<p>A dot-matrix printer of the invention uses a font cartridge unit storing in advance character pattern data corresponding to characters other than standard characters. The font cartridge unit comprises a ROM or RAM storing character pattern data in a storage area in units of pages. A CPU sets a given page address in a page address register in the font cartridge unit in the case of dot printing of characters other than standard characters. The CPU reads out desired character pattern data from the storage area of the ROM or RAM corresponding to the preset page address, and stores the readout data in a work memory. A printing mechanism controller controls a printing mechanism including a print head in accordance with the character pattern data stored in the work memory so as to execute dot printing of, e.g., high-density characters other than standard characters.</p> |
