Abstract
Included are a first roller disposed upstream of a peeling unit, a second roller disposed downstream of the peeling unit, a first motor configured to drive the first roller, a second motor configured to drive the second roller, and a control unit. The control unit includes a first-motor control unit configured to adjust a first voltage applied to the first motor on the basis of information about a transport velocity and a transport acceleration of the label sheet, such that a load torque of the first motor is a target torque, and also includes a second-motor control unit configured to perform feedback control of a second voltage applied to the second motor on the basis of information about a transport velocity of a base sheet, such that the transport velocity of the base sheet is a target transport velocity.
