PRINTING APPARATUS Abstract of the Disclosure An endorsement printer for document processing systems is driven in a printing operation cycle by two separate motors. One motor, which may be of the stepping type, drives the endorsement printer in acceleration and deceleration modes before and after the actual operation of imprinting endorsement data on the document being processed. The second motor, which may be of the AC induction type, drives the endorsement printer at substantially constant velocity during the actual imprinting portion of the operation cycle. Cooperating disc and cam elements control the transmission of power from the second motor to the endorsement printer during the constant velocity portion of the cycle, during which the first motor is turned off. A data processing system re- ceives information from a document sensor and a timing disc coupled to the first motor, and controls the operation of said motor.
