Description

  The present invention relates to a printing system and a printer used therefor, and in particular, transmits a character code by Unicode that allows characters in a plurality of languages to be used in a common character set from a host computer to a printer. It is suitable for use in a printing system that executes printing of a character string using font data.

  2. Description of the Related Art Conventionally, a printing system in which a host computer and a printer are connected and print data such as a document created by the host computer is transmitted to the printer for printing is widely used. In this type of printing system, print data including a character code obtained by encoding a character is transmitted from a host computer to a printer, and printing is executed by specifying a font to be used.

  By the way, with recent globalization, an increasing number of host computers adopt Unicode that allows characters in a plurality of languages to be used in a common character set as character codes used for screen display. Along with this, printers equipped with fonts of a plurality of languages corresponding to Unicode have recently been used.

  Unicode has more than 1 million code points for languages around the world. Among these, there are those in which characters having different character shapes and fonts are associated with the same character code on Unicode. For this reason, when printing a character based on the character code, it is necessary to specify which country's font is used.

  However, when using a printer that does not have an operation interface or a printer that has only a few operation buttons and dip switches related to specific dedicated functions (no operation interface such as a keyboard or touch panel), the font to be used is Cannot be specified. For this reason, in such a printer that does not have an operation interface sufficient for the user to specify a font, the font is specified and printed in accordance with the priority order set in advance in the printer. In this case, the character corresponding to each character code is printed in the first priority font, but the character code that is not associated with the first priority font is printed in the next priority font.

  Regarding the priority order of languages used for drawing character strings on the display screen, character strings are drawn based on a font priority list in which the language used by the user is given the highest priority and the default language is given the next priority. There is known an information processing apparatus configured to perform the above (see, for example, Patent Document 1).

  In addition, the processing target character is determined from the first character of the character string in order, starting with the first character of the character string, to determine whether or not the language-specific character code corresponding to Unicode character data is only one. Also known is an information processing device designed to specify the language corresponding to the language of the selected language-specific character, or the language corresponding to the local language set as the default value if no language-specific character is found in the character string. (For example, refer to Patent Document 2).

Japanese Patent Laid-Open No. 2006-71668 JP 2007-172387 A

  Each of the techniques described in Patent Documents 1 and 2 discloses a font designation method used when displaying a character string in an information processing apparatus. On the other hand, as described above, the fonts used when printing with the printer are specified according to the priority order set in advance in the printer. For this reason, a printer that does not have a sufficient operation interface for designating a font has a problem that a font to be used for printing cannot be arbitrarily designated.

  The present invention has been made to solve such a problem. Even in a printer that does not have an operation interface sufficient for a user to specify a font, fonts of a plurality of languages corresponding to Unicode are used. It is an object to be able to arbitrarily specify a font to be used for printing from among them.

  In order to solve the above-described problem, in the present invention, a command for setting the priority order of font data in a plurality of languages possessed by the printer is transmitted from the host computer to the printer. In the printer, the priority order of the font data used for printing is set according to the command sent from the host computer, and the font data of any language is used in the print data based on the set priority order. A document including characters corresponding to the character code to be printed is executed.

  According to the present invention configured as described above, even if the printer does not have a sufficient operation interface for designating the font to be used for printing, the host computer can send a command to the printer to transmit the command to Unicode. It is possible to set the priority order of the font data of a plurality of languages corresponding to the printer. In the printer, printing is executed using font data of any language according to the priority order set as described above. As a result, even for a printer that does not have an operation interface sufficient for the user to specify a font, it is possible to arbitrarily specify a font to be used for printing from a plurality of fonts corresponding to Unicode. become.

(First embodiment)
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of a printing system according to the first embodiment. As shown in FIG. 1, the printing system according to the first embodiment includes a host computer 100 and a printer 200 that receives print data from the host computer 100 and executes printing.

  The host computer 100 is, for example, a stationary POS terminal, and is connected to the printer 200 by a USB (Universal Serial Bus) cable 300. The host computer 100 may be a portable POS terminal (smart phone, tablet terminal, etc.), and may be connected to the printer 200 via a wireless network such as a wireless LAN or Bluetooth (registered trademark). Although the host computer 100 is a POS terminal here, the present invention is not limited to this.

  In the present embodiment, the host computer 100 transmits to the printer 200 a character code based on Unicode in which characters in a plurality of languages can be used in a common character set. For example, the host computer 100 is a terminal in which an application corresponding to Unicode is installed, generates print data including a character code by Unicode in the application, and transmits the print data to the printer 200.

  The printer 200 is a POS printer that is connected to a host computer 100 such as a POS terminal and prints a receipt or the like. Although the printer 200 is a POS printer here, the present invention is not limited to this.

  The printer 200 of the present embodiment stores font set data (hereinafter referred to as “font data” or simply “font”) in a plurality of languages corresponding to Unicode, and print data including character codes by Unicode is stored in a host computer. Receive from 100 and execute printing. At this time, the printer 200 executes printing using font data in a language selected according to a preset priority order from among font data in a plurality of languages.

  In the first embodiment, the priority order of fonts (priority order of languages used) that determines which language fonts are used for printing in the printer 200 is designated by the host computer 100 and includes the designated contents. By sending the received command to the printer 200, the priority order of the fonts is set in the printer 200. Once the font priority order is set for the printer 200, the priority order setting does not change until the next command is sent from the host computer 100 to the printer 200.

  Whenever the printer 200 receives print data from the host computer 100, the printer 200 uses the character code included in the print data and the font data of the language selected according to the font priority set as described above. Print the document that contains the characters corresponding to the code. When the print data includes information (graphics, images, etc.) other than the character code, the printer 200 prints a document including information such as the graphics and images in addition to the characters. Hereinafter, for the sake of simplicity, only the printing of characters will be referred to.

