  If it is determined in S140 that there is a character code not yet targeted among the character codes indicated in the target print data, the character drawing means 28a executes the processing of S136.

  If the character drawing means 28a determines in S134 or S140 that there is no character code not yet targeted among the character codes indicated in the target print data, the character drawn in S133, S138 or S139 is recorded by the printer 24. Printing is performed on the medium (S141), and the operation illustrated in FIG. 6 ends.

  As described above, when the document includes characters corresponding to the character code used only in a specific language, MFP 20 determines this specific language as the language of the document (S 161 and S 163). The accuracy of the determination of the language of the document according to the print data can be improved. Therefore, MFP 20 can improve the appropriateness of the character to be drawn according to the character code indicated in the print data.

  The MFP 20 determines the language of the document based also on the feature of the document obtained by text mining the document (S 161 and S 163), so the accuracy of the determination of the language of the document according to the print data can be improved. Therefore, MFP 20 can improve the appropriateness of the character to be drawn according to the character code indicated in the print data.

  When the MFP 20 extracts a plurality of languages having the possibility of the language of the document based on the features of the document (YES in S162), the setting language of the computer 30 that generated the print data and the electronic device that generated the print data Since the language of the document is determined based on at least one of the time zone (S166, S169, and S171), the accuracy of the determination of the language of the document according to the print data can be improved. Therefore, MFP 20 can improve the appropriateness of the character to be drawn according to the character code indicated in the print data.

  In the present embodiment, MFP 20 determines the language of the target document based on the characteristics of the target document (S 161 and S 163), determines the language of the target document based on the setting language of computer 30 (S 166), The determination method of the language of the target document, that is, the determination of the language of the target document based on the time zone of S (S169 and S170) and the determination of the language of the target document based on the default language information 27b (S172) It is executed with priority. However, the MFP 20 may execute only one of these determination methods, or may execute by combining only two or only three of these determination methods.
