You will get problems if the remote host "BSD-machine" is down, or not
available across the network for any reason.  We have a similar setup and I
found that it was necessary to test the result status from rsh (well, we have
rcmd on our TCP/IP implementation) and retry after eg 30 seconds if the
connection failed.  Thus you get (approximately),

:   while :
:   do
:	if cat "$MYFILE" | rcmd "$RHOST" -l "$RUSER" lp ...
:	then
:	    break
:	else
:	    sleep 60
:	fi
:   done
