Abstract
An inkjet printhead includes: an array of ink ejection nozzles, an actuator for each nozzle and drive circuitry for receiving print data from a printhead controller and distributing fire signals to the actuators. The drive circuitry is configured to fire the actuators such that a first firing sequence for a first line of print is different to a second firing sequence for a subsequent second line of print.
