SWVB101,
You need to set up a PostScript printer somehow. This may be difficult if you do not actually have a PostScript printer.
Once you have a PostScript printer, you print to file.
GhostScript is a PostScript interpreter. It is very helpful once you have a PostScript file to play with. It will convert PostScript into whatever it is your printer understands, even if you have a nine pin dot matrix!
GhostSctript also creates TIFF, JPEG and PDF files from the PostScript.
GhostScript converts FROM PostScript, not TO PostScript, so it will not help you with SolidWorks.
