Method of controlling a carriage and a paper feed in a printer.

摘要

The object of the current invention is to print characters, for example, on a substantially full area of a recording medium (30) extended up to the leading (32) or trailing (34) edge of the recording medium. A carriage (10) is moved so that a print hole (15) of a ribbon mask (14) 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 any of the corners of the recording medium on the print hole. <IMAGE>
