Abstract
A printing apparatus prints on a printing medium by using a printhead which has a first nozzle array including a plurality of nozzles from which a first nozzle amount of the ink is discharged and a second nozzle array including a plurality of nozzles from which a second nozzle amount of the ink is discharged. This printing apparatus time-divisionally drives a plurality of blocks obtained by dividing each of the first nozzle array and the second nozzle array. The printing apparatus selects, from the first nozzle array and the second nozzle array, a block to be driven by the driving unit within a predetermined period. This printing apparatus controls the selection unit to alternately select a block from the first nozzle array and the second nozzle array and sequentially select a block from each nozzle array in a predetermined order.
