ABSTRACT:
A method and a printer are provided for printing on a thermosensitive paper by using a thermal head which has a plurality of heating dots arranged along a line extending in a primary scanning direction. The heating dots are selectively actuated according to sets of printing data for heat generation to form printing dots on the paper. The paper is fed pitch by pitch in a secondary scanning direction substantially perpendicular to the primary scanning direction. Each of the heating dots has a heating length in the primary scanning direction and an effective heating width in the secondary scanning direction, the effective heating width being smaller than the heating length.
