PURPOSE:To output a character pattern at a high speed even while reducing a memory quantity shared by font data. CONSTITUTION:Upon the receipt of print data from a host computer 120, the data are stored in a page buffer memory 104. When a font pattern corresponding to the character code stored in the page buffer memory 104 is extracted from a font memory 103, a flag stored in a relevant area in the font memory 103 is checked to discriminate whether or not an object character pattern is compressed. When the compressed pattern is discriminated, after the pattern is expanded and expanded in a bit map memory 105. |
