ABSTRACT:
A printer mechanism is provided for adjusting the position of hammers when the relative distance between a type character and a print hammer is changed. The mechanism comprises a plurality of hammers driven toward a series of type characters which are continuously carried along the printing line to print characters on a record sheet interposed between said print hammers and type characters. The mechanism is designed such that said print hammers are shifted in the printing line so that the positions of respective hammers may be adjusted and correct printing is accomplished.
