A character-data processing method and apparatus enabling registration of font data generated by an external device into an output device even if the data format created by the external device is different from that of the output device. When font data generated by a host computer is sent to a printer, whether or not a 4-byte font identification flag of the font data is effective is judged. If effective, the font data is registered as an effective external character font. If not effective, the endian of the data is converted by rearranging the order of byte-array of the identification flag, and whether or not the font is effective is judged. If effective, the font data is registered while performing endian conversion by rearranging the order of byte-array of font data itself. Thus, difference of endians between the host computer and the printer is offsetted. Regarding bitmap font data, endian conversion is performed such that the MSB side bit and the LSB side bit are exchanged. Thus, in a case where the endians of the host computer and the printer are different, the font data generated by the host computer can be used by the printer.
