Abstract

PURPOSE:To perform high speed printing without raising a thermal head to a hgih temperature, and to prolong the life of resistors, by repeating charging resistors in turn twice or more that should heat during one printing process. CONSTITUTION:There are n groups of resistors 2, each group comprising m resistors, and terminals 1G, 2G...nG and terminals S1, S2...Sn are led from respective groups. The terminal 1G and a contact Si that is connected to a resistor 2 in the same group and corresponding to a dot to be printed are connected to an electric source, the terminal 2G and a contact Si that is connected to a resistor 2 in the same group and corresponding to a dot to be printed are connected to an electric source, and so on, so that an electric current is passed to the resistors in accordance with the printing position on a heat-sensitive paper 1. One heating period in each group is perdetermined such that the heat-sensitive paper 1 is completely subjected to heat-sensitive reaction by repeating the heating several times, so that for the same line the heating operation is repeated without moving the heat-sensitive paper.
