Abstract
A print head for direct or indirect electrostatic printing comprises at least one row (21) of electrodes disposed at a regular pitch and organized in n groups (G.sub.1 . . . G.sub.n) per row, together with a counter-electrode (1) constituted of a resistive material extending opposite the electrodes in the row with n+1 conductive tracks defining n resistances in series (R.sub.1 to R.sub.n) and constituting access connections (C.sub.1, C.sub.n+1) thereto for selecting different groups of electrodes.
