Abstract
A thermal transfer printer includes a head holding member for holding a printing head and for applying an urging force for urging the printing head against a platen and separating the printing head from the platen. An elastic member biases the head holding member to urge the printing head against the platen. A regulating member regulates displacement of the elastic member to change the urging force of the printing head against the platen. A driving unit drives the regulating member. A detecting unit detects either one or both of the type of ink ribbon or the surface roughness of recording paper. A control unit controls the driving unit in accordance with the result of the detecting unit. The urging force of the printing head is thus changed in accordance with either one or both of the type of ink ribbon or the surface roughness of the recording paper.
