PURPOSE:To improve the precision of line feed by providing a switch means for adding a minute quantity to or subtracting the same from a line feed value stored in a memory, and another memory storing the line feed value subjected to addition or subtraction, and by determining the quantity of line feed on the basis of a value of the other memory. CONSTITUTION:The quantity of fine adjustment of line feed is set. Test printing for setting the quantity of fine adjustment of line feed is started, and MPU 5 reads a set value of DIP SW 6 and adds an offset value corresponding to the read set value to a line feed value of a memory 7a. The value thus obtained is stored in a memory 7b, an appropriate pattern is recorded in one line, a pulse motor 9 is driven by the value (number of pulses) of the memory 7b to execute line feed, and recording is conducted another line. In the case when overlap, blank or the like is found in a joint of the recorded pattern due to the line feed, the operation conducted thereto fore is repeated, and when the overlap or the like is not found, the fine adjustment of the quantity of line feed ends.
