Printing apparatus with device in transport path

A method of controlling a printing apparatus, the printing apparatus including:

• a transport roller configured to transport a medium through a transport path;
• a printing unit configured to perform printing on the medium transported by the transport roller;
• an intermediate roller configured to transport again, to the transport path, the medium transported through an inversion path in a reverse direction to a transport direction of the medium to invert a front surface and a back surface of the medium, the inversion path including a branching point at which the inversion path branches from the transport path upstream of the transport roller in the transport direction, the inversion path merging with the transport path again upstream of the branching point in the transport direction;
• an imaging device disposed in the transport path and between the transport roller and the intermediate roller;
• a first driving device configured to drive the transport roller;
• and
• a second driving device configured to drive the intermediate roller, the method including:
• rotating the transport roller and the intermediate roller in a forward direction to transport the medium in the transport direction when printing is performed on the medium by the printing unit;
• rotating the transport roller in a reverse direction that is a direction opposite to the forward direction and rotating the intermediate roller in the forward direction when the front surface and the back surface of the medium on which printing is performed by the printing unit is inverted;
• and
• rotating the intermediate roller in the reverse direction to transport the medium in the reverse direction when the imaging device captures an image printed on the medium by the printing unit.

• when the medium is cut by the cutter, rotating the intermediate roller in the reverse direction to transport the medium in the reverse direction.
