ABSTRACT:
A method of dot-printing underline or the like employing a print head and power source with relatively small capacity. The reciprocation of the print head is divided into a plurality of travels by the command of divisional print so that the required underline print is performed by the collected dot prints being printed at intervals on each of a plurality of travels of the print head. A rest time will be provided between each printing actions at intervals of the print head to reduce the capacity of a power source employed for driving the dot pins in the print head.
