The printing device includes a housing (6,7) body which can effect a translational movement relative to a printing surface in use, in a plurality of wire elements (needles) (8) slidable in the housing body each having one end (10) for acting on the printing surface as a result of a thrust exerted on the other end (13), and a plurality of oscillating operating members (25) each of which can exert a thrust on a respective wire element (8). Electromagnetic excitation circuits (16) selectively oscillate each of the operating members (25) from a rest position to a position of thrusting the respective wire element (8). The oscillating operating members are fixed to a single resilient support element (26). The position of fixing each operating member (25) to the support element (26) and the resilient properties of the support element (26) itself determine, respectively, the path of oscillation of the operating member (25) and the degree of resilient force which returns the member (26) to the rest position.
