ABSTRACT:
An ink-jet printer includes a printhead disposed on a reciprocating carriage. The printhead includes two sets of ejectors spaced by a predetermined pitch, in collinear linear arrays. The two sets of ejectors are offset by a partial pitch to enable interleaving of print swaths by the two sets of ejectors, in order to print at a higher resolution than the predetermined pitch would allow.
