Abstract
A printhead has a substrate with a first surface, an opposite substantially parallel second surface, and an edge surface extending from the first surface to the second surface. The substrate further includes a fluid channel that extends from the edge surface inward away from the edge surface and through a recess in the first surface. The printhead further has a heating element disposed over the first surface, and a firing chamber disposed over the heating element. The fluid channel directs fluid to the firing chamber through the recess, where the fluid is heated by the heating element and ejected therefrom.
