If your printer supports PostScript, you may want to consider exporting
your graphic as Encapsulated PostScript with a TIFF preview.  The
format name as specified in the third argument to Display[] is
"EPS-TIFF".  The TIFF image will be used to provide an on-screen
representation of the graphic.  The use of EPS provides you with a
portable graphic that won't be constrained by image resolution.

There is one side effect that you may encounter in exporting your
graphics to this format.  You may need to configure your PostScript
printer to have the Mathematica fonts in memory when you print a
document with the imported graphic.  The Technical Support web site has
some FAQ pages that can give you some guidance on how to do this on the
Macintosh platform.
