ABSTRACT:
A printer is fitted with a squeeze printing mechanism employing a toggle or over-the-center crank mechanism to provide direct pressure to a printing element for accurate impression depth control during imprinting and for achieving low velocity at the time of print element contact with the paper to materially reduce printing noise. Mechanism and linkages are provided for either single or double electromagnetic actuators. The linkages are arranged to provide rectilinear movement of the type face bearing element just prior to and during imprinting. Over pressure relief is provided for the toggle or over-the-center crank mechanism to prevent damage or lock-up if the printer platen position is not correctly adjusted for the paper being used.
