  • Thermal matrix type printing head
    Patent number: 4023184
    Abstract: A printer for recording images on thermally sensitive paper. It includes a head that comprises a set of longitudinally extending fingers comprising laminated highly conductive and resistive heating layers. Gaps in the electrically conductive layers traverse the fingers to form discrete printing areas in the resistive layers. An electrical current selectively passed through a finger heats the printing area therein and thereby records a dot image at a corresponding portion of the paper.
