The inventor discloses a hammer assembly suited for use in generating impact for printers, such as printers using daisy-wheels. The assembly comprises an electromagnetic assembly for selectively producing an electromagnetic field across an air gap. A hammer element is slidably disposed in said gap so that it is biased in a rest position and moves toward another position when said field is activated. A damping assembly is provided to dampen the reciprocating movement of the hammer element. The damping assembly has a rigid element which collides with the hammer element to bring it to a stop at its rest position. A shock absorbing element is used to dissipate the kinetic energy of the element.
