How to print Server Models from Designer

My problem is the next: I want to print a lot of models from designer, but they doesn´t fit in a single sheet. I thought to print them towards a plotter, but I don´t have one, so I need to export the model to a compatible format, in the present case, Autocad 14 or Gif, so I can print them in one large sheet. But Designer only generates postcripts file.

Anybody knows how can I export the models to a diferent format, or a method to can get that? I tried installing an Apple LaserWritter printer, but it only supports US Letter size.

Thanks a lot
