ABSTRACT:
A printhead is provided for an inkjet printer. The printhead includes a wafer substrate assembly defining rows of evenly spaced ink inlet channels. Rows of ink ejection nozzle arrangements extend from the wafer substrate assembly and are in fluid communication with respective ink inlet channel rows. Each nozzle arrangement defines an ink ejection port from which ink can be ejected. Adjacent rows of ink ejection nozzle arrangements are axially offset relative to each other so that the resulting two dimensional array of ink ejection ports is a non-orthogonal grid.
