Use of sequential firing to compensate for drop misplacement due to curved platen

摘要

A method and apparatus actuates a line of printing elements to form characters on a recording medium contained on a curved surface of a platen. The printing elements are sequentially actuated, starting with nozzles located furthest from the platen and proceeding towards printing elements located closest to the platen until the actuation of all element has been performed. The line of printing elements can form a printhead which includes a plurality of nozzles arranged in at least one line having opposing ends, this line being substantially perpendicular to a longitudinal axis of the curved platen. Preferably, the line of nozzles is arranged with its center located closest to the platen and the nozzles are actuated starting at the ends of the line of nozzles.
