Abstract:
A band plotting processing unit analyzes input data to plot in pixel units an image of RGB data corresponding to a character image to be printed, analyzes the input data to generate micropixel RGB data of a low resolution and micropixel shape information (DOT information) of a high resolution. The low resolution image is then converted to a high resolution output image based on the RGB data, the DOT information, and the micropixel RGB data stored in a main memory.
