Abstract
A thermal printer is proposed that includes an ink ribbon on which a color ink portion and a non-color ink portion are alternately formed in a conveyance direction, a supply bobbin on which the ink ribbon is wound, a take-up bobbin on which the ink ribbon is to be wound, and a housing that contains the supply bobbin and the take-up bobbin. When an error occurs during transferring of an ink on the color ink surface, the ink ribbon is conveyed so that a portion of the ink ribbon exposed from the ink cassette between the supply bobbin and the take-up bobbin is the non-color ink portion.
