摘要： An embodiment of this invention is directed to preventing a decrease in the number of media printable with ink in an ink tank owing to an increase in waste ink in aging processing, and an increase in aging processing time. According to the embodiment, aging processing is executed as follows in a printing apparatus in which a printhead including a plurality of nozzles and a nozzle array formed from these nozzles and discharge ink is reciprocally scanned in a direction different from the direction of the nozzle array, and an image is printed by forward printing and backward printing. The aging processing is performed by changing the count at which the aging processing is performed, between nozzles at the edge side portion of the nozzle array and nozzles at the center side portion of the nozzle array.
