The object of the current invention is to print characters, for example, on a substantially full area of a recording medium extended up to the leading or trailing edge of the recording medium. A carriage is moved so that a print hole of a ribbon mask is positioned at a medium center as viewed in the direction of feeding of a recording medium. The recording medium is fed to a position so that the print hole is at a print start position. A print operation is carried out toward a first side edge of the recording medium. The recording medium is then fed in the reverse direction to a position where the print hole is away from the recording medium as viewed in the character pitch direction. The carriage is then moved so that the print hole is positioned at a medium center as viewed in the direction of feeding of a recording medium. Thereafter, the medium is fed to a position so that the print hole is at a print start position. A print operation is then carried out toward a second side of the recording medium. A similar operation may be carried out to print on the trailing edge of a recording medium. Thus, characters may be printed on the leading or trailing edge of the recording medium without catching the any of the corners of the recording medium on the print hole.

A method of controlling a print head and a recording medium feed in a printer, the recording medium having a leading edge between first and second corners and first and second sides, comprising the steps of: moving a print head and a recording medium relatively so that the print head is positioned at a print start position located substantially midway between said first and second corners; carrying out a print operation from the print start position toward the first side of the recording medium; moving the print head and the recording medium relatively so that the print head bypasses the corner of the recording medium, and is returned to the print start position; and carrying out a print operation from the print start position toward the second side edge of the recording medium.
