ABSTRACT:
A dot-matrix line printer includes a printing shuttle which moves reciprocally to carry out a printing operation, and a balancing shuttle which moves in a direction opposite to the direction of the movement of the printing shuttle. The balancing shuttle is partly inserted in the printing shuttle so as not to interfere with the latter upon printing and so that the center of gravity of the balancing shuttle is located as close to the center of gravity of the printing shuttle as possible.
