The problem you are encountering is rooted in the fact that Mathematica uses a collection of fonts to do typesetting that are not (by default) available to your PostScript-rendering software. The fonts are used to typeset mathematical symbols as well as Greek letters. Many users (mistakenly) assume that Greek letters are drawn using the Symbol font. I think it's using a variant of the Math1 font. The EPS file created by evaluating Display contains requests for fonts, but it does not include information on how to draw the Mathematica fonts. You can make your PostScript interpreter aware of these fonts by reviewing the documentation for the interpreter. If you are using Ghostscript or a viewer that employs Ghostscript (like GhostView and xdvi), then you will need to either edit Ghostscript's "Fontmap" file (good if you are a sysadmin and want to make this available to all users on the system) or you will need to define an environment variable GSFONTPATH to tell Ghostscript where to find the Type 1 versions of the Mathematica fonts (good if you are just a regular user on this system and can't edit Fontmap). See the Ghostscript README files for more information. I have template Fontmap files for doing this under Linux and Windows 95 that I can supply at your request. This will affect you when you try to print a PostScript file with these fonts as well. The Technical Support department at Wolfram Research has put together an extensive explanation of how to make PostScript printers aware of the Mathematica fonts.