  FIG. 2 is a diagram illustrating a hardware configuration example of the host computer 100. As shown in FIG. 2, the host computer 100 includes a CPU 101, a ROM 102, a RAM 103, a non-volatile memory 104 such as a flash, a hard disk 105, a USB communication unit 106, an operation unit 107, and a display unit 108 as its hardware configuration. Yes.

  The CPU 101 controls the operation of the host computer 100 while using the RAM 103 as a work memory in accordance with a program stored in the ROM 102, the nonvolatile memory 104, or the hard disk 105. The hard disk 105 stores various programs and data. The data stored in the hard disk 105 includes print data.

  The USB communication unit 106 performs data communication with the printer 200 via the USB cable 300. For example, the USB communication unit 106 transmits print data generated by the host computer 100 to the printer 200. In addition, the USB communication unit 106 transmits a command for setting the priority order of the font designated by the host computer 100 to the printer 200 to the printer 200.

  The operation unit 107 is for a user to perform operations related to print data generation and print instructions, font priority designation, and settings for the printer 200, and includes a keyboard and mouse, a touch panel, or the like. . The display unit 108 is for displaying a document relating to print data, a font priority designation screen, and the like, and is configured by, for example, a liquid crystal display or an organic EL display.

  FIG. 3 is a diagram illustrating a hardware configuration example of the printer 200. As shown in FIG. 3, the printer 200 includes a CPU 201, a ROM 202, a RAM 203, a non-volatile memory 204 such as a flash, a USB communication unit 205, and a printing unit 206 as hardware configurations. The printer 200 does not include an operation unit or a display unit for a user to specify a font, and the printer 200 cannot set the priority order of fonts by itself.

  The CPU 201 controls the operation of the printer 200 while using the RAM 203 as a work memory in accordance with a program stored in the ROM 202 or the nonvolatile memory 204. For example, the CPU 201 controls execution of printing based on print data transmitted from the host computer 100. The CPU 201 also sets the priority order of fonts based on a command transmitted from the host computer 100.

  The USB communication unit 205 performs data communication with the host computer 100 via the USB cable 300. For example, the USB communication unit 205 receives print data generated by the host computer 100. Further, the USB communication unit 205 receives a command for setting the priority order of the font designated by the host computer 100 to the printer 200. Information regarding the priority order of the fonts set according to the command is stored in the nonvolatile memory 204.

  The printing unit 206 receives a print execution instruction from the CPU 201 and executes print processing based on the print data. That is, the printing unit 206 executes printing of a character string represented by the character code based on the character code included in the print data received from the host computer 100. Here, the printer 200 prints a character string composed of a character code represented by Unicode using font data of a language selected in accordance with a preset priority order of fonts.

  FIG. 4 is a diagram illustrating a functional configuration example of the printing system according to the first embodiment. As shown in FIG. 4, the host computer 100 includes a priority order designation unit 11, a command output unit 12, a print data generation unit 13, and a print data transmission unit 14 as functional configurations. The printer 200 includes a command input unit 21, a priority setting unit 22, a print data receiving unit 23, a print execution unit 24, and a font data storage unit 25 as functional configurations.

  Here, each of the functional blocks 11 to 14 of the host computer 100 is realized by operating a program stored in the ROM 102, the nonvolatile memory 104, or the hard disk 105 in accordance with the control of the CPU 101 shown in FIG. This program is, for example, a part of an application program installed in the host computer 100. Note that a program that realizes the functions of the priority specification unit 11 and the command output unit 12 and a program that realizes the functions of the print data generation unit 13 and the print data transmission unit 14 may be configured separately.

  Each functional block 21 to 24 of the printer 200 is realized by operating a program stored in the ROM 202 or the non-volatile memory 204 according to the control of the CPU 201 shown in FIG. The font data storage unit 25 is configured by the ROM 202 or the nonvolatile memory 204 of FIG. Alternatively, the font data storage unit 25 may be configured by another storage medium such as a hard disk.

  The priority order designation unit 11 of the host computer 100 designates the priority order of font data of a plurality of languages possessed by the printer 200 through an operation performed by the user on the operation unit 107. What kind of user operation is used to specify the priority order is arbitrary. For example, the priority designation unit 11 causes the display unit 108 to display a plurality of patterns indicating the priorities that can be designated on the screen, and sets the priority based on a user operation that designates one of the plurality of patterns. It is possible to specify.

  For example, it is assumed that the printer 200 stores font data in four languages, Japanese, Chinese, Taiwanese, and Korean, in the font data storage unit 25. In this case, the priority specification unit 11 specifies the priority of the four languages. In the case of four languages, there are a total of 24 combinations of priorities (4 × 3 × 2 × 1 = 24). As shown in FIG. 5, the priority order specifying unit 11 displays a list of the 24 combinations of priority orders on the display unit 108, and designates the priority order of fonts by allowing the user to select one of the patterns. .

  Alternatively, the priority specification unit 11 may specify the priority order based on a user operation that specifies the priority order of a plurality of languages one by one. For example, as shown in FIG. 6, the priority specification unit 11 displays on the display unit 108 input fields in which languages can be input one by one from the first priority to the fourth priority, and Japanese, Chinese are displayed in each input field. The font priority order is specified by allowing the user to input Japanese, Taiwanese, and Korean one by one. In each input field, a language may be input as text, or a pull-down menu may be displayed so that any one of four languages can be selected.

