Abstract
A thermal printer uses a thermal line head which, when paper having a width smaller than a predetermined width is supplied in error, is able to inhibit electric supply to the heat generating devices that are situated outside of the paper to thereby prevent the heat generating devices from shortening their life span due to the idle heating thereof. There is provided a device which can be moved in the width, or lateral, direction of paper to detect the side edges of the paper and, in accordance with the moving distance of the paper side edge detection units from the reference position thereof, it is possible to specify the block of the thermal line head to which electric supply is to be inhibited.
