したことを特徴とするプリンタ装置。 A platen roller, a thermal head provided for the platen roller, a plunger for pressing the thermal head against the platen roller, a pulse generating means for generating pulses in response to rotation of the platen roller, and A count means for counting the pulses generated by the pulse generation means, and a control means for controlling the electric power supplied to the plunger based on the output signal of the count means, and the control means controls the output power of the thermal head. At the start of the crimping operation to the platen roller, power is supplied to the plunger so that the crimping driving force of the thermal head by the plunger becomes large, and then the power supplied to the plunger is controlled so that the crimping driving force becomes small. The printer apparatus is further characterized in that, after the thermal head finishes pressing against the platen roller, the electric power supplied to the plunger is controlled so that the driving force for this pressing becomes large.
