Abstract
It is an object to enable a printer to print at a high speed from drawing data including each drawing object of an image, a text, and graphics in the same page and to form print information in which a deterioration of a picture quality is small. An object-unit resolution discriminator discriminates attributes of drawing objects in print data which is formed by a host, discriminates a kind of resolution processing of each drawing object, selects either one of a high resolution rasterizer and a normal resolution rasterizer every drawing object on the basis of the discrimination result, and switches a resolution processing. A page detection/resolution controller switches a resolution mode for the printer driver to draw every page on the basis of the attribute detected by a page parameter discriminator for analyzing the print data and detecting the attributes of the drawing objects of each page.
