摘要： A printing apparatus prints on a printing medium by scanning a printhead having a plurality of nozzle arrays in a first direction and a second direction opposite to the first direction, and has a structure in which an air flow entering the nozzle array in the scan of the printhead in the first direction becomes larger than an air flow entering the nozzle array in the scan of the printhead in the second direction. The apparatus increases, in scanning in the second direction, discharge speed of ink discharged from at least one nozzle array arranged leeward in the scanning direction of the printhead from a predetermined position on the printhead in the scanning direction to be higher than or equal to the discharge speed of ink discharged from at least one nozzle array arranged windward in the scanning direction of the printhead from the predetermined position.
