Printer control system for controlling printers differing from each other in dot density

摘要

A printer control system receives ruled line data for the entire printing region with respect to the row direction included in ruled line print data, and image data included in image print data in a plurality of blocks from a host system, accumulates the blocks of the ruled line data and those of image data until all the ruled line data and all the image data are received, and then converts the print dot density of the accumulated ruled line data and image data into a print dot density matching an internal printer thereof. Therefore, the ruled line print data and the image print data are printed correctly without dislocation with respect of the row direction.
