Abstract
According to one embodiment, the present disclosure provides a thermal printer having a feeding motor that rotates the feeding shaft forward/backward depending on the winding configuration of the ink ribbon attached to the printer, an input part allowing the winding direction of the ink ribbon to be designated, a thermal head for transferring ink from the ribbon to a print medium, a wind-up motor that rotates the wind-up shaft of the ink ribbon after printing, a storage part for storing target rotating quantities for the wind-up motor and other target rotating quantities for the feeding motor in each winding direction, and a control part that extracts a target rotating quantity for the direction of tension for an ink-surface-outward winding ink ribbon or an ink-surface-inward winding ink ribbon and controls each motor.
