ABSTRACT:
An integrally-formed print element for providing finer dots than previously possible with an impact printer. The dots produced permit the printing of Chinese, Amharic, Devanagari, and like characters, in sizes as small as standard newsprint, and print in books and periodicals, without significant distortion of the characters. The print element has an axis of symmetry and includes in order a cylindrical base with a longitudinal axis corresponding to the axis of symmetry of the print element; a frusto-conical-shaped impact element support with its largest diameter end extending from one end of the cylindrical base; and a cylindrical impact element located on and extending integrally from the other end of the frusto-conical-shaped support. The overall size of the print element is preferably such that it is attachable to standard impact printer hammer tips.
