1. A printing apparatus comprising:
a supply unit configured to supply a print medium;
a first roller configured to transport the print medium, supplied by the supply unit, in a transport direction;
a printing unit configured to print on the print medium transported by the first roller;
a second roller disposed downstream from the printing unit and configured to transport the print medium transported by the first roller; and
a control unit capable of controlling the supply unit and the first roller to create a state of overlap in which a leading end part of a following print medium overlaps a following end part of a preceding print medium on an upstream side of the first roller with respect to the transport direction of the print medium,
wherein the control unit changes an overlap amount in the state of overlap on the upstream side of the first roller with respect to the transport direction of the print medium based on print data for the preceding print medium and print data for the following print medium, and after changing the overlap amount, the preceding print medium and the following print medium are separated between the first roller and the second roller.
