Abstract: A printer, which is especially adapted for printing a bar code on label paper has a housing having a front panel with some operation buttons and a winding drawer having a protruding label table. The printer prints a bar code and alphanumeric numerals on a label which is fed to the label table for then being applied to goods. The printer also can be connected to an external computer or the like for obtaining the information to be printed on the label. The printer also has an internal processor and a memory for maintaining certain necessary information. The winding drawer has a winding roller and a deflection roller on a pivotable operation lever. The deflection roller deflects ground paper of the label paper over a dispenser edge in a first position of the operation lever, so that a label formerly on the ground paper is delivered straight ahead while the ground paper is deflected downwards to the winding roller operation.

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.
