No, however CUPS does *not* try to convert level 3 PostScript to
level 2 - that requires the use of a PostScript interpreter (like
Ghostscript), at which point you are just as well off using a non-PS
driver...

BTW, applications are supposed to either tailor their output to the
PostScript level specified in the PPD or use the lowest language
level they support.  Always producing level 3 PostScript is a recipe
for disaster, and I'd file bugs against the applications that do that.
