Provided are a thermal head printing method and device carrying out printing on a place to be printed of a moving object by a thermal head arranged not to move in a moving direction of the printing object. In the thermal head printing device carrying out printing on the place to be printed of a packaging film ( 10 ) as the moving object supplied between a thermal head ( 8 ), arranged not to move in the moving direction of the moving object, and a platen ( 9 ), the printing device comprises moving rolls ( 15, 16 ) arranged on both sides of the platen ( 9 ) to change a stagnation quantity of the packaging film ( 10 ) on a side of the platen ( 9 ). The printing is carried out by the moving rolls ( 15, 16 ) being displaced to change a moving velocity of the place to be printed. The place to be printed of the packaging film ( 10 ) is moved at a predetermined velocity held within a velocity range within which a clear printing can be carried out by the thermal head. Thereby, even on the place to be printed of the packaging film ( 10 ) moving at a velocity higher than, or lower than, the predetermined velocity, a clear printing can be carried out.
