ABSTRACT:
A printhead assembly is provided having at least one printhead module, a support frame removably supporting the printhead module and at least one mounting element; and drive electronics removably mounted to the mounting element to control operation of the print nozzle integrated circuits. Each printhead module has at least two print nozzle integrated circuits, a support member supporting, and carrying printing fluid for, the nozzle ICs, and an electrical connector for connecting electrical signals to the nozzle ICs. The drive electronics has contacts for electrical connection to the electrical connector, input contacts for receiving print data, and a controller for processing the print data applicable to a predetermined number of the print nozzle ICs. The drive electronics is selected from a range of drive electronics, each having a different number of controllers such that the ratio of controllers to nozzle ICs can be varied to change the print speed.