  When the languages are specified one by one in order from the first priority as shown in FIG. 6, it is possible that the user does not have to specify all of them until the fourth priority. For example, when the priority order specifying unit 11 specifies the priority order of a predetermined number of languages (four languages of Japanese, Chinese, Taiwanese, and Korean in this example), the priority order specifying unit 11 does not satisfy the predetermined number. When a priority order is specified for a language based on a user operation, the priority order for another language may be specified in the default order following the priority order for the language specified based on the user operation.

  For example, the default priority order is determined as Japanese → Chinese → Taiwan → Korean. In this case, it is assumed that the user specifies Chinese as the first priority language, specifies Taiwanese as the second priority language, and does not specify the third priority language and the fourth priority language. In this case, the priority designation unit 11 automatically designates the third priority as Japanese and the fourth priority as Korean for the remaining Japanese and Korean according to the default priority. In this way, since there is no need to designate the priority order for the font that the user does not need to care about, there is an advantage that the designation can be made easily.

  The command output unit 12 outputs a command for setting the priority order designated by the priority order designation unit 11 to the printer 200 to the printer 200. For example, after the font priority order is designated on the priority order designation screen shown in FIG. 5 or FIG. 6, when the user operates the confirm button at the bottom of the screen, the command output unit 12 displays a command including the information on the designated priority order. Is output to the printer 200.

  In the first embodiment, the command output unit 12 transmits a command to the printer 200 in advance, asynchronously with the timing at which the print data transmission unit 14 transmits the print data to the printer 200.

  The print data generation unit 13 generates print data including an arbitrary character string through an operation performed on the operation unit 107 by the user. In the present embodiment, the print data generation unit 13 generates print data in which a character string is represented by a character code by Unicode. The print data transmission unit 14 transmits the print data generated by the print data generation unit 13 to the printer 200. That is, the print data transmission unit 14 transmits print data including the character code of the character to be printed to the printer 200.

  The font data storage unit 25 of the printer 200 stores font data in a plurality of languages corresponding to Unicode. For example, the font data storage unit 25 stores font data in four languages: Japanese, Chinese, Taiwanese, and Korean.

  The command input unit 21 inputs a command output by the command output unit 12 of the host computer 100. In the first embodiment, the command input unit 21 inputs a command sent asynchronously at a timing different from the print data sent from the host computer 100.

  The priority order setting unit 22 sets the priority order of the language of the font data used for printing in the printer 200 according to the command input by the command input unit 21. In other words, the priority order setting unit 22 stores the priority order information included in the command in the nonvolatile memory 204, thereby setting the priority order of the font designated by the host computer 100 in the printer 200.

  In the first embodiment, the priority order setting unit 22 holds the priority order set according to the command until the command input unit 21 inputs the next command. That is, the priority order information stored in the nonvolatile memory 204 is maintained until a command is next sent from the host computer 100 and rewritten by the priority order setting unit 22.

  The print data receiving unit 23 receives the print data transmitted by the print data transmitting unit 14 of the host computer 100. That is, the print data receiving unit 23 receives print data including a character code by Unicode from the host computer 100.

  Based on the priority set by the priority setting unit 23 (priority information stored in the non-volatile memory 204), the print execution unit 24 stores font data of a plurality of languages stored in the font data storage unit 25. Based on the print data received by the print data receiving unit 23, the document including characters corresponding to the character code included in the print data is printed using font data of any language.

  Here, the print execution unit 24 executes printing for each character code included in the print data by using font data of any language based on a preset priority order. At this time, if the font data corresponding to the character code exists in the first priority language, the print execution unit 24 prints the character using the font data of the first priority language.

  On the other hand, if the font data corresponding to the character code does not exist in the first priority language, the character is printed using the font data of the second priority language. If the font data corresponding to the character code does not exist in the second priority language, the character is printed using the font data of the third priority language. Similarly, if the font data corresponding to the character code does not exist in the third priority language, the character is printed using the font data of the fourth priority language.

  FIG. 7 is a diagram illustrating an example of a document to be printed. FIG. 8 is a diagram showing the correspondence between Unicode and fonts of each language. Note that the kanji characters such as “Sen”, “Science”, “Voucher”, etc. shown in FIG. 8 indicate notation in the font for screen display unified by Unicode regardless of the language, and are not necessarily limited to the printer 200. It does not match the notation of each kanji printed by the fonts that have.

  The document shown in FIG. 7A includes three kanji characters “numbered tickets”. As shown in FIG. 8, the character code (code number) of each kanji according to Unicode is “set” = U + 6574, “reason” = U + 7406, and “ticket” = U + 5238. Any font data in Japanese, Chinese, Taiwanese, or Korean (font data stored in the printer 200) has a character shape corresponding to the Unicode of "same", "reason", and "ticket". Yes. Therefore, in this case, even if the font of any language is set as the first priority, the characters “numbered ticket” can be correctly printed with the unified font.

  On the other hand, the document shown in FIG. 7B includes three kanji characters “▼ Edition No.”. “▼ edition ▲” means a simplified form of “hen”. As shown in FIG. 8, the character code (code number) of each kanji in Unicode is “▼ Edit” = U + 7F16, “No.” = U + 53F7, “Vot” = U + 7968. Regarding “votes”, any font data in Japanese, Chinese, Taiwanese, and Korean has a character shape corresponding to Unicode. However, for “▼ edition ▲”, only Chinese fonts have a character shape corresponding to this Unicode, and “No.” has a character shape corresponding to this Unicode. Only Japanese and Chinese fonts.

