Description

  The present invention relates to an information processing apparatus and a control method thereof.

  In recent years, the function of a mobile terminal represented by a mobile phone has become highly functional, and has a function comparable to a PC, such as a Web browsing function.

  Web content displayed on a portable terminal is described in a structured language represented by XHTML (extensible HyperText Markup Language). In some cases, the layout of a Web page is defined by a style sheet such as CSS (Cascading Style Sheet).

  Web content that can be displayed on these portable terminals is often separated from content displayed on a PC display. That is, an image size and a character size are designated in accordance with the function of the display of the mobile terminal, and are displayed using a display application on the terminal side.

  Therefore, when printing from a mobile device, if no settings are made, the image and text size specified for the display of the mobile device will be printed, reducing the size of the image and text on the paper. There was a problem that.

  The CSS described above can also be specified for each accessed medium. The CSS for each medium includes “screen” for a normal PC display, “tty” for a mobile phone, “print” for printing, and the like. For example, when a web page in which “screen” and “tty” are specified is accessed from a mobile phone, web content laid out for the mobile phone by “tty” is displayed.

  In other words, a web page for which “tty” is specified by CSS can be displayed on the mobile phone display without any problem. However, when printing the page, if “print” is not specified, the print page is used. There is no output in the layout. As a result, the print size may be reduced.

In addition, a technique has been proposed in which the structured language received on the printer side is edited according to the size of the paper to be printed and printed (for example, Patent Document 1).
JP 2000-66867 A

  As described above, in a conventional printer, if a print style sheet is not designated, a desired print result may not be obtained. In the case of a printer that analyzes and edits a structured language by itself, the processing load of the printer increases.

  An object of the present invention is to efficiently edit data to be output.

  In order to solve the above-mentioned problem, the present invention is an information processing apparatus, and based on information acquired by an acquisition unit that acquires device information of a device that is a transmission source of data to be output, An editing unit that edits data to be output, and an output unit that outputs data edited by the editing unit.

  Furthermore, the present invention provides a data editing method, wherein the output is based on an acquisition step for acquiring device information of a device that is a transmission source of data to be output, and the information acquired by the acquisition step. And an editing step for editing the power data.

  As described above, according to the present invention, editing is performed according to the device information of the device that is the transmission source of the data to be output, so that the data can be edited efficiently.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a basic system configuration when the present embodiment is applied. Web content displayed on the displays of the portable terminals 101 and 102 is printed by the printer 103 via wireless. Web content is described in XHTML and CSS. The printer 103 can interpret and print the received XHTML and CSS.

  FIG. 2 is a diagram illustrating an example of printing from the mobile terminal 101 to the printer 103 without using the present invention.

  When printing Web content transmitted from a portable terminal, if “print” for printing is not designated as a media-specific CSS, the print result is as shown in FIG.

  This is because the contents described in XHTML are described considering only display display without being conscious of printing. That is, since the display of a normal portable terminal is smaller than the display of a PC, the size of characters, images, etc. is designated small. Therefore, if printing is performed as it is, the printing result will be very small for paper.

  FIG. 3 is a diagram illustrating a block configuration of the printer 103 according to the present exemplary embodiment.

  A wireless I / F 301 and a wired I / F 302 are interfaces for connecting to a HOST such as a mobile phone. A printer control unit 304 performs head control for printing and ink discharge control.

  The communication control program 305 uses a wireless I / F 301 or a wired I / F 302 to perform communication control such as print data and control signal input / output with the HOST. The HOST analysis unit 306 analyzes data written in XHTML and CSS sent from the HOST. A print data storage unit 307 stores print data sent from the HOST. A printing paper identification unit 308 identifies the size of paper to be printed from the printer main body or information specified in advance, and controls the printing range and the like. The print data analysis unit 309 performs rendering for printing based on the contents analyzed by the HOST analysis unit 306. The print data processing unit 310 converts the print data according to the printing paper and performs processing for validating the print result. The CPU 303 controls the entire printer, including printer processing described later. Although not shown in the figure, a ROM (Read Only Memory) stores a table shown in FIGS. 5 to 7, an operation program for operating the printer shown in FIG. The CPU 303 performs processing to be described later according to this program.

  FIG. 4 shows a “mobile terminal profile” transmitted from the mobile terminal to the printer. This may be transmitted together with the print data, or may be transmitted before or after transmission of the print data. If there is an input key or the like on the printer side, it is possible to input from there.

  Various information is stored in the “mobile terminal profile”. The “identifier” is an identifier indicating what type of terminal. From this information, the printer can recognize whether the terminal that requested printing is a mobile phone, a PDA, or another device. “Model” indicates the model name or model number of the mobile terminal. “Resolution” indicates the resolution of the display. Moreover, when the camera is built in the portable terminal, the number of pixels of the camera may be included.

  5 to 7 are tables showing the enlargement ratios of images and fonts for printing display display contents. The printer holds these tables, and when data to be printed is transmitted, the printer refers to these to enlarge images and fonts.

  FIG. 5 is a table showing the aspect ratio of image data obtained from the resolution of the mobile terminal display and the size of the printing paper. For example, when printing on B5 size paper from a portable terminal having a 240 × 320 pixel display, the image data is enlarged and printed at a ratio of D-03.

