A printing apparatus and a printing control method are disclosed, which can ensure a sufficient acceleration area for stable movement of a carriage and realize the downsizing. According to the printing apparatus, an inkjet printhead is used, on which a plurality of nozzle arrays each having a plurality of nozzles for discharging ink are arranged in a direction different from the array direction of the nozzles. The apparatus performs printing operation on a printing medium by discharging ink while reciprocally moving the carriage, on which the above inkjet printhead is mounted, in a direction in which the plurality of nozzle arrays are arranged. When preliminary discharge is performed from the inkjet printhead to an ink receptor arranged on at least one end of a reciprocal movement area of the inkjet printhead, the carriage is stopped. The scanning of the carriage is controlled so that the carriage accelerates from zero speed to a predetermined speed after the preliminary discharge is completed, and moves at the predetermined speed. On the other hand, the movement of the carriage and preliminary discharge are so controlled as to sequentially perform preliminary discharge with regard to the plurality of nozzle arrays from one nozzle array arranged outside the reciprocal movement area to another nozzle array arranged inside the area.
