Abstract
In the present invention there is disclosed an improved serial type dot printer. According to the printer, the mutual magnetic interference between the magnetic circuits that are provided for each of the printing hammers to act as their respective driving sources, can be avoided by an appropriate choice of the distance between the printing pins, and at the same time, the power supply capacity can be reduced.
