	We are doing a slight variation on cnode printing.  In order
	to standardize the interface scripts and support programs for
	interface scripts we CDF'd the interface script and placed the
	following script under the servers script and the desired
	interace script under the diskless clients interface script.
	This also means that we made no changes to any interface script.
	
	Here is the servers interface script 
		(/usr/spool/lp/interface/sleepy+/<server>):

#!/bin/ksh
parms=""
for parm in "$@" ; do
  parms="$parms \"$parm\""
done
cnode=$(line <member/${0##*/})		#extract printers device
cnode=${cnode##*/}			#assume last field is cnode
remsh $cnode $0 $parms ">/dev/"${0##*/}

	Each printer's device is "/dev/cnode/<diskless cnode name>".
	This displays in lpstat and removes the name from the interface
	script.  The script assumes the diskless cnodes name is the 
	last portion of the device name and that the executing 
	script ($0) is a cdf.  We also make the actual device name
	"/dev/<printer name>".
