A printing apparatus includes a transport unit configured to transport a medium, a winding unit disposed downstream, in a transport direction, of the transport unit, the winding unit being configured to wind the medium, and a tension applying unit including a rod member biased toward the medium between the transport unit and the winding unit, the rod member being for applying a tension to the medium. The tension applying unit is configured so that the rod member moves along a predetermined direction as at least one of the transport unit and the winding unit is driven to transport the medium. An upper limit position of a movement of the tension bar along the predetermined axis is changed according to a winding mode of the winding unit.

A medium wind-up apparatus includes a reel-out motor, which is a driving source that winds up a medium, a control portion that controls the reel-out motor on the basis of a torque limit value, which regulates an upper limit of an output torque of the reel-out motor, and a reel-out side detection portion that detects a rotation speed of the reel-out motor, in which the control portion changes the torque limit value on the basis of the detected rotation speed. In this case, it is preferable that the control portion increase the torque limit value in a case in which the detected rotation speed falls below a first threshold value, and that the control portion reduce the torque limit value in a case in which the detected rotation speed exceeds a second threshold value, which is larger than the first threshold value.
