Device and method of non impact printing

A device for non impact printing of alpha-numeric characters on a sheet of normal paper, wherein an electrically conducting carrier is covered with an inking substance which is transferred to the paper by means of electrical pulses. The inked carrier is movable and is disposed against the paper on the opposite side to a print head provided with a plurality of electrodes and movable with a translatory motion with respect to the paper. The inked carrier passes through an inking station in which a series of rollers take ink from a container and, with a metered action, spread it on the carrier, thus renewing the efficiency of the layer of ink.
