Another display step displays, when the predetermined operation is received, the print information on a target area among the plurality of the outer peripheral areas such that the print information, displayed on the target area, is facing a predetermined direction based on the target area. A processing step executes a process of printing the plurality of areas displayed on the display unit and the print information facing the predetermined direction, on the print medium to be processed by folding and/or cutting off the predetermined direction.
