Abstract
A battery powered serial printer having a print head for printing data on a printing sheet in a normal direction from the beginning of a line or in the reverse direction from the end of a line includes a drive unit for moving the print head in reciprocatory movement in the normal and reverse directions, and a device for judging whether the print head is printing characters in the normal direction or in the reverse direction. The serial printer further includes a correcting device responsive to voltage changes for delaying the initiation of the operation of printing characters by the print head at the least in either the normal direction and/or the reverse direction judged by the judging device, so as to bring the positions of characters printed in the normal direction into alignment with the positions of characters printed in the reverse direction.
