Transport device and printing apparatus

A printing apparatus, comprising:

• a transport belt having an adhesive layer to which a medium is adherable and being configured to transport the medium adhering to the adhesive layer;
• a printing unit configured to perform printing on the medium transported by the transport belt;
• an abutting unit configured to abut against a surface of the adhesive layer;
• a moving mechanism configured to move a position of the abutting unit with respect to the surface in a first direction and a second direction, the first direction being a direction in which the abutting unit is away from the adhesive layer, the second direction being a direction opposite to the first direction and a direction in which the abutting unit approaches the adhesive layer;
• and
• a displacement detection unit configured to detect a displacement amount of the transport belt in the first direction, when the moving mechanism moves the abutting unit in the first direction while the abutting unit abuts against the surface.
