Abstract
A printer includes a supply-side roll, a winding roller, a detector, a printing assembly, a conveying roller, and an adjuster. The supply-side roll is formed by winding an ink ribbon around a delivery roller. The winding roller winds the ink ribbon. The detector detects a change in tension of the ink ribbon. The printing assembly prints on a printing medium via the ink ribbon stretched between the supply-side roll and a collection-side roll formed by winding the ink ribbon. The conveying roller winds the ink ribbon and rotates in a direction in which the ink ribbon is wound by the winding roller. The adjuster adjusts, based on the change in the tension of the ink ribbon, a frictional force applied between the conveying roller and the ink ribbon and keeps constant tension of the ink ribbon passing through the printing assembly.
