Printer system and image processing method, and computer-readable recording medium with a program for making a computer execute the image processing method recorded therein

摘要

A printer system comprises a printer driver that adds drawing-object information for identifying the type of drawing object to print data that is output to a printer. The printer system further comprises a printer controller that selects dither data matching the drawing object based on the drawing-object information added to the print data, performs dithering on the print data, and expands the data to an image.
