Abstract
An inkjet printing apparatus, having a carriage incorporating an inkjet printhead where nozzles for discharging ink are arranged in a predetermined direction, performs printing by scanning the carriage with respect to a printing medium in a direction orthogonal to the nozzle arrangement direction. The apparatus includes first and second conveyance sections, which are arranged at the front and rear of the area scanned by the printhead, for holding and conveying the printing medium. When the printing medium is held only by one of the conveyance sections, nozzles to be used for printing are selected from the nozzles satisfying the condition that the distance between a discharge surface of the nozzle and a printing surface of the printing medium falls within a predetermined range, in accordance with a position of the printing medium with respect to the printing-medium conveyance direction.
