Abstract
The present invention relates to a method for driving and controlling a thermal printer. In the thermal printer provided with a carriage driving mechanism for moving a carriage including a thermal head forward and backward along a platen; a mechanism for moving upward and downward the thermal head to bring it into contact with and detach it from said platen; and a sheet forwarding mechanism for forwarding a print sheet in the direction perpendicular to the sheet forwarding direction; the time required for the printing operation by the printer is shortened as a whole and thus it is possible to raise the effective printing speed by controlling the drive of the printer so that the upward movement and/or the downward movement of the thermal head and the moving operation of the carriage or the sheet forwarding operation are effected, overlapped with each other.
