Well, since the "JetDirect protocol" is just a raw socket interface,
there is little we can do to duplicate the Windows port monitor
functionality.

What we'd need would be the specifications for the protocol the
Windows driver is using (it could just be a PJL layer or something
similar over port 9100) in order to support it natively in CUPS,
probably via a custom backend.

Alternatively, if the printer supports IPP, you'll get this for
free already since the IPP backend is specifically written to only
send one job at a time...
