Abstract
A piezoelectric ink jet printing system including a primary ink supply and a plurality of piezoelectric ink jet printhead assemblies. Each assembly comprises a housing, a piezoelectric ink jet printhead in the housing, a secondary ink supply attached to the housing adjacent the printhead, and an ink supply line for delivery of ink from the secondary ink supply to the printhead. The system further includes a pump for pumping ink from the primary ink supply to the secondary ink supply of each printhead assembly. Each printhead assembly is operable independently of the other printhead assemblies and are selectively movable with respect to the other printhead assemblies and with respect to the primary ink supply so that each printhead assembly can be positioned at a desired location without regard to where the other printhead assemblies are to be positioned and without regard to where the primary ink supply is positioned.