  Therefore, in the case of the document shown in FIG. 7B, it is necessary to use a Chinese font in order to correctly print all three characters “▼ Edition No.” with a unified font. For example, if the Japanese font is set to be the first priority, the character code “U + 53F7” for “No.” and the character code “U + 7968” for “vote” have corresponding Japanese character font data. The printing is executed with the Japanese font set to the first priority. On the other hand, for “▼ edition ▲”, since there is no Japanese character font data corresponding to the character code “U + 7F16”, printing is performed with the Chinese font set after the second priority. Is done. For this reason, as in the document shown in FIG. 7B, “▼ edition ▲” is printed with a Chinese font, and “issue tag” is printed with a Japanese font, and the fonts are not unified and are unbalanced. End up.

  On the other hand, when the Chinese font is set to the first priority, all of “▼ Edit”, “No.”, and “Vote” are printed in the Chinese font, and the font is unified. Therefore, when the application installed in the host computer 100 is an application corresponding to Chinese, the priority order specifying unit 11 may designate Chinese as the first priority. The application corresponding to Chinese means an application that uses a character code group assigned to Chinese in Unicode. If the application installed in the host computer 100 is an application that supports Japanese, the priority designation unit 11 may designate Japanese as the first priority.

  As described above, according to the first embodiment, even when the printer 200 does not have an operation unit sufficient for the user to specify a font, and the priority order of fonts cannot be set in the printer 200. The font priority order is designated by the host computer 100 in accordance with the application and specifications of the application, and a command for setting the priority order is transmitted from the host computer 100 to the printer 200. The priority order of the fonts to be set can be freely set.

  Here, an example has been described in which the user of the host computer 100 arbitrarily designates the priority order of fonts used for printing through the priority order designation screen as shown in FIG. 5 or FIG. 6, but the present invention is not limited to this method. . For example, a vendor who designs and develops an application may determine the priority order of fonts in accordance with the use and specifications of the application and incorporate the priority order information in the application in advance. In this way, it is possible to set the priority order of fonts for each application.

  In this case, for example, the priority order specifying unit 11 specifies the priority order of the fonts by reading the priority order information incorporated in the application in response to a user operation instructing the setting of the priority order. Alternatively, when the application is started, the priority designation unit 11 automatically designates the priority order of the fonts by reading the priority order information incorporated in the application, and the command output unit 12 sets the priority order to the printer. A command for setting to 200 may be automatically output to the printer 200.

  As another example, by displaying a priority order designation screen as shown in FIG. 5 or 6 as one of the environment setting screens for setting the operating environment of the application installed in the host computer 100, The priority order may be designated by the priority order designation unit 11. In other words, the priority order of fonts may be set in advance as the operating environment of the application. In this way, it is possible to freely set the priority order of fonts for each application by the operation of the user who uses the printing system, not the company that designs and develops the application.

  FIG. 9 and FIG. 10 are flowcharts showing an operation example of the printing system according to the first embodiment configured as described above. FIG. 9 is a flowchart showing an operation example when setting the priority order of fonts. FIG. 10 is a flowchart illustrating an operation example when executing printing. The flowchart shown in FIG. 9 starts when the user gives an instruction to set the priority order of fonts. Also, the flowchart shown in FIG. 10 is started when execution of printing is instructed by the user.

  First, the operation when setting the priority order of fonts will be described with reference to FIG. The priority order designation unit 11 of the host computer 100 designates the priority order of the font data of the plurality of languages possessed by the printer 200 based on the user operation (step S1). Next, the command output unit 12 outputs a command for setting the priority specified by the priority specifying unit 11 to the printer 200 to the printer 200 (step S2).

  In the printer 200, when the command input unit 21 inputs the command output from the command output unit 12 (step S3), the priority order setting unit 22 stores the priority order information included in the input command in the nonvolatile memory. By storing in 204, the priority order of the language of the font data used for printing is set in the printer 200 (step S4). Thereby, the process of the flowchart shown in FIG. 9 is completed.

  Next, an operation when printing is performed will be described with reference to FIG. The print data generation unit 13 of the host computer 100 generates print data including an arbitrary character string through a user operation on an application installed in the host computer 100 (step S11). The print data transmission unit 14 transmits the print data generated by the print data generation unit 13 to the printer 200 (step S12).

  In the printer 200, when the print data reception unit 23 receives the print data transmitted by the print data transmission unit 14 (step S13), the print execution unit 24 performs the process from step S14 on the basis of the received print data. Print a document containing text and other information (graphics, images, etc.). First, the print execution unit 24 reads information from the top of the print data, and determines whether the read information is a character code (step S14). If it is not a character code, after printing other information (step S15), the process returns to step S14.

  If it is determined in step S14 that the read information is a character code, the print execution unit 24 sets the priority order setting information stored in the nonvolatile memory 204 and the font stored in the font data storage unit 25. With reference to the data, it is determined whether or not there is font data of the language set with the first priority for the character code (step S16). If there is font data of the language set to the first priority, the print execution unit 24 prints the character corresponding to the character code using the font data of the first priority language (step S17). .

  Thereafter, the print execution unit 24 determines whether or not printing based on the print data has been completed (step S18). If the printing has not been completed yet, the process returns to step S14 to read the next information included in the print data and execute the same process. On the other hand, when all the printing based on the print data is completed, the process of the flowchart shown in FIG. 10 ends.

  On the other hand, if it is determined in step S16 that there is no font data for the language set to the first priority, the print execution unit 24 switches the reference target to the next priority language (step S19). In this case, the language is switched to the second priority language. Then, the print execution unit 24 determines whether there is font data in the language set with the second priority for the processing target character code (step S20).

