/etc/init.d/avahi-daemon scripts says:

so it sounds like your printer knows how to identify itself. Newer
network printers tend to support zeroconf but you cannot assume for
sure that it will be there. Chances are not bad, as Macs wanted to
see that service for quite a while, but certainity is another thing.
Most likely a network printer is able to request an IP number via
DHCP but then you better configure your DHCP server to tie-up a
specific IP number to a printer interface MAC for obvious reasons.

That is an interesting port. "Sakura Script Transfer Protocol-2"???
Usually network printers will provide print services on some
combination of ports 9100 (i.e. jetdirect), 515 (printer) and 631
(ipp) ports. 'nmap' will tell you that if you will ask. :-)
Maybe because of this "Airport Extreme" in the middle which
sounds like it is doing a job of a printer server and in that
sense your R340 is not really a network printer at all?
The R340 is a USB printer.
Oh drat. Right. The port is 9101.
nmap reports:
Discovered open port 9101/tcp on 192.168.1.1
With a firmware update a while back, Apple switched the
Airport Extreme printer port from 9100 to 9101. This has
messed up the Gnome printer configuration tool in the past.
There was no handling in the config tool to automatically add
the "/" at the end when a non-standard port was used.
As I said, I think this is a CUPS bug.
