# /etc/printcap on host //beta

        :lo=/usr/spool/lpd/lpLock:\

    	:sh:\
        :af=/usr/adm/lpacct:lf=/usr/adm/lpd-errs:

The above are the two printcap files on the two respective machines
under SR10.2 on BSD4.3 environment.  I then created the following
on both machines (note that they are NOT links)
On //gamma
	% mkdir /usr/spool/lpd/lp
and the same on //beta.

Then I started the lpd daemon using 
	% /usr/lib/lpd & 
on //beta (Note that I am NOT successful using lpc start lp). All 
things go well after this, ie I can get things printed at lp when
SEND FROM //beta.

The next step as suggested in the manual BSD management which says
there MUST be ONLY ONE lpd running per network! So I send a file
from //gamma (NO lpd is running).
	% lpr -Plp /etc/hosts
After a few minutes, it says
	job queued, but can't start daemon
Puzzle!!!, so as suggested by message, I started the daemon using
	$ /usr/lib/lpd   
on //gamma.   WHY??? Something wrong with documentation??  OR am I
just being lucky it works (NB:two lpd daemons running on same network).

Next comes the tricky bits, ie, diskless node (Ah! //gamma and //beta
are both disk nodes).  So I went to a diskless node serve  by //gamma,
ie, //glenn and perform the same lpr command without creating  
/usr/spool/lpd/lp and running /usr/lib/lpd and I got
	job queued, but can't start daemon
and when I perform lpq -Plp, I got
	beta: /usr/lib/lpd: Your hosts does not have a line printer
	access.
What's wrong??
So I start up the daemon
	% /usr/lib/lpd &
which doesn't seem to make logical sense to me as there is NO /usr/spool
in //glenn (/usr/spool in //glenn is owned by //gamma) and secondly,
unless lpd is smart enough, when it looks for printcap file, it should
look into /sys/node_data.<node_id>/etc/printcap or else it will get
hold of //gamma printcap file.   So what should I do?

Thanks for all the help.