  Here, when there is font data of the language set to the second priority, the print execution unit 24 prints the character corresponding to the character code using the font data of the second priority language ( Step S17). On the other hand, if it is determined that there is no font data in the language set to the second priority, the print execution unit 24 switches the reference target to the next priority language (step S19). In this case, the language is switched to the third priority language.

  Then, the print execution unit 24 determines whether there is font data in the language set with the third priority for the processing target character code (step S20). Here, when there is font data of a language set to the third priority, the print execution unit 24 prints a character corresponding to the character code using the font data of the third priority language ( Step S17). Similarly, the language corresponding to the character code is printed using the font data of the fourth priority language by switching to the fourth priority language as necessary.

  Thereafter, the print execution unit 24 determines whether or not printing based on the print data has been completed (step S18). If the printing has not been completed yet, the process returns to step S14 to read the next information included in the print data and execute the same process. On the other hand, when all the printing based on the print data is completed, the process of the flowchart shown in FIG. 10 ends.

  As described above in detail, in the first embodiment, the host computer 100 designates the priority order of font data in a plurality of languages that the printer 200 has, and transmits a command from the host computer 100 to the printer 200. Thus, the priority order of the font data used for printing is set in the printer 200 in advance. Thereafter, when printing is performed by transmitting print data from the host computer 100 to the printer 200, the font data of any language is used based on the preset priority order, and the character code included in the print data is converted to the character code. A document including the corresponding character is printed.

  According to the first embodiment configured as described above, even if the printer 200 does not have an operation interface for designating a font to be used for printing, the priority order of font data in a plurality of languages corresponding to Unicode is set. The priority order can be set in the printer 200 by designating it on the host computer 100 and transmitting a command from the host computer 100 to the printer 200. In the printer 200, printing is executed using font data of any language according to the priority order set as described above. As a result, even if the printer 200 does not have an operation interface sufficient for the user to specify a font, a font to be used for printing can be arbitrarily specified from among fonts of a plurality of languages corresponding to Unicode. It becomes like this.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. The overall configuration of the printing system according to the second embodiment is the same as that shown in FIG. However, in order to distinguish from the first embodiment, the code of the host computer is 100A, and the code of the printer is 200A. The hardware configurations of the host computer 100A and the printer 200A are the same as those in FIGS. 2 and 3, respectively.

  FIG. 11 is a block diagram illustrating a functional configuration example of the printing system according to the second embodiment. Note that in FIG. 11, those given the same reference numerals as those shown in FIG. 4 have the same functions, and thus redundant description is omitted here. As shown in FIG. 11, the host computer 100A includes a priority specification unit 11, a command output unit 12A, a print data generation unit 13, and a print data transmission unit 14A as functional configurations. The printer 200A includes a command input unit 21A, a priority order setting unit 22A, a print data receiving unit 23A, a print execution unit 24, and a font data storage unit 25 as its functional configuration.

  When the print data transmission unit 14A transmits print data to the printer 200A, the command output unit 12A of the host computer 100A outputs a command to the printer 200A in a mode in which one command is added to the print data. That is, the command output unit 12A issues a command including information on the priority specified by the priority specification unit 11, and supplies the command to the print data transmission unit 14A. The print data transmission unit 14A transmits the command supplied from the command output unit 12A to the printer 200A together with the print data generated by the print data generation unit 13.

  Note that the priority order designation by the priority order designation unit 11 is, for example, the property screen of the printer driver installed in the host computer 100 when the print data transmission unit 14A transmits print data, as shown in FIG. Such priority order designation screen may be displayed. In this way, it is possible to specify the priority order of fonts for each document to be printed. The priority order information specified through the printer driver property screen may be held as the print environment setting information of the printer driver and maintained until the setting is changed next time.

  As another example, as described in the first embodiment, font priority information may be incorporated in an application in advance. In this case, when the print data is transmitted by the print data transmitting unit 14A, the priority order specifying unit 11 reads the priority order information incorporated in the application, thereby specifying the priority order of the fonts.

  FIG. 12 is a diagram illustrating an example of data transmitted from the print data transmission unit 14A to the printer 200A. As shown in FIG. 12, the print data transmission unit 14A is issued by the command output unit 12A at the head of the print data generated by the print data generation unit 13 based on the priority specified by the priority specification unit 11. Append commands. Then, the print data transmission unit 14A transmits the print data with the command added to the head to the printer 200A.

  The print data receiving unit 23A receives print data with a command added to the head. The command input unit 21A inputs, via the print data receiving unit 23A, a command sent in such a manner that one is added to the head of the print data transmitted from the host computer 100A. That is, the command input unit 21A acquires a command added to the head of the print data received by the print data receiving unit 23A. As described above, in the second embodiment, the command output unit 12A of the host computer 100A outputs a command to the printer 200A via the print data transmission unit 14A, and the command input unit 21A of the printer 200A receives the print data reception unit. A command is input via 23A.

  The priority order setting unit 22A is configured so that the print data receiving unit 23A can execute the command input unit 21A via the print data receiving unit 23A, that is, according to the command given to the print data received by the print data receiving unit 23A. Each time the print execution unit 24 prints a document based on the received print data, the priority order of font data used for the print is set. In other words, the priority order setting unit 22A stores the priority order information included in the command acquired from the head of the print data by the command input unit 21A in the nonvolatile memory 204, so that the font specified by the host computer 100A is stored. The priority order of the language used is set in the printer 200A. In the second embodiment, priority information may be stored in the RAM 203 instead of the nonvolatile memory 204.

