Abstract
A label printer for a bar code comprising a heat printing head having resistance dots for printing the bar code on a heat sensitive label. A motor feeds the label with a constant speed, e.g. 10 cm/sec. The printing head receives electrical power pulses form a control unit which receives signals from a memory unit and a CPU-unit. The CPU-unit receives external signals form e.g. a weighing machine, a keyboard or an external computer and computes the bar code, check figures or the like. The printing head comprises a substrate including the electronic circuits and the resistance dots. The substrate is supported by a metal block which comprises temperature sensors which control the power pulses to the resistance dots.
