A thermal printer capable of performing multiple printing on a plurality of superposed recording paper sheets adapted for multiple printing. The thermal printer has a first printing mode for printing on heat-sensitive paper, a second printing mode for printing on plain paper by melting and transferring ink of an ink ribbon, and a third mode for multiple printing on multiple-printing sheets. Each of these printing modes is selected by a printing mode select switch. A control unit is provided which controls the traveling speed of a carriage and a unit time period for energizing a thermal head based on the selected printing mode.