  FIG. 13 is a flowchart showing an operation example of the printing system according to the second embodiment configured as described above. FIG. 13 shows an operation example when printing is executed. In FIG. 13, the same number as the step number shown in FIG. 10 executes the same process, and therefore, a duplicate description is omitted here. The flowchart shown in FIG. 13 is started when the execution of printing is instructed by the user. Here, it is assumed that the priority order of fonts used for printing has already been set by the priority order specifying unit 11 as the operating environment of the application or the printing environment of the printer driver.

  First, the print data generation unit 13 of the host computer 100A generates print data including an arbitrary character string through a user operation on an application installed in the host computer 100A (step S21). Next, the command output unit 12A issues a command including information on the priority set in advance as the application operating environment or the printer driver printing environment, and supplies the command to the print data transmitting unit 14A. The print data transmission unit 14A adds a command to the head of the print data generated by the print data generation unit 13 (step S22). Then, the print data transmission unit 14A transmits the print data with the command added to the head to the printer 200A (step S23).

  In the printer 200A, when the print data receiving unit 23A receives the print data with the command transmitted by the print data transmitting unit 14A (step S24), the command input unit 21A adds the print data received by the print data receiving unit 23A. The command that has been executed is acquired (step S25).

  Then, the priority order setting unit 22A stores the priority order information included in the command acquired by the command input unit 21A in the nonvolatile memory 204, thereby setting the priority order of the font data used for the current printing. (Step S26). Thereafter, the print execution unit 24 executes document printing based on the print data received from the host computer 100A by the same processing as step S14 and subsequent steps described in FIG.

  As described above in detail, in the second embodiment, when print data is transmitted from the host computer 100A to the printer 200A, the font data used for printing is transmitted by transmitting a command in a mode added to the print data. Is set to the printer 200A each time printing is performed. A document including characters corresponding to the character code included in the print data is printed using the font data of any language based on the set priority.

  According to the second embodiment configured as described above, a command is transmitted from the host computer 100A to the printer 200A even if the printer 200A does not have a sufficient operation interface for designating a font to be used for printing. Thus, the priority order can be set for the printer 200A. In particular, in the second embodiment, the priority order of fonts used for printing can be freely set for each document to be printed by the printer 200A, for example, by specifying the priority order of fonts each time printing is performed on the property screen of the printer driver. Can also be set. Accordingly, there is an advantage that the degree of freedom for arbitrarily designating a font to be used for printing from among a plurality of languages corresponding to Unicode is increased.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to the drawings. The overall configuration of the printing system according to the third embodiment is the same as that shown in FIG. However, in order to distinguish from the first embodiment, the host computer code is 100B, and the printer code is 200B. The hardware configurations of the host computer 100B and the printer 200B are the same as those in FIGS. 2 and 3, respectively.

  FIG. 14 is a block diagram illustrating a functional configuration example of the printing system according to the third embodiment. In FIG. 14, the same reference numerals as those shown in FIG. 4 have the same functions, and therefore redundant description is omitted here. As shown in FIG. 14, the host computer 100B includes a priority designation unit 11B, a print data generation unit 13B, and a print data transmission unit 14B as functional configurations. The printer 200B includes a print data receiving unit 23B, a print execution unit 24B, and a font data storage unit 25 as functional configurations.

  In the third embodiment, a plurality of characters included in one document can be printed using font data of a plurality of languages. For example, as shown in FIG. 15, it is assumed that a document corresponding to two languages, Japanese and Chinese, is printed. The document shown in FIG. 15 includes a Japanese “numbered ticket” and a Chinese “▼ edition ▲ number vote” representing the same meaning. In the third embodiment, for such a document, “numbered ticket” can be printed in Japanese font, and “▼ edition ▲ ticket” can be printed in Chinese font.

  The priority order specifying unit 11B of the host computer 100B specifies the priority order of fonts used for printing characters at one or more arbitrary positions on the document to be printed. For example, in a state where the document to be printed is displayed on the screen of the display unit 108 and the user moves the cursor to the first position of the character string for which the priority order is to be designated, the priority order designation screen as shown in FIG. By displaying, the priority order is specified at an arbitrary position on the document.

  The print data generation unit 13B is configured to provide one or more commands between a plurality of character codes corresponding to the position specified by the priority order specification unit 11B when generating the print data. Is generated. For example, in the example of the document shown in FIG. 15, a command specifying Japanese as the first priority language is added at the beginning of the document, and the character code of “ticket” and the character code of “▼ hen ▲” are added. A command specifying Chinese as the first priority language is added, and a command specifying Japanese as the first priority language is added again immediately after the character code of “vote”.

  The print data transmission unit 14B transmits the print data in which the command is embedded to the printer 200B. In the third embodiment, the print data transmission unit 14B has a function of a command output unit. That is, the print data transmission unit 14B outputs a command to the printer 200B in such a manner that one or more commands are assigned between a plurality of character codes included in the print data transmitted to the printer 200B.

  In the case of a numbered ticket document as shown in FIG. 15, the characters “numbered ticket” and “▼ edition ▲ vote” are fixed and do not always change no matter how many sheets are printed. And “numbered ticket” is printed in Japanese font, and “▼ edition ▲ vote” is printed in Chinese font. Therefore, a trader who designs and develops an application to be installed and used on the host computer 100B may create an application so that a command is automatically incorporated at each position described above when print data is generated.

  In this case, only the command installation position in the print data is determined in advance by the function of the application, and the priority order of the fonts can be arbitrarily designated based on the user operation. Or, in addition to the command installation position, the priority of fonts specified at each position may also be defined in advance as a function of the application by the contractor. In the latter case, when the print data generating unit 13B generates the print data, the priority specifying unit 11B automatically specifies the font priority by reading the priority information incorporated in the application.

