ABSTRACT:
A printing apparatus uses a printhead, which has a first nozzle array and a second nozzle array, each having a plurality of nozzles with a first nozzle discharging a first amount of ink and a second nozzle away having a plurality of nozzles with a second nozzle discharging a second amount of the ink and including nozzles to be used for printing on a printing medium and nozzles not to be used for printing on the printing medium. The printing apparatus selects, from the first nozzle array and the second nozzle array, nozzles to be driven within a predetermined period. The printing apparatus controls preliminary discharge control to drive the nozzles to be used for printing and the nozzles not to be used for printing by alternatively selecting the first nozzles and the second nozzles.
