Abstract
A printing device reduces the load on the reel driver that drives a delivery reel. A controller drives a reel driver to turn at multiple drive speeds, including a minimum speed at which the circumferential speed of a media roll of the largest diameter is equal to, and a maximum speed at which the circumferential speed of a media roll of the smallest diameter is equal to, the conveyance speed of the media conveyor. When the amount of slack detected by a slack detector goes from between a first threshold and a second threshold that is less than the first threshold, to an amount of slack less than the first threshold, the controller changes the drive speed to one higher speed if the reel driver is not turning at the maximum speed, and stops the reel driver if the reel driver is turning at the maximum speed.