  The print data receiving unit 23B of the printer 200B receives print data in which one or more commands are assigned between a plurality of character codes. As described above, in the third embodiment, the print data receiving unit 23B has the function of the command input unit. That is, the print data receiving unit 23B inputs a command that is sent in such a manner that one or more character codes are added between a plurality of character codes included in the print data transmitted from the host computer 100B.

  When the print execution unit 24B executes printing of a document based on the print data received by the print data reception unit 23B, each time a command appears according to the command assigned to the print data, the font used for the print Execute printing while setting the priority of data. Thus, in the third embodiment, the print execution unit 24B has the function of the priority order setting unit.

  For example, in the example of the document shown in FIG. 15, as described above, a command specifying Japanese as the first priority language is added at the beginning of the document, and the character code of “ticket” and the character of “▼ hen ▲” are added. If a command specifying Chinese as the first priority language is added to the code and a command specifying Japanese is added as the first priority language immediately after the character code of “vote” Only the three characters “▼ Edition No.” are printed with the Chinese font as the first priority, and the other characters are printed with the Japanese font as the first priority.

  FIG. 16 is a flowchart showing an operation example of the printing system according to the third embodiment configured as described above. FIG. 16 shows an operation example when printing is executed. In FIG. 16, the same reference numbers as the step numbers shown in FIG. 10 execute the same processing, and thus the duplicate description is omitted here. The flowchart shown in FIG. 16 is started when the execution of printing is instructed by the user. Here, it is assumed that a command for designating a predetermined priority is added to a predetermined position in the print data by a function incorporated in the application.

  First, the print data generation unit 13B of the host computer 100B generates print data including an arbitrary character string through a user operation on an application installed in the host computer 100B (step S31). Further, the print data generating unit 13B adds a command for designating a predetermined priority order to a predetermined position in the print data (step S32). Then, the print data transmission unit 14B transmits the print data to which one or more commands are added to the printer 200B (step S33).

  In the printer 200B, when the print data receiving unit 23B receives the print data with the command transmitted from the print data transmitting unit 14B (step S34), the print executing unit 24B reads the information from the head of the print data and reads the read information. Is a command (step S35). If the read information is a command, the print execution unit 24B stores the priority order information included in the command in the nonvolatile memory 204, thereby setting the priority order of the fonts used for printing the characters (step) S36). On the other hand, when the read information is not a command, the process of step S36 is not performed.

  Note that when reading information from the beginning of the print data, if the information at the beginning is not a command for designating a predetermined priority, priority is given to printing of character codes that are processed before the command is read. The order is set by another method. For example, it is possible to save the priority order that was last set when printing was previously performed with the same printer 200B, and set the saved priority order. Alternatively, a default priority order may be set for the printer 200B, and the default priority order may be used.

  Thereafter, the print execution unit 24B executes the printing of one character code or other information by the same processing as that after step S14 described in FIG. When printing of one character code or other information is completed, the process returns to step S35, and the same process as described above is executed. Thus, each time a command is read from the print data, the document is printed based on the print data while setting the priority order of the fonts according to the command.

  As described above in detail, in the third embodiment, one or more commands are assigned between a plurality of character codes included in print data transmitted from the host computer 100B to the printer 200B. By outputting to the printer 200B, the priority order of the font data used for printing is set for each designated position in the document. A document including characters corresponding to the character code included in the print data is printed using the font data of any language based on the set priority.

  According to the third embodiment configured as described above, a command is transmitted from the host computer 100B to the printer 200B even if the printer 200B does not have a sufficient operation interface for designating a font to be used for printing. Thus, the priority order can be set for the printer 200B. In particular, in the third embodiment, the priority order of fonts used for printing can be set for each designated position in a document. Accordingly, a plurality of characters included in one document can be printed using font data of a plurality of languages.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to the drawings. The overall configuration of the printing system according to the fourth embodiment is the same as that shown in FIG. However, in order to distinguish from the first embodiment, the code of the printer is 200C. The hardware configurations of the host computer 100 and the printer 200C are the same as those in FIGS. 2 and 3, respectively.

  FIG. 17 is a block diagram illustrating a functional configuration example of the printing system according to the fourth embodiment. In FIG. 17, components having the same reference numerals as those shown in FIG. 4 have the same functions, and thus redundant description is omitted here. As shown in FIG. 17, the host computer 100 has the same functional configuration as that of FIG. The printer 200 </ b> C further includes a delimiter determination unit 26 as a functional configuration thereof, and includes a print execution unit 24 </ b> C instead of the print execution unit 24.

  In the fourth embodiment, as in the third embodiment, a plurality of characters included in one document can be printed using font data of a plurality of languages. For example, in the document shown in FIG. 15, “numbered ticket” can be printed in Japanese font, and “▼ edition ▲ ticket” can be printed in Chinese font.

  The delimiter determining unit 26 determines the delimiter of the character string included in the document based on the arrangement of the plurality of character codes included in the print data received by the print data receiving unit 23. For example, the delimiter determining unit 26 determines that a position where a space character code is present is a delimiter of a character string included in the document. For example, in the case of the document shown in FIG. 15, there is a space between the character string of “numbered ticket” and the character string of “▼ hen ▲ issue vote”. The delimiter determination unit 26 determines the position of this space as a delimiter of the character string. There is also a space between “▼ Edition No.” and “114”. The delimiter determination unit 26 determines that the position of the space is also a character string delimiter.

  The print execution unit 24C performs printing for each character string delimiter determined by the delimiter determination unit 26 based on the priority (priority stored in the non-volatile memory 204) set by the priority setting unit 22. Determine the font data for the language to be used. Then, printing is executed using the font data of the language determined at the beginning of one character string up to the end of the one character string.

