PRINTHEAD IN WHICH INTER-GROUP SPACING IS GREATER THAN INTRA-GROUP SPACING

摘要

A fluid-ejection printhead includes channel, interposer, and fluid- ejection layers. The channel layer has supply and return channels. The interposer layer defines inlet and outlet ports respectively fluidically connected to the supply and return channels. The fluid-ejection layer includes fluid- ejection element groups that each include first and second fluid-ejection elements fluidically connected to the supply and return channels. The inter-group spacing along an axis non-perpendicular to a channel axis of the supply and return channels is greater than the intra-group spacing along the axis.
