A printing apparatus includes an acquiring unit to acquire information on a shape of a label, a printing unit to perform printing on the label, a conveying unit to convey the print medium, and a detecting unit to detect the label. In addition, the detecting unit is movable in a direction intersecting a width direction of the sheet, and a control unit, when the label has a shape including a portion protruding towards a downstream side in a conveyance direction, moves the detecting unit to a region corresponding to a most protruding position of the label on the downstream side in the conveyance direction and stops the detecting unit in the region on the basis of the acquired information, and starts the printing unit to start the printing on the label on the basis of a detection result of the detecting unit that is located in the region.
