A printhead assembly includes at least one printhead having a group of nozzles, a group of firing resisters corresponding to the group of nozzles, a programmable nozzle firing order controller configured to provide address generator control signals, and a nozzle address generator configured to respond to the address generator control signals to provide a nozzle address. The nozzle address controls a sequence of which firing resister has electrical current pass through it at a given time to thereby control a firing order of the nozzles.
