1. A printhead assembly, comprising:
a printbar beam member having a printbar longitudinal axis; a plurality of printheads in which each printhead includes a printhead longitudinal axis and a row of nozzles arranged parallel to the printhead longitudinal axis, the plurality of printheads are arranged on the printbar beam member in a manner in which each respective printhead longitudinal axis is traverse to the printbar longitudinal axis and a portion of respective rows of the nozzles of adjacent printheads overlap each other with respect to the printbar longitudinal axis; and wherein nozzles of the adjacent printheads are not arranged along a same line perpendicular to the printbar longitudinal axis; and wherein an effective distance between nozzles of a row with respect to the printbar longitudinal axis is half the distance of nozzles of a row of a printhead having a printhead longitudinal axis parallel to the printbar longitudinal axis.
