A brand new clean install of Ubuntu 8.04 tells me it's printed when it hasn't. I look at the cups access log and it says "Not authorised" - that's the local cups. The printer is on a slug and the slug cups doesn't see the print job.

Just set up a fresh install of Puppy on a laptop on the same network and printed perfectly - so no problem with the slug or it's cups setup I assume.

Oh, the machine with Ubuntu had Mint (7.?) on it before and that printed ok. Before installing Puppy on the lappy, I tried Ubuntu on there. It wouldn't print either.

This kind of suggests to me a problem with 8.04. Googling reveals that one or two others have had the same problem, but I've seen no sign of a solution or confirmation that it is a problem with 8.04.

Oh, forgot to mention - the cups server on the Ubuntu box prints a test page successfully, as does the printer installation program. Try and print from any other app and nada.

Anyone have a suggestion?

Cheers.

Hi,

And welcome to LQ!

What do you see in the cups error_log for the successful
print jobs (test pages)?

And the obvious things: compare the puppy cupsd.conf with
the ubuntu one. The fact that the test pages work suggests
that it's just a config issue, not a problem with the cups
install as such.


Cheers,

Ok. Here goes:

The log files after a failed print of a web page from browser:

http://paulcarmichael.org/cups/access_log_19-7.txt
http://paulcarmichael.org/cups/error_log_19-7.txt

and 2 minutes later the test page:

http://paulcarmichael.org/cups/acces...st_page_ok.txt
http://paulcarmichael.org/cups/error...st_page_ok.txt

I haven't personally modified the cupsd.conf. When I have the puppy switched on I'll do a compare.

Here's the one from the ubuntu box:

I copied the cupsd.conf from the puppy (very basic config) and it made no difference at all to the ubuntu. Still prints test page but nothing else. It's something to do with users ie; the test page uses the correct user, but nowt else does.

Tried from command line:

paul@ubuntu:~$ sudo lpr <filename>
lpr: Unauthorized
paul@ubuntu:~$

So the only user that can print is cups itself.

This is the one thing that really makes linux difficult for most folk. Security is one thing, but for someone coming from that other environment it's a nightmare. I'd happily set security to "None", but I fear that's impossible.

After months of banging my head against a wall, I now have a solution to this problem, and *lots* of other people must have suffered the same thing.

It seems that by default, Ubuntu puts this line in printers.conf:

AuthInfoRequired negotiate

Comment this out and hey presto.

Now to try and get the XP box printing...
