PURPOSE:To shorten processing time by executing drawing processing with a bit map buffer formed in a main memory device at the time of transferring graphic data in a printer and collectively transferring graphic data for one page. CONSTITUTION:The pit map buffer corresponding to a bit map for one page of a printer 4 is formed in the main memory device, and at the time of drawing a graphic in the printer 4, graphic data are developed in the bit map buffer 25 and the graphic data for one page are collectively sent to the printer 4. Thereby, the drawing processing of a complicate graphic can be simply and rapidly executed. Since the drawing processing of the buffer 25 can be used in common with drawing processing on a display 2, the constitution of the system can be simplified. |
