Abstract

Print impression control mechanism for regulating the impact velocity of a single element printing head against a platen. The printing head is normally retained to a rest position which is in a fixedly spaced relationship to the platen independent of manual adjustment of an impression control lever so as to provide best visibility of printed characters on the record medium. In a first part of each print cycle, the head is brought to an intermediate position from which it is accelerated to get sufficient velocity for printing in a subsequent second part of the print cycle. Such an intermediate position is determined depending upon manual adjustment of the control lever whereby the impression of the printed characters can be determined accordingly.
