A printing head 1 is driven by an output from an output port O1, a printing head moving motor 2 is rotated by an output from an output port O2, and a line feed motor 3 is rotated by an output from an output port O3. With the detection of a line feed code in the input data, continuous line feed codes are all added and, thereafter, the total line feed amount is compared with a predetermined value. If the line feed amount is judged to be larger in the comparison, a printing head is firstly moved to the center of a platen and, thereafter, a line feed action is started. On the other hand, the line feed amount is judged to be smaller in the comparison, a line feed action is immediately started.
