ABSTRACT:
An ink jet printer for printing a print image on a moving print medium by selectively depositing ink drops at a plurality of print positions arranged in a non-uniform rectangular grid on the medium, such that a plurality of print lines are formed on the medium, includes a print head for generating a plurality of jet drop streams directed at the medium, and arranged in a row which is skewed with respect to the direction of movement of the medium. The drops in each stream are selectively charged and deflected in a direction perpendicular to the row. Each stream services a plurality of print positions and prints a band of print lines. Drops deposited along adjacent print lines by adjacent jets overlap more than drops deposited along adjacent print lines by the same jet.
