A non-mechanical printer for use in an electrographic process comprising a drum-shaped data carrier, a recording head and a gas bearing for supporting the recording head on a cushion of gas in spaced relation to the data carrier. The data carrier is drum-shaped and the surfaces of the gas bearing which face the data carrier are correspondingly curved. The gas bearing includes porous walls for issuing pressurized gas toward the surface of the data carrier to produce the gas cushion.
