Abstract
A controller for a Chinese character printer, or the like, includes a pattern buffer into which character pattern data is written by an input control unit transferring the character pattern data from a temporary input buffer. The character pattern data is transferred from the character pattern buffer into a font memory by an output control unit only during a non-printing period, such as during a paper feed, of the printer. Print data, including character codes, are transferred by the input control unit from the input buffer to a page buffer. During a printing period, the output control unit selects character pattern data in the font memory in accordance with the character codes in the page buffer and transfers the corresponding character pattern data to a pattern converting unit which sends appropriate print signal data based on the character pattern data to the printer.
