  • Printer center sensing mechanism
    Patent number: 4179223
    Abstract: Three fixed optical sensing devices are positioned to sense the left and right margins as well as the center location of high speed printer carriage travel. Signals from the sensing devices are fed to programmed carriage logic control circuits which effect rapid carriage movements relative to the center location as well as the traditional left and right margin locations. Printing time of certain forms is greatly reduced by minimizing unnecessary carriage return to the left margin location.
