Abstract: A printing apparatus includes a feeding unit, a pair of rollers, a printing unit, and a control unit. The control unit can execute skew correction. The control unit can execute control to convey a preceding printing medium and a succeeding printing medium by the pair of rollers in a state in which a trailing edge portion of the preceding printing medium and a leading edge portion of the succeeding printing medium overlap. The control unit sets an execution timing of the skew correction for the succeeding printing medium based on positions of the preceding printing medium and the succeeding printing medium if a predetermined condition is met. The predetermined condition is that the preceding printing medium reaches a position at which a remaining print range for the preceding printing medium equals a predetermined print range.
