摘要： The temperature of the printing elements in a thermal printing head is controlled by controlling the electrical power supply to the thermal head, and thereby the amount of heat that is generated, said control also taking account of the different printing requirements of ordinary characters, bar codes, and so forth, data on the various such types of printing being stored in electronic memories for reference thereto for the said temperature control. The result is printing that is sharper and more uniform.
