A low cost, high speed printer which uses an electron beam to write on untreated paper at cathode ray tube (CRT) scanning speeds is disclosed. In this printer, a thin beryllium foil serves as a "window" which permits an electron beam to leave an evacuated vessel and enter the atmosphere without permitting air to enter the vessel.
