Preferably, the printing mode is selectable between a high resolution one and an ordinary one such that in the high resolution mode, the printing head is driven in the backward travelling of the printing hammer, dots are formed between dot rows formed in the forward travelling of the printing hammer so that printing is performed over one line through one reciprocating traveling of the printing head, and in the ordinary mode, the printing hammer is driven to perform printing over one line and a new line making through each of the forward and backward travelling of the printing head.
