Disclosed is a system for driving multiple writing element print heads for serial or full width print engines. This system utilizes charge coupled device techniques for handling analog data for grey level printing, printing element uniformity compensation and delay correction for writing elements in multiple rows, thereby efficiently, in terms of silicon real estate, achieving complex functions not practical with analog and digital circuit techniques.
