Abstract
A printhead for an inkjet printer includes a wafer assembly defining rows of spaced apart ink supply channels; and rows of ink ejection nozzle groups extending from the wafer assembly, each nozzle group including a pair of rows of ink ejection nozzles, each ink ejection nozzle including an ink ejection head from which an elongate actuator tail extends, all of the ink ejection heads of each group being in fluid communication with a respective ink supply channel. In each nozzle group, the actuator tails of one pair of rows of ink ejection nozzles extend in an opposite direction to the actuator tails of the other pair of rows of ink ejection nozzles. The actuator tails from adjacent rows of ink ejection nozzle groups are interleaved.
