Abstract
The present invention relates to a printing bar with a plurality of styli (10) for printing an image. It includes a first network of conductive tapes (1) insulated from one another and in which one end of each of them forms a printing stylus (10) and n diagonal matrices for addressing the styli whose columns are formed by the conductive tapes (1) of this first network and are fed via resistances (R) in electric contact with the tapes (1) of said first network and in which the rows common to the n matrices are formed by conductive tapes (7) of a second network and are connected to the columns via diodes (D) connected in the columns or in the rows. Application: a facsimile transmission installation.
