[gentoo-user] epson printer

[Bill Kenworthy]

Hi, Ive just bought a new epson wf-3520 MFP and want to get it to print
through cups over wifi for preference.

Question 1 - do you have to be on the (same) wireless network to print
if using wifi? (i.e., I have a complicated set of networks and want to
print via a LAN to the printer on a separate routed wifi network -
connectivity exists but I cant get it to talk to me.)

Question 2 - what stanza do I use to connect?
(ipp://192.168.41.72:631/what?/, or is it http?)  This information
doesn't seem to be available with ubuntu folks etc just saying "it
works" - I suspect cups browsing on the same network)

Most modern printers have an embedded web server. You may be able to
just type in the IP address into your web browser and establish a connection
to the printer's internal web server. Give it a whirl...

if you have installed and configure cups, you should have this file:
/etc/cupsd/printers.conf

and an entry like so:

DeviceURI socket://10.20.30.69

Thanks, now working.  The socket interface works whereas my old printer
used usb - wireless seems SO much nicer, and I don't need to run raw
queues for windows and fragile bonjour services via cups anymore -
win-win :)

The web server is also a great idea - but the (lack of) documentation is
a problem when they don't tell you it exists!

It may also have a telnet daemon running, or snmp.  Worth investigating.

No telnet but it does seem to do ipp - is there a way of finding the
queue name?

You don't need a queue for ipp, unlike say for lpd:

http://www.cups.org/documentation.php/network.html


From the results above it does not seem like ipp is supported (you got a 405) 
but I am not sure.  You can try this to see if it reports an ipp or other 
server version running on that port:

 nmap -A -T4 -P0 -vvv <printer's IP address> -p 631
