ABSTRACT:
A print control mechanism for a dot matrix printer for effecting normal printing speed relative to response time of the print elements. The mechanism includes a memory for storing the status of a previous printing operation by one print element prior to a subsequent printing operation by the same print element. The mechanism includes print inhibiting means coupled to the memory and adapted to compare a print command signal with a memory signal and to output a signal forbidding the subsequent printing operation by the same print element when it receives a print command signal following the previous printing operation. The effect of this mechanism is to inhibit continuous printing of dots in very dot position in the lateral direction for those characters which can be printed with dots in every other dot position to enable normal printing speed.
