ABSTRACT:
A page width printhead assembly (1) for a digital inkjet printer has a support member that can be secured in the printer, and a printhead (2) that can be mounted to the support member. The support member has a core with at least one ink reservoir (6, 7, 8and9) enclosed within a laminated shell (4). The materials and structure of the shell (4) and the core (5) are selected and configured so that the co-efficient of thermal expansion of the support member as a whole is substantially equal to that of the printhead (2).
