Abstract: An electron gun printer, having an electrically insulating vacuum enclosure, in which is located the gun, which gun emits an electron beam to a printing medium outside the enclosure, a focussing anode for modulating the intensity of the beam, deflecting coils or plates controlling an alternating movement of the beam to scan the lines of the printing medium, motor-driver rollers for controlling a displacement of the printing medium and a clock for synchronizing the anode and deflecting coils. One enclosure wall has at least two rows of windows arranged in staggered manner parallel to the scanned lines and respectively sealed by conductive plates, which are transparent to the electrons. The printer also includes plates or coils for deflecting the beam so that the beam alternately scans each row of windows during the displacement of the medium.
