ABSTRACT:
A row of thick-film resistors connected by thick-film conductors on a ceramic substrate are suitably powered to form a thermal printing head. Thermally-sensitive paper is placed in intimate contact with the resistors, some of which are heated to a temperature sufficient to cause a color change in the paper to thereby produce a corresponding array of dots. The paper is moved across the printing head in incremental steps, forming other arrays of dots. The dots combine to form alphanumeric characters.
