<Software configuration>
≪Terminal device≫
The terminal device 10 according to the present embodiment can be represented by, for example, functional blocks as shown in FIG. FIG. 3 is a functional block diagram of an example of a terminal device according to the first embodiment.

  The terminal device 10 includes a print application 11, a printer driver 12, and an OS 13. The printer driver 12 includes a drawing unit 121, a license determination unit 122, and a data conversion unit 123. The printer driver 12 uses a license management unit 124.

  As described above, the print application 11 is an application that can issue a print instruction for print target data, such as a browser, document creation software, and presentation material creation software.

  The OS 13 is basic software that controls the entire terminal device 10. The OS 13 includes Windows (registered trademark), UNIX (registered trademark), MacOS (registered trademark), and the like. In the present embodiment, the OS 13 of the terminal device 10 is described as a Windows OS as an example.

  The printer driver 12 generates print data based on print target data based on a print instruction from the print application 11. The printer driver 12 can generate print data using an embedded font. The embedded font is a technique for embedding character information and font information of characters included in print target data in print data. By using this embedded font, for example, garbled characters are prevented when print data is displayed on a PC or the like in which font information is not installed. The character information is information representing the contents of characters or character strings such as “A” and “Aiueo”. The font information is information such as font name, character shape, height, width, etc. when displaying character information.

  The drawing unit 121 generates print data from the print target data. The license determination unit 122 determines whether redistribution is prohibited for the font information of characters included in the print target data. The data converter 123 converts the font information characters whose redistribution is prohibited by the license determination unit 122 into a data format (for example, BMP format) that cannot be reused.

  The license management unit 124 manages the license information 1000 of each font information. In the present embodiment, the printer driver 12 includes the license management unit 124, but the present invention is not limited to this. For example, the license management unit 124 may be included in a storage device (license management server) connected to the terminal device 10 via the network N1.

  When the printer driver 12 has the license management unit 124, the license information 1000 unique to the printer driver 12 can be held. On the other hand, if a storage device (license management server) or the like connected to the terminal device 10 via the network N1 has the license management unit 124, a common license for a plurality of printer drivers 12 (or a plurality of terminal devices 10). Information 1000 can be held.

≪License information≫
The license information 1000 according to the present embodiment has a configuration as shown in FIG. 4, for example. FIG. 4 is a diagram for explaining an example of license information.

  In the license information 1000 shown in FIG. 4, the font name and the redistribution permission information are separated by commas and stored in association with each other. The license information 1000 is information indicating whether the font information is protected by a license. For example, in the first line of the license information 1000, the font name “Font1” is stored in association with redistribution permission information “redistribution OK” indicating that redistribution is permitted. Similarly, the second line stores the font name “Font2” in association with the redistribution permission information “redistribution NG” indicating that redistribution is prohibited, and the third line stores the font name “Font3”. Is stored in association with redistribution permission information “redistribution OK” indicating that redistribution is permitted. Note that redistribution is permitted indicates that redistribution of font information corresponding to the font name is permitted, while redistribution is prohibited indicates that the font information corresponding to the font name. Indicates that redistribution is prohibited.

<Details of processing>
Next, details of processing of the printing system 1 according to the present embodiment will be described. FIG. 5 is a sequence diagram illustrating an example of output processing according to the first embodiment.

  In the following description, it is assumed that the user has issued a print instruction for print target data such as document data including characters from the print application 11. Note that the processes in steps S11 to S20 below are repeatedly executed according to the number of characters (or character strings) included in the print target data.

  In step S <b> 11, the print application 11 instructs the OS 13 to draw characters included in the print target data. More specifically, the print application 11 instructs the GDI (Graphics Device Interface) that is a part of the OS 13 to draw characters included in the print target data. The drawing instruction here can be performed by the print application 11 calling an API (Application Programming Interface) such as a TextOut function based on the Windows print architecture. Hereinafter, the information regarding the character related to the drawing instruction included in the print target data is represented as “character drawing data”. The character drawing data includes character information that is information representing the contents of the character or character string, and font information that includes information such as the font name and the character shape, height, and width when displaying the character information. . As described above, the character drawing data is information in a vector format represented as a set of a plurality of information (parameters).

  In step S <b> 12, the OS 13 instructs the drawing unit 121 of the printer driver 12 to draw character drawing data. More specifically, the GDI, which is a part of the OS 13, instructs the drawing unit 121 of the printer driver 12 to draw character drawing data. The rendering instruction here can be performed by the GDI calling a DDI (Device Driver Interface) function such as the DrvTextOut function of the printer driver 12 based on the Windows printing architecture.

