I would like to thank all of you who replied to my question and I was able to 
solve the remote printer problem. Message from IN%"ram_at_intercap.com" was very
helpful.
I was getting the following message (extract from my original message).
         >lpr -Prx1 myfile
         >lpr: cannot create /usr/spool/lpd6/.seq
         >The entry in printcap looks like this on both systems.
         >lp6|6|rx1:\
Below are the replies I received (all were great help!).

lpr should be setuid root.  Chances are that either you lost the setuid bit
or it's not owned by root or you've got /usr/spool/whatever across an NFS
mount.

Hi:
This is in reply to your remote printer problem.
Did the setuid bit on lpr change?
ls -l /usr/ucb/lpr
-rws--x--x   1 root     bin        49152 Aug  8  1994 /usr/ucb/lpr
          
## chmod 4711 /usr/ucb/lpr
