Abstract
An object of the present invention is to efficiently perform a reading operation for printing position adjustment with high accuracy. A printing apparatus prints, on a print medium, adjustment patterns for adjusting a printing position on the print medium and corresponding respectively to printing position adjustment items. In this printing, the printing apparatus prints the adjustment patterns while conveying the print medium in a forward direction with a conveying unit. Then, the conveying unit conveys the print medium in a backward direction until the adjustment patterns are moved beyond a reading position of a reading unit in the backward direction. Thereafter, the conveying unit conveys the print medium in the forward direction again to cause the adjustment patterns to reach the reading position. Thereafter, the reading unit reads the adjustment patterns continuously at the reading position while the conveying unit conveys the print medium in the forward direction.
