ABSTRACT:
A matrix printer comprising a printing head which is pivotable, under the influence of the braking effect of a magnetic field, about an axis which is perpendicular to the line direction and to the surface of the paper to be printed. The different printing positions of the printing head realized by said pivoting motion are utilized for printing characters with a comparatively good recognizability at a comparatively low printing speed or, as desired, for printing characters which are less rapidly recognizable at a comparatively high printing speed.
Matrix printers of this kind are used, for example, in text editing systems.
