The msc ref man states they aren't supported (even if they are defined).

I think it is pretty clear why they can't work under os/2 the way one is
used to for dos,  and choosing not to support them is the best route I
think,  since the work around is so simple (fopen("prn",...) and
also works for dos.

IBM/Borland don't even define them.

Watcom considers them an extension (so stdprn isn't even ISO eh?  Good
choice on their part).
