The device makes it possible to print, at a distance, posters in several colours. It comprises means for immobilising the support sheet (1) of the poster, and a mobile assembly (2) which can be moved along the longitudinal direction of this sheet and comprises: - an electrode holder/rule (10), making it possible to electrostatically charge the support sheet (1) at predetermined points, - an ink magazine (11), with several compartments, each receiving a powdered ink of predetermined colour, and - heating means (12). Successive displacements of the mobile assembly (2) allow deposition and fixing of the inks of different colours on the support sheet (1). <IMAGE>