  FIG. 6 is a table showing font magnifications determined from the resolution of the mobile terminal display and the size of the printing paper. For example, when printing on A4 size paper from a portable terminal having a display of 128 × 160 pixels, printing is performed with a font multiplied by E-18.

  FIG. 7 is a table showing the image size and font size enlargement ratio of each portable terminal for each print paper size. For example, when printing on B5 size paper from a model AAB mobile phone, the enlargement ratio of the image and font is DA-03 and DB-03, respectively. This table is registered in the printer in advance, but when print data is transmitted from an unregistered model, it can be newly registered in the table.

  FIG. 8 is a flowchart relating to processing of the printer when print data is received.

  First, the printer interprets the transmitted XHTML and CSS, and checks whether a CSS for each medium is designated (step S801).

  When the CSS for each medium is designated (Yes in step S801), it is checked whether or not there is a CSS “print” for printing (step S811). If “print” is designated (Yes in step S811), the designated print layout is set (step S812), and rendering processing is performed (step S808). Then, the printing process is performed after the rendering process is completed (step S809). As a result, regardless of whether or not the transmission source of the print data is a portable terminal, it is possible to print content described in XHTML with a size suitable for printing.

  If there is no “print” designation (No in step S811), the process proceeds to S802. Also, when there is no designation of the CSS for each medium (No in step S801), the process proceeds to S802. In step S802, it is checked whether a mobile terminal profile has been received (step S802).

  When the mobile terminal profile is received (Yes in step S802), the profile is read (step S803). Then, it is checked from the “model” information of the read profile whether there is the same registered model (FIG. 7) (step S804).

  If there is the same (Yes in step S804), the image and font enlargement processing is performed according to the size of the printing paper with reference to FIG. 7 (step S810). Then, the process proceeds to S808.

  If there is no same (No in step S804), the image is enlarged according to the size of the printing paper by referring to FIG. 5 from the “resolution” information of the read profile (step S805). Similarly, referring to FIG. 6, a font enlargement process is performed in accordance with the size of the printing paper (step S806). Then, the model and the enlargement ratio of the image / font are additionally registered in FIG. 7 (step S807). As a result, when a print request is subsequently received from a terminal of the same model, printing can be performed at the enlargement rate set previously, and the processing is simplified.

  If the mobile terminal profile has not been received (No in step S802), the printer cannot determine whether it is a print request from a mobile terminal or a print request from a PC or the like. If the print request is from the PC, it is sufficient to continue printing without performing the enlargement process. However, if the print request is from the mobile terminal, if the print is continued as it is, the print result will be as shown in FIG. . Therefore, the printer instructs the user to select whether to continue or stop printing (step S813).

  If it is selected to continue printing (No in step S813), the process proceeds to S808. Thereby, when printing from a PC or the like, printing can be performed without performing special processing. In addition, if the printed matter is desired because it may be small, printing can be performed even with a print request from the portable terminal.

  If it is selected to cancel printing (No in step S813), printing is stopped. Thereby, even when it is not necessary to print, printing is not performed, which is effective for saving paper.

  As described above, according to the present embodiment, the printer can perform printing suitable for the size of the printing paper based on the profile of the print data transmission source terminal even if the printing CSS is not designated. . Further, since editing is performed uniformly based on a table prepared in advance, a suitable print result can be obtained without performing complicated editing processing each time.

  In S801, the printer checks whether there is a CSS for each medium. However, when a CSS is transmitted from the mobile terminal to the printer, the CSS “print” is transmitted only when there is a CSS designated “print”. It may be. As a result, even for content for which a plurality of media-specific CSSs are designated, CSS that is not used for printing is not transmitted, and the transmission path can be used effectively. In addition, since it is not necessary to determine whether or not “print” is specified in S811, the processing can be simplified.

  In the above description, the enlargement ratio of the image and the font is obtained from the tables shown in FIGS. 5, 6, and 7 prepared in advance, and the enlargement process is performed. However, other methods may be used. For example, regarding the aspect ratio of the image, an enlargement ratio suitable for the size of the printing paper may be calculated each time from the “resolution” information of the read profile, and the enlargement process may be performed. Similarly, for the font, an enlargement ratio suitable for the size of the printing paper may be calculated from the “resolution” information each time, and the enlargement process may be performed. As a result, printing suitable for the size of the printing paper can be performed without preparing tables as shown in FIGS. Regarding fonts, printing may always be performed with a fixed font size and pitch between characters regardless of the size of the printing paper. Thereby, processing can be further simplified.

  In the above description, enlargement of an image or a font is given as the editing process, but the editing process is not limited to this. For example, there are a process for reducing the size according to the paper size and a process for editing the color of an image or font according to the color of the paper.

  In the above embodiment, the description has been made using XHTML as the structured language. However, other structured languages such as HTML (HyperText Markup Language) and XML (extensible Markup Language) may be used.

  In the above-described embodiment, the case where printing is performed wirelessly from the mobile terminal to the printer has been described. However, printing may be performed by wire. Further, the output device is not limited to a printer, and may be a copier, a FAX, or other devices.
