If you want to print, I think you need lpd or inetd listening on this
port, but you can restrict it to localhost by setting something like
lpd: ALL EXCEPT in /etc/hosts.deny
I don't know, if lpd is respecting this file, so starting it by inetd with
a line like
printer stream tcp nowait root /usr/sbin/tcpd /usr/bin/lpd -i
in /etc/inetd.conf could be better than lpd standalone.
If you don't want to print, just set START_LPD=no in /etc/rc-config or
deinstall the lpd-package.
Hope, this helps!
