Abstract
A printing mode setting portion outputs energizing time data corresponding to a selected printing mode when selecting the printing mode according to operation of the operation unit. Based on the energizing time data, the energizing time period of a head energizing signal which is output from a head driving portion to a driving coil of a dot printer head is controlled by the energizing time control portion 6. When printing mode having a high dot density is selected, printing energy is reduced and the energizing time period is refined for the driving coil 8, thus making it made possible to lower the noise level.
