Yes, it really works (amazing, eh?).  We have 25 DECserver 100's, 8 MVII's,
and one 11/785.  The 785 and two of the MVII's are running VMS and the
other 6 MVII's are running Ultrix 2.0.  Here is a copy of one of my printcap
entries:

# Printers connected to terminal servers

	:fc#0177777:fs#06023:lp=/dev/ttyo0:op=PORT_6:ts=ISCTST:\
	:lf=/usr/adm/lpd-errs/lz22a:\
	:sd=/usr/spool/lpd/lz22a:

NOTE: you have to dedicate one LAT /dev/tty port for each printer (otherwise
listings can get confused).  Also you have to do an lcp -h tty??,tty?? for
each tty (to set it up as an outgoing port).  The instructions are on page
4-12 of the System Management Guide (Binder 3B).

We did have a problem with our printers just this week where the LPD daemon
was refusing to connect to the servers but rebooting the offending MVII
cleared the problem.  DEC Tech Support is aware that there is a problem but
is unable to re-produce it at will.

I have been told that your /dev/ttyXX lines must be the highest
numbered lines for this to work correctly.  For instance, if you have
/dev/tty00 - /dev/tty31 and you have three printers, then you must
dedicate /dev/tty29 - /dev/tty31 for the printers.
