Assistance features for loading a medium into a printing apparatus

A printing apparatus comprising:

• a transport unit that transports a medium that is nipped by a roller pair in a transport direction;
• a printing unit that prints on the medium at a position downstream of the roller pair in the transport direction;
• a detection unit that detects the medium at a position downstream of the roller pair in the transport direction using either the medium or a mark applied to the medium as a detection target;
• a drive unit that is capable of driving the roller pair to a non-nipping state in which there is a gap open in the roller pair and the roller pair is not capable of nipping the medium and to a nipping state in which the roller pair is capable of nipping the medium;
• and
• a controller that controls at least the transport unit and the drive unit so as to perform an assistance operation to assist setting of the medium in the transport unit, wherein
• the controller performs the assistance operation, wherein the assistance operation includes:
• a nipping operation in which, from the non-nipping state of the roller pair, the detection unit detects the medium and the roller pair is driven to the nipping state to cause the medium to be nipped by the roller pair, and
• a skew correction operation following on from the nipping operation in which rotation of the roller pair is controlled such that the medium is transported downstream in the transport direction and such that the medium is transported upstream in the transport direction.
