  • Patent number: 6036380
    Abstract: An inkjet printer includes a plastic platen and a structural member extending upward from the base of the printer. The printing surface is supported by the upper surface of the structural member. This surface is held flat to within very tight tolerances. The bottom of the platen printing surface is retained against this surface so that it conforms to the shape of this surface structural member to create a substantially flat printing surface.
