Actually, I believe this displays a QuickDraw version of the file.

For instance, if you were to create PostScript code in WORD, this
would print out on a LaserWriter as a PostScript image, but not on
an ImageWriter, and would also not be previewable in this manner.
Any time you have a Mac program that cannot generate a QuickDraw
file useable by an ImageWriter, you will not be able to preview
it with one of these printer-intercept programs.

You need an actual PostScript interpreter. There are programs that get
feedback from your connected PS printer and put this back onto the
screen. One would also think that something like Freedom of the
Press, which interprets the PostScript output of Mac programs,
would be somehow useful in this regard.
