摘要： Improved plotting and printing apparatus has a writing surface for supporting a printing medium and which has an opening for exposing the underside of the medium. A transparent plate is mounted to the supporting surface so as to permit placement onto that surface of a printing medium such as a plural leaf form set whose area is larger than that of the plate so that one portion of the medium extends across the opening under the plate and can be printed on by a printer positioned under the surface opposite the opening, while another portion of the medium lies on the surface beyond the plate so that it can be written on from above the surface.
