i was going to ask about this myself, but in a different way...

what you are seeing is a change in Apple's Prep header (from Dict 65
to Dict 68) -- we are having the same problem.
on a VAX VMS system we usually download the old (Mac v5.x) Prep file,
and then can happily print %K-captured documents (on a LaserWriter II/ntx)
But if the source Mac is running v6.x, with the current Perp, we cannot.
We also workaround by putting the old LaserPrep on the Mac, and then everything works
(yes, we can run v6.x of system/finder, and have the LaserPrep be v5)
All attempts to get the new header to work haven't.
Among the tripups: there's a counted-byte string redefining some
 very basic PostScript verb (i think "get").  getting that into the
 LaserWriter unscathed was an amusement...
We at least got the system down to where it stop[ped sending back 
 "illegal command" error messages, etc.  Now it just happily
swallows the document (green light blionking serenely), and then
nothing.  the light stops and no paper nor error message(s) appear.
the next piece of normal PostScript gets thru just fine.
any help would be greatly appreciated...