In step S13, the drawing unit 121 specifies the font name of the font information included in the character drawing data. This font name can be specified as follows.
(1) First, the pointer of the FONTOBJ structure designated as the argument of the DrvTextOut function that has instructed the rendering in step S12 is designated as the argument of the FONTOBJ_pifi function.
(2) Then, a pointer to the IFIMETRICS structure can be obtained.
(3) The font name of the font information included in the character drawing data is stored in the member dpwszFaceName of the IFIMETRICS structure, and the font name can be specified.

  In step S <b> 14, the drawing unit 121 sends a license confirmation request including the font name specified in step S <b> 13 to the license determination unit 122.

  In step S <b> 15, the license determination unit 122 acquires the license information 1000 from the license management unit 124.

  In step S16, the license determination unit 122 is permitted to redistribute the font information included in the character drawing data based on the license information 1000 acquired in step S15 and the font name specified in step S13. It is determined whether or not.

  For example, if the font name specified in step S13 is “Font2”, the license determination unit 122 is prohibited from redistributing the font information related to the font name based on the license information 1000 in FIG. Is determined. On the other hand, for example, when the font name specified in step S13 is “Font1” or “Font3”, the license determination unit 122 re-creates the font information including the font name based on the license information 1000 in FIG. It is determined that distribution is permitted.

  Then, the license determination unit 122 returns the determination result to the drawing unit 121. After that, when the determination result received from the license determination unit 122 is information indicating “redistribution NG”, the drawing unit 121 performs the process of step S17, whereas when the determination result is information indicating “redistribution OK”. The process of step S20 is performed.

  In step S <b> 17, when the determination result received from the license determination unit 122 is information indicating “redistribution NG”, the drawing unit 121 requests the data conversion unit 123 to convert character drawing data.

  In step S <b> 18, upon receiving data conversion from the drawing unit 121, the data conversion unit 123 performs data conversion of character drawing data. The data conversion here is to rasterize character drawing data including character information and font information into a bitmap format using, for example, the EngCreateBitmap function.

  For example, character drawing data having a character string “Aiueo” as character information and a font name “Font2” included in the font information is converted into character drawing data 2000 in a bitmap format as shown in FIG. Thereby, the character drawing data after the data conversion does not have the character information and the font information, and can be distributed without violating the license. In other words, it can be said that the character drawing data after data conversion is character drawing data that cannot be reused. The format after character conversion of character drawing data is not limited to the bitmap format, and may be a data format such as JPEG (Joint Photographic Experts Group) format or PNG (Portable Network Graphics) format.

  In this embodiment, as described above, when redistribution of font information included in character drawing data is prohibited, the font information is converted to a data format that cannot be reused, such as a bitmap format. Not limited. For example, when redistribution of the font information included in the character drawing data is prohibited, the font information included in the character drawing data may be converted into another font information permitted to be redistributed. For example, when the font name of the font information included in the character drawing data is “Font2” (font information for which redistribution is prohibited), the font name “Font1”, which is font information for which redistribution is permitted, The name may be converted to “Font2” or the like.

  In step S19, the drawing unit 121 combines the character drawing data converted in step S18 with the character position according to the drawing instruction in the print target data to generate print data. More specifically, the character drawing data converted into the bitmap format is drawn in the device context as image data.

  In step S20, when the determination result received from the license determination unit 122 is information indicating “redistribution OK”, the drawing unit 121 draws character drawing data including character information and font information in the print target data. The print data is generated by embedding in the character position according to the instruction. That is, for example, when the font name of the font information included in the character drawing data is permitted to be redistributed such as “Font1” or “Font2”, printing using the embedded font based on this character drawing data Generate data.

  An example of the print data generated in steps S19 and S20 is shown in FIG. FIG. 7 is a diagram for explaining an example of output data according to the first embodiment. The print data 3000 as output data is composed of character strings 3100 to 3300. Among these, the character string 3200 is a combination of the character drawing data 2000 shown in FIG. On the other hand, the character string 3100 and the character string 3300 are obtained by embedding character drawing data including character information and font information using an embedded font.

  As described above, in the printer driver 12 according to the present embodiment, when there is a character using font information that is not permitted to be redistributed in the print target data, the data format (for example, the character cannot be reused) Print data is generated after conversion to a bitmap format or the like. On the other hand, if the character included in the print target data is a character using font information that is permitted to be redistributed, the print data is generated by embedding information on the character. This can prevent redistribution that may violate the license for font information that is not permitted to be redistributed.

  In step S <b> 21, the print application 11 instructs the OS 13 to output print data. More specifically, the print application 11 instructs print data output to the GDI, which is a part of the OS 13. The output instruction here can be performed by the print application 11 calling an API such as an EndDoc function based on the Windows print architecture.

