cups is resolved locally.

tim@dirac:~ (none)$ host cups
cups.home.woodall.me.uk has IPv6 address 2001:8b0:bfcd:100:...

ippfind complains about bonjour not running. And it looks like I'd need
to add some more dns records based on my quick glance at the manpage

lpinfo -v doesn't give me what I want either:

root@dirac:~# lpinfo -v
network socket
network beh
file cups-brf:/
network lpd
network ipps
network http
network ipp
network https

root@cups17:~# lpinfo -v
Password for root on cups?  ********
network socket
network beh
file cups-brf:/
network https
network ipps
network ipp
network http
network lpd
network socket://192.168.100.23

That last one is the actual printer (which is only ipv4). dirac is ipv6
only ATM but currently on the same network segment.

Does all of this point to something being wrong on cups (who, to confuse
even more, is really cups17)?

My wife's windows machine can also successfully print via cups17.

This is what I get with current config:

root@dirac:~# lpq
Samsung_SCX-4x25_Series is ready
no entries
root@dirac:~# lp /etc/nsswitch.conf
request id is Samsung_SCX-4x25_Series-1164 (1 file(s))
root@dirac:~# lpq
Samsung_SCX-4x25_Series is ready and printing
Rank    Owner   Job     File(s)                         Total Size
active  root    1164    nsswitch.conf                   1024 bytes
root@dirac:~# lpq
Samsung_SCX-4x25_Series is ready
no entries

That must be going via cups as dirac has no ipv4 addresses. (other than
127.0.0.1)
