An impact printer having a platen, an impact printing member such as a printing wire, a driver such as a driving coil for driving the impact member, a controller for controlling the driver and a temperature detector. Before printing data is printed, the temperature detector compares the temperature of the printer to a set point. If the temperature is too low, a warm-up signal is provided and the driver displaces the printing member to such an extent that printing does not occur. The warm-up signal can also cause the gap between the platen and the printing member to widen to such an extent that printing cannot occur.
