No problems there.

Your MTA is not listening on any IPv6 addresses -- that might be by design.
If that is so and if you're in the habit of telnet'ing to localhost port 25
to test things, you need to make it so that localhost resolves to 127.0.0.1
rather than ::1.  That depends on where your system finds the info from.  If
it's /etc/hosts then you can comment out the ::1 entry there and leave just
127.0.0.1.  If it's the DNS, and assuming you don't have any control over
the server, then you can try tweaking /etc/nsswitch.conf so that host lookups
consult /etc/hosts first, and don't go to the DNS if they find an answer in
/etc/hosts.

Perhaps easier in the long run to get your MTA IPv6 enabled.

Again, lpd is not listening on any IPv6 addresses.  According to the man
page it should default to listening on both IPv4 and IPv6 addresses.
You can try adding:

    lpd_flags="-46"

into /etc/rc.conf and then '/etc/rc.d/lpd restart'  That *should* be the
default, but it's worth trying.

Printing from the localhost will generally use the Unix domain socket at
/var/run/printer.  In fact, if all you want to do is print from localhost,
then putting:

    lpd_flags='-s'

in rc.conf is a good move -- that stops lpd listening on any network
interfaces.

Also check /etc/hosts.lpd for sanity -- you need to list hosts allowed to
send jobs to the printer in that file.

If the remote hosts you're trying to print from are not Unix machines, then
you may have to add '-W' to the lpd_flags to permit lpd to accept print jobs
where the sending side does not use a privileged socket.

Ah... You aren't running the system lpr/lpd then? That produces output more like this:

    happy-idiot-talk:/etc:% lpc status all 
    lp:
            queuing is enabled
            printing is enabled
            no entries in spool area
            printer idle

If that is what you intended, then you'll have to consult the manuals for the
printer daemon you are running and adapt the instructions I gave above
appropriately.

Also, if you describe what printers you have and where it might help -- the
above either shows a lot of attempts to connect to a network interface where there
is no lpd listening, or the effect of some overzealous firewall rules dropping
lpr traffic.
