Printing process using a plurality of drive signal types

摘要

A maskable drive signal generator selectively generates one of n types of maskable drive signals for each main scan pass, and a drive signal shaping section generates a drive signal to be supplied to ink-expulsion drive elements of a print head by shaping the maskable drive signal according to a print signal. The printing of ink dots on each raster line is completed in n x m main scan passes while employing each of the n types of maskable drive signals m times on each raster line.