  In step S <b> 22, the OS 13 instructs the drawing unit 121 of the printer driver 12 to output print data. More specifically, the GDI that is a part of the OS 13 instructs the drawing unit 121 of the printer driver 12 to output print data. The output instruction here can be performed by the GDI calling DDI functions such as the DrvSendPage function and the DrvEndDoc function of the printer driver 12 based on the Windows printing architecture.

  In step S23, the drawing unit 121 outputs print data. Here, as an output destination of the print data, the print data may be output to the printing apparatus 20 via the network N1, and image processing such as printing may be performed by the printing apparatus 20. Alternatively, the data may be output to the terminal device 10 or a storage device connected to the terminal device 10 via the network N1, and the print data may be stored in the storage device.

[Second Embodiment]
Next, a printing system 1 according to the second embodiment will be described. In the first embodiment, character drawing data including font information prohibited from redistribution is converted into a data format that cannot be reused, such as a bitmap format. Font information is not included. That is, in the first embodiment, character information, font information, and the like are lost. Therefore, in the terminal device 10 of the printing system 1 according to the second embodiment, if there is a character using font information that is not permitted to be redistributed in the print target data, in addition to the first embodiment, Convert to another font information that is allowed to be distributed. Then, the characters based on the converted font information are displayed transparently superimposed on the character drawing data converted into a data format that cannot be reused such as a bitmap format. As a result, font information or the like can be included in the output data while data such as a bitmap format is displayed to the user. In the following description, the same reference numerals as those in the first embodiment are used for the portions having substantially the same functions as those in the first embodiment and the portions for performing the same processing, and the description thereof is omitted.

<Software configuration>
The terminal device 10 according to the present embodiment can be represented by, for example, functional blocks as shown in FIG. FIG. 8 is a functional block diagram of an example of a terminal device according to the second embodiment.

  The terminal device 10 differs from the first embodiment in that the function of the drawing unit 121A is different and that the terminal device 10 further includes a font conversion unit 125.

  The drawing unit 121A generates print data from the print target data. At this time, the drawing unit 121 transparently draws the character drawing data including the font information converted by the font conversion unit 125.

  The font conversion unit 125 converts font information that is not permitted to be redistributed included in the character drawing data into font information that is permitted to be redistributed.

<Details of processing>
Next, details of processing of the printing system 1 according to the present embodiment will be described. FIG. 9 is a sequence diagram illustrating an example of output processing according to the second embodiment.

  In step S31, the drawing unit 121A requests the font conversion unit 125 to convert font information for the character drawing data included in the print target data.

  In step S <b> 32, when the font conversion unit 125 receives a font information conversion request from the drawing unit 121 </ b> A, the font conversion unit 125 acquires the font name of the font information permitted to be redistributed from the license management unit 124.

  For example, the font conversion unit 125 acquires the font names “Font1”, “Font3”, and the like of the font information for which redistribution is permitted. Here, the font conversion unit 125 may acquire a font name set in advance or a font name determined according to a predetermined priority order for the font name of the font information permitted to be redistributed. For example, what is necessary is just to acquire the font name of the other font information similar to the character output by the font information contained in character drawing data.

  In step S33, the font conversion unit 125 converts the font information included in the character drawing data into the font information of the font name acquired in step S32. Hereinafter, the character drawing data converted in step S18 is referred to as “first character drawing data”, and the character drawing data in which font information is converted in this step is referred to as “second character drawing data”.

  In step S34, the drawing unit 121A combines the first character drawing data and the second character drawing data with the position of the character related to the drawing instruction in the print target data to generate print data. At this time, the drawing unit 121A draws the second character drawing data with a transmittance of 100%. That is, the drawing unit 121A transparently overlays the second character drawing data with respect to the first character drawing data.

  An example of the print data generated as described above is shown in FIG. FIG. 10 is a diagram for explaining an example of output data according to the second embodiment. The character string 4100 of the print data 4000 as output data is obtained by transparently overlaying the second character drawing data with respect to the first character drawing data as described above. That is, in the character string 4100, the second character drawing data (characters represented by broken lines in FIG. 10) is transparently transmitted on the first character drawing data (character drawing data 2000 shown in FIG. 6). It is drawn. Therefore, the user can visually recognize the character drawn with the first character drawing data, but cannot visually recognize the character drawn with the second character drawing data. Accordingly, it is possible to prevent a license violation of font information that is not permitted to be redistributed and to include other font information (and character information) that is permitted to be redistributed in the output data. .

<Summary>
As described above, in the terminal device 10 according to the first embodiment, when a character using font information that is not permitted to be redistributed exists in the print target data, the data format in which the character cannot be reused. To generate print data. On the other hand, if the character included in the print target data is a character using font information that is permitted to be redistributed, the print data is generated by embedding information on the character. As a result, it is possible to prevent an act that violates the license, such as generating print data in which font information that is not permitted to be redistributed is embedded and distributing the print data.
