I have a Hawat-Pickford 520xz ink jet printer without PostScript, is there anyway I can print PostScript files on it?
Yep. There are a number of PostScript interpreters which run on your computer and can print out PostScript files. There are versions of these kinds of utilities for the Mac and for DOS/Windows machines. I have never used one of these utilities, so I can not recommend any particular one. Go to your friendly neighborhood dealer or your favorite catalog to see what they have. There is a section in the PostScript FAQ on this issue. You may also want to have a look at GhostScript. GhostScript can print PostScript files on certain printers.
