-8133 is not a particular PostScript error. It is a general error number Macintoshes running MacOS 7, 8 or 9 use for any PostScript error that occurs.
Prior to displaying this number, your Mac probably displayed the true PostScript error during a couple of seconds. It looks like this: PostScript error: XXXX, Offending command: YYYY.
XXXX can be any of the standard 30- or so PostScript errors. YYYY is the PostScript command that caused the error.
Try sending your job again. See what the real PostScript error is and then look it up in this list.
