Abstract
A fluid-ejection printhead includes a sparse array of fluid-ejection nozzles through which fluid is ejected onto dot rows parallel to a scan axis of the fluid ejection printhead. The fluid is ejected by more than one fluid-ejection nozzle of the sparse array onto each dot row. The fluid-ejection printhead includes fluid ejection element. Each element can correspond to a pair of the fluid-ejection nozzles through which the fluid is ejected onto a same dot row and include a corresponding pair of fluid-ejection actuators. Each element can instead correspond to one of the fluid-ejection nozzles and include one fluid-ejection actuator.
