A printing apparatus includes: a conveyor; an image recording device configured to record an image on a printing medium conveyed in a conveyance direction by the conveyor; a divider provided downstream of the image recording device in the conveyance direction and configured to divide the printing medium; a detector provided upstream of the divider in the conveyance direction and configured to detect a trailing end portion of the printing medium; and a controller causing the printing apparatus to: calculate a dividing position of the printing medium based on a length of the printing medium that is grasped by detecting the trailing end portion by the detector; convey the printing medium in a reverse direction by the conveyor to move the dividing position to a position of the divider; and divide the printing medium at the dividing position by the divider.
