Well, for a really insane solution you could configure a "dummy"
printer in Samba/iX and make its "print command" in smb.conf run
the FCOPY needed to feed the data into the MSG file. Then your
NT machine could COPY or ECHO the data to \\your3k\dummyLP to
remotely feed data into the MSG file -- as I said, really insane.
