ABSTRACT:
A printhead assembly includes a printhead. The printhead includes a carrier which carries an integrated circuit (IC) configured to eject ink. The carrier defines a plurality of ink passages each in fluid communication with the IC. An elongate support supports the printhead and defines a plurality of ink chambers each in fluid communication with a respective ink passage. The support includes a core which defines the ink chambers and a multi-layered metal shell in which the core is received.
