US Patent 7500798 Printer

A printer with an elongated media output port is disclosed. The printer may be used for a digital tachograph of a motor vehicle. The printer includes at least one bearing surface which limits the media output in the transverse direction and along which the printing medium slides during output. The boundary conditions for the operation of a small-format printer in a digital tachograph of a motor vehicle makes it necessary that the media output port has to be sealed off against the ingress of harmful media. Therefore, the media output port includes an elongate sealing closure which is movable in the transverse direction and presses elastically against the bearing surface by a sealing feed guide. The printing medium is capable of being outputted between the bearing surface and the sealing closure in an output direction.
