CUPS speaks IPP. Windows speaks IPP.

True, but it's irrelevent since Windows has supported IPP since
Win2K.

That's going to quite a surprise to all the people who print to
CUPS servers from Windows.

You can either set up a postscript printer under Windows and
point it at a "cooked" CUPS queue or you can set up a "raw"
queue on CUPS and point Windows to that (with the appropriate
printer-driver installed under Windows).

Googling for cups, windows, ipp will provide lots of
documentation and hints.

Good start

That looks right.

Strange. I've just fired up a copy of Windows XP and added
an "Internet or home/office" printer with a similar URL,
http://{servername}:631/printers/pixma. This paused for a few moments
and then asked for me to choose an appropriate printer driver.

I can get that message if either the server name cannot be resolved, or
the protocol ("http") was mistyped. You can reach the server, as named,
from the Windows box, can't you...?

It might be worth looking in the CUPS access.log (on your server) to
see whether the Windows XP box even tried talking to it.


> Tried it after turning XP firewall off. Didn't help.

The standard firewall shouldn't matter, since you're not trying to talk
to the Windows box from your Linux server. If you've got something
fancier I would have expected it to ask for confirmation of the outgoing
connection to port 631 (which you clearly would have accepted).

You don't need SAMBA; what you've tried to do is quite reasonable.

Take a look at http://bbs.archlinux.org/viewtopic.php?id=71673, starting
from the fourth message, "No, I have to correct myself. [...]", which
has some suggestions that may be of use.

What provision have you made for the Micro$loth Windoze XP machine to
get the IP address of the <server name> ?

From the Windows XP box have you checked also

1) ping server_IP
2) ping server_name
3) using the IP instead of the server_name in the URL

This may not be the cause of your problem but you should still make
sure that it is working.

Ping it fine, using either ip address, or name (I put it in my hosts
file on the Windows box).

In fact, tried suggestions (1), (2), and (3) - nada.

I'm starting to wonder if the XP wizard itself is broken - at least on
the machine I'm using. I'll try with another machine, and will report back.

Tried ip number, name, and alias (after putting ip in Windows hosts
file) - made no difference.
