PURPOSE:To improve the printing quality by performing the painting-out processing in the subpixel level obtained by fractionizing the resolution of a printer as the output medium and determining an output picture in accordance with the number of continuous painted-out picture elements to minimize the inversion of relations of painting-out width. CONSTITUTION:A printer controller 2 interprets PDL from a host computer 1 and converts it to image data so that it can be outputted to a printer 3. When a character drawing instruction exists in the PDL, vector data in a font ROM 10 is used and a resolution converter is used to generate font bit map data and draws it in a page memory 8. The painting-out processing is performed in the subpixel level obtained by fractionizing the resolution of the output medium, and the output picture is determined in accordance with the number of continuous painted-out picture elements, in the level. |
