Abstract
A thermal printing head for multi-tone reproduction includes a plurality of heating resistors disposed along the scanning line which differ in the magnitude of thermal output upon energization thereof by the same electric current for an identical time period. This effect is achieved by differing the heating area or by differing resistivity of each heating resistors. Selective energization of none, one or more of the heating surfaces enables the reproduction of different tones or colors on the thermo sensitive paper.
