Abstract

PURPOSE:To prevent overlapped dotting in the dots of thermal printing and thereby provide beautiful printing by changing the size of heat generating zone of a thermal printing elements in accordance with the line density in the direction of sub-scanning. CONSTITUTION:In a heat-sensitive recording device which is provided with a plurality of thermal printing elements 11 and is capable of changing the feed (sub-scanning) of paper in the manners such as normal driving, high speed driving, driving with high resolution, and capable of changing line density, the device is provided with a device to change the value of voltage and the pulse width of electric current applied to the thermal printing element 11 in accordance with the speed of the paper feeding. For example, when low paper feed speed is taken to make printing of high resolution, the voltage of the current applied to the thermal printing elements is made low or the width of the current pulse small to make the printed dots small, which prevents overlapping of dots and make it possible to print beautiful letters.
