I don't have lpr/lpd ported (I'd want it, if someone does have it,
even diffs to some specified BSD distribution would do!), but I have a
way to make printers on the BSD side of the network available to
386/IX machines. It requires that user ids are equivalent across the
network, but could probably be modified to use an id like "nobody".

Here's how to do it:

1. For each network printer, create a device with the same specs as
   /dev/null, but with the name /dev/printername. I.e., our laser
   printers are named h0, h1, etc., and I have devices created like
   this:
	
	mknod /dev/h0 c 2 2
	mknod /dev/h1 c 2 2
	...
2. Then go into the sysadm menu, select package mgmt, lp mgmt, add
   printer.

   Specify "dumb" as the type, regardless of what type of printer it
   is, we'll let BSD lpr handle the filtering etc.
   Specify the appropriate /dev/null equivalent as the device. This
   will work, even though /dev/null, or the printer-specific equivs
   are not listed.

   Give your printer an appropriate name (instead of dumb1, dumb2,
   etc.).

3. Finally, cd into /usr/spool/lp/admins/lp/interfaces, and modify
   each of the scripts there to do something like:

	#ident	"@(#)tcpremote	2.4 - 88/07/21"
	# lp interface for remote printer on a BSD-like system
	#
	
	PRINTHOST=cossun	# modify to suit local setup
	THISHOST=`/usr/ucb/hostname`
	LPRDEST=`basename $0`
	REQUEST=$1
	OWNER=$2
	TITLE="$3"
	if [ ! -z "$TITLE" ] ; then TITLE="-T$TITLE" ; fi
	COPIES=$4
	OPTIONS=$5
	shift; shift; shift; shift; shift
	FILES="$*"
	export LPRDEST REQUEST OWNER TITLE COPIES OPTIONS FILES
	(count=1
	while [ $count -le $COPIES ]
	do
		for file in $FILES
		do
			cat "$file" 2>&1
		done
		count=`expr $count + 1`
	done
	exit 0
	) | /usr/ucb/rsh $PRINTHOST lpr -P$LPRDEST -C$THISHOST -J$REQUEST

And off you go.
