Abstract: The printing apparatus includes a transport unit, a printing unit, a support portion, and a suction force applying unit. The transport unit is configured to apply a transport force to the printing medium and transport the printing medium. The printing unit is configured to perform printing on the printing medium transported. The support portion includes a support face configured to support the printing medium at a position upstream of the transport unit in a transport direction in which the transport unit transports the printing medium. The suction force applying unit is configured to apply, to the printing medium transported along the support face, a suction force attracting the printing medium to the support face, thereby generating a surface pressure based on the suction force between the printing medium and the support face.
