This article describes a thermal printing system utilizing a resistive ribbon in which highly localized heating is obtained by means of passing current into the ribbon via contacting electrodes. The intense local heating triggers the thermally sensitive printing reaction and results in a printed mark on the paper. Since the print head does not get hot as in known thermal printers, there is not a waiting time for the print head to cool, and, accordingly, higher printing speeds are achieved. Higher resolution is obtainable, since there is localized heating in the ribbon instead of the area resistor as used in known thermal printers.
