a medium transport mechanism configured to transport a printing medium;

a printing head configured to perform printing on the printing medium transported by the medium transport mechanism;

a medium supply mechanism configured to supply the printing medium toward the medium transport mechanism;

a movable member positioned between the medium transport mechanism and the medium supply mechanism on a transport path of the printing medium, the movable member being configured to move following a change in length of the printing medium between the medium transport mechanism and the medium supply mechanism;

a first detector configured to detect whether a moving amount of the movable member becomes equal to or more than a first threshold;

a second detector configured to detect whether the moving amount of the movable member becomes equal to or more than a second threshold that is larger than the first threshold; and

a control unit configured to control driving of the medium supply mechanism based on a detection result of the first detector or a detection result of the second detector, wherein

the medium transport mechanism has, as a drive mode, a first mode in which the printing medium is transported at a first transport speed, and a second mode in which the printing medium is transported at a second transport speed that is slower than the first transport speed, and

the control unit is configured to control the driving of the medium supply mechanism based on the detection result of the first detector when the medium transport mechanism is driven in the first mode, and is configured to control the driving of the medium supply mechanism based on the detection result of the second detector when the medium transport mechanism is driven in the second mode.
