ABSTRACT:
Code conversion tables for some major language spheres are stored in a ROM 13 in a printer. Pattern information of all kinds of characters, discriminately represented by their internal codes, are stored in a character generator 15. For code conversion tables for other language spheres than major language spheres, the definition information of each code conversion table is registered in an EEPROM 17 in the printer, from a host device. The definition information of a code conversion table may be prepared by defining the internal codes corresponding to all of the external codes. The definition information may also be prepared in such a way that a code conversion table is selected from among the code conversion tables stored in the ROM 13 and used as a base code conversion table, and only information of the code conversion table which is different from that of the base code conversion table, is defined. Before the printing operation is performed, a CPU 19 prepares a code conversion table in a RAM 7 on the basis of related definition information in the EEPROM 17. During the printing operation, the CPU 19 refers to the code conversion table in the RAM 7.
