To activate the new printing system do the following:

- Copy these config files from ${PREFIX}/share/examples/LPRng
  to your /etc/LPRng/ directory: lpd.conf, lpd.perms and printcap

- set `lpd_enable=NO' in /etc/rc.conf

- add the following lines to /etc/rc.local:

if [ -x /usr/local/sbin/lpd ]; then
       echo -n ' LPRng';       /usr/local/sbin/lpd
fi

- reboot or kill the old lpd and start the new one 
  (`${PREFIX}/sbin/lpd')

- remember to adjust your aliases or your PATH to use the new programs
