ABSTRACT:
A printhead having a plurality of drop generators formed on a substrate. Each drop generator includes a nozzle, and the nozzles are arranged in a dual inline architecture. In one embodiment, a column of nozzles includes a first group of nozzles located at a first axial position relative to a scan axis and a second group of nozzles located at a second axial position relative to the scan axis so that all nozzles in the column are located at either the first axial position or the second axial position. The distance along the scan axis between the first axial position and the second axial position is set to reduce dot placement error.
