ABSTRACT:
The printing mechanism of a dot matrix printer includes a platen provided on its jacket with elongated ink impregnated sintered bodies each extending over the entire length of the platen. The platen is movable in the printing direction at one side of a printing paper. A printing head moves in the same direction but at a different speed at the opposite side of the paper so that impact wires strike different points on a preselected sintered body during the printing of a line.
