ABSTRACT:
The present invention is directed to a hammer actuated printer comprising a printing drum, a plurality of type carrying belts secured around the printing drum, and a plurality of hammers for depressing a paper toward a selected type carried on the type carrying belts. A plurality of separator strips are formed on the printing drum surface for separating the type carrying belts from each other. The separator strips have a height higher than that of the types carried by the type carrying belts, thereby precluding the paper from coming in contact with types which are not selected.
