A number of printhead chips ( 186 ) are positioned on the carrier ( 187 ), the printhead chips ( 186 ) together incorporating at least fifty thousand nozzle arrangements ( 210 ). The printhead chips ( 186 ) are positioned so that the printhead chips ( 186 ) are capable of ejecting ink drops into a printing zone ( 120 ) defined by the platen ( 106 ). Control circuitry ( 190 ) is also positioned on the carrier ( 187 ) and is configured to control operation of the printhead chips ( 186 ).
