayed in the thumbnail display unit 301. That is, when a thumbnail is selected, the video is played from the playback time of the section corresponding to the selected thumbnail. When the play icon 302 is operated, the main display unit 300 starts playing video data, and when playback of one section of video data ends, the video data of the next section is played seamlessly. The thumbnail may also be a frame image of the beginning of a section of the video.

[0034] In the above description, the area showing the specific method of the initial installation operation is displayed on a web browser, but the present invention is not limited to this. The area may be displayed by an application program or the like included in the information processing device 100.

[0035] In the above description, the initial installation guidance program 116 is acquired from the server 110, but the present invention is not limited to this. The initial installation guidance program 116 may be included in an application program or the like that is pre-stored in the information processing device 100.

[0036] In the above description, the operation indicated by the guidance display area was the initial setting operation of the printer 120, but is not limited to this. For example, instead of the initial setting operation, it may be an operation after the initial setting operation is completed (for example, an operation for printing or an operation for communicating with another device). It may also be an operation of various devices other than the printer 120.

[0037] The present invention can also be achieved by supplying a recording medium on which software program code that realizes the functions of the above-described embodiments is recorded to a system or device, and having a computer in the system or device execute the program code stored on the recording medium. In this case, the program code itself read from the recording medium realizes the functions of the above-described embodiments, and the recording medium on which the program code is stored constitutes the present invention.

[0038] Examples of storage media that can be used to supply the program code include flexible disks, hard disks, optical disks, magneto-optical disks, CD-ROMs, CD-Rs, magnetic tapes, non-volatile memory cards, ROMs, and DVDs. [Explanation of symbols]