  That is, the print execution unit 24C first determines font data of a language to be used for printing based on the priority order at the head of the character string of “numbered ticket”, and uses the font data of the determined language to Execute printing until the end of the "numbered ticket" character string. After that, the font data of the language to be used for printing is again determined based on the priority order at the head of the character string of the next “▼ Edition No.” determined to be delimited by the delimiter determining unit 26 due to the presence of a space, Using the font data of the determined language, printing is executed up to the end of the character string “▼ Edition No.”. The same applies hereinafter.

  Here, it is assumed that Japanese is set as the language of the first priority font by the priority order setting unit 22. In this case, when the document shown in FIG. 15 is printed by applying the first embodiment described above, the “numbered ticket” is printed in a unified Japanese font as described with reference to FIG. As for “▼ edition ▲ vote”, only “▼ edition ▲” is printed in a Chinese font, and “issue” is printed in a Japanese font. As for “▼ Edit”, since there is no Japanese character font data corresponding to the character code, printing is executed with the Chinese font set after the second priority. This is because there is Japanese character-shaped font data corresponding to the character code of “No. form”, and printing is executed with the Japanese font set to the first priority.

  On the other hand, according to the fourth embodiment, when the character string of “numbered ticket” is printed, the Japanese font data set with the first priority for the first character “alignment” is displayed. Using the determined Japanese font data, printing is executed up to the end of the “numbered ticket” character string. On the other hand, when the character string “▼ Edition” is printed, there is no Japanese font data set to the first priority for the first character “▼ Edit ▲”, so the second priority. Thereafter, it is determined that the Chinese font data set is used, and printing is executed up to the end of the character string “▼ Edition No.” using the determined Chinese font data.

  FIG. 18 is a flowchart showing an operation example of the printing system according to the fourth embodiment configured as described above. FIG. 18 is a flowchart illustrating an operation example when executing printing. An example of the operation when setting the priority order of fonts is the same as the flowchart shown in FIG. Further, in FIG. 18, those given the same number as the step number shown in FIG. 10 execute the same process, and thus the duplicated explanation is omitted here. The flowchart shown in FIG. 18 starts when the execution of printing is instructed by the user.

  In the flowchart shown in FIG. 18, after printing a character corresponding to one character code in step S17, the delimiter determining unit 26 determines whether or not the next character code is a space (step S41). If the next character code is not a space, it means that the character string is still continued. Therefore, the process returns to step S17, and the font data of the language determined in the loop of steps S16, S19, S20 is used as it is. Executes printing related to character codes.

  On the other hand, if it is determined in step S41 that the next character code is a space, it means that the character string has been completed to the end, and the process proceeds to step S18. Here, the print execution unit 24 determines whether or not printing based on the print data has been completed. If the printing has not been completed yet, the process returns to step S14 to read the next information included in the print data and execute the same process. On the other hand, when all the printing based on the print data is finished, the process of the flowchart shown in FIG. 18 is finished.

  According to the fourth embodiment configured as described above, a single command can be provided without providing one or more commands between a plurality of character codes included in print data as in the third embodiment. A plurality of character strings included in a document can be printed using font data of a plurality of languages. In addition, although the priority order of fonts is not designated for each character string, one character string can be printed with a single font.

  In the fourth embodiment, the example in which the configuration of the printer 200C is modified based on the configuration shown in the first embodiment has been described. However, the configuration of the printer 200A shown in the second embodiment is described. In addition, a break determination unit 26 may be further provided, and a print execution unit 24C may be provided instead of the print execution unit 24.

  In the first to fourth embodiments, the example in which all the priorities of a predetermined number of languages (four languages, Japanese, Chinese, Taiwanese, and Korean) are set has been described. It is not limited to this. For example, the priority order may be set to a number less than a predetermined number, and “non-corresponding” may be set for the rest. In this case, the print execution units 24, 24B, and 24C do not execute printing for character codes in which none of the font data of the languages for which priority is set is stored in the font data storage unit 25. Alternatively, after replacing with another character code, printing may be executed using font data of any language based on the priority order. Another character code to be replaced is, for example, “·” or “□”. In this way, when there is no font in the language desired by the user, it is possible to select not to print or to perform dummy printing with another character.

  In addition, the above-described first to fourth embodiments are merely examples of specific embodiments for carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. It will not be. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.

12. The printer according to claim 11, wherein the priority setting unit holds the priority set according to the command until the command input unit inputs a next command. The command input unit inputs the command sent in a manner to give one to the print data transmitted from the host computer,
The priority order setting unit sets the priority order of the language of the font data used for the printing each time the print execution unit executes the printing of the document according to the command given to the print data. The printer according to claim 11, wherein The command input unit inputs the command sent in a mode in which one or more character codes are added between the plurality of character codes included in the print data transmitted from the host computer,
Whenever the command appears according to the command given to the print data when the print execution unit executes printing of the document, the priority order setting unit sets the language of the font data used for the printing. 12. The printer according to claim 11, wherein priority is set. A delimiter determining unit that determines a delimiter of a character string included in the document based on a sequence of the plurality of character codes included in the print data transmitted from the host computer;
The print execution unit determines font data of a language to be used for printing for each delimiter of the character string determined by the delimiter determination unit based on the priority set by the priority setting unit. 14. The printer according to claim 12, wherein printing is performed using font data of a language determined at the beginning of the character string up to the end of the one character string.   The print execution unit replaces the character code in which none of the font data of the languages set with the priority by the priority setting unit is stored in the font data storage unit with another character code. 16. The printer according to claim 11, wherein printing is executed using font data of any language based on the priority set by the priority setting unit.
