    摘要: A printing apparatus comprises a type wheel carrying a plurality of type elements and a platen for mounting and advancing a printing paper. A hammer can strike any one of the type elements against the printing paper and an ink ribbon is positionable between the type elements and the paper to imprint a character on the paper when any one of the type elements is struck. The ink ribbon is advanced by a driving mechanism. First, second, and third selecting systems respectively select one of a plurality of degrees of advancement of the printing paper, one of a plurality of time intervals of actuation of the hammer, and one of a plurality of amounts of advancement of the ink ribbon. First, second, and third counters each count pulses from respectively associated first, second, and third pulse generators to, respectively, first, second, and third set values determined by the selected degree of paper advancement, time interval of hammer actuation, and amount of ribbon advancement. First, second, and third control circuits respectively start paper advance, hammer actuation and ribbon advance upon selection by the corresponding selecting systems and stop such paper advance, hammer actuation and ribbon advance when the corresponding counter counts to its set value. The three control circuits are operated in a coordinated manner by a microprocessor.
