1. A printing apparatus comprising:
a printing head configured to perform printing on a label sheet obtained by attaching a label to a base sheet;
a peeling unit configured to peel the label from the base sheet;
a first roller disposed upstream of the peeling unit in a transport path of the label sheet;
a second roller disposed downstream of the peeling unit in a transport path of the base sheet;
a first driving unit configured to drive the first roller;
a second driving unit configured to drive the second roller; and
a control unit configured to control the first driving unit and the second driving unit, wherein
the control unit adjusts a voltage applied to the first driving unit on a basis of information about a transport velocity and a transport acceleration of the label sheet, such that a load torque of the first driving unit is a predetermined value, and
the control unit performs feedback control of a voltage applied to the second driving unit on a basis of information about a transport velocity of the base sheet, such that the transport velocity of the base sheet is a predetermined velocity.
