ABSTRACT:
The present invention relates to a printing device having a carriage and a serial-impact printing unit carried by the carriage, wherein characters are printed on a recording medium by the printing unit after the carriage has been moved to and positioned at predetermined printing positions in a printing direction. The printing device has a judging device for checking if the printing device is placed in a precise-positioning mode which is selected when relatively high positioning accuracy of the carriage is required, or in a normal-positioning mode which is selected when there is a relatively wide range of positioning tolerance of the carriage; and a switching device, responsive to the judging device, for effecting a printing operation at a comparatively low printing speed when the judging device has judged that the printing device is placed in the precise-positioning mode, and for effecting the printing operation at a comparatively high printing speed when the judging device has judged that the printing device is placed in the normal-positioning mode.
