Failed to print document - can't prompt for authorization

this looks similar: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=499759
are you sure the smb printer doesn't need authorization?
have you checked the printer's settings?

Dimitrios,

I can print with any other application to this NAS attached printer, including printing the same file with Okular. I'll try tonight hooking up the printer directly and let you know.

Yes, this bug looks a lot like http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=499759

thanks for so swiftly looking into my report.

I have exactly the same problem with the same settings. Every other application on my system print perfectly but not document viewer. So I use the acroread and it works without any problem.

Sounds like a GTK bug:

Please try printing with other GTK+ apps like GEdit or Firefox - this shouldn't work if this is a GTK+ bug, like it was reported on the blog post above. There's a kind of workaround on that page.

- Firefox = Not work
- Gedit = Not work
- Evince = Not work
- OpenOffice = Work

I can contribute.

- Firefox = Not work
- Gedit = Not work
- Evince = Not work

- Okular = Worked !
- Emacs (GTK) = Worked !

OK, so the bug is in GTK+. I've opened an upstream report, we'll see what they say.

GTK+ developers confirm this is a known limitation that should be fixed at some point. Don't know when, though.

I have the same problem. I use xpdf to open .pdf files and print them.

I realize I've missed something here: you said your printer does not require any authentication. So there's also a bug in the CUPS printing system, which sets up the printer the wrong way.

From the blog post quoted above, the problem is that the second line should not be present, and removing it is said to solve the bug. This is because the 'Guest' user (passed via the printer address) is does not need a password to print. Is that the situation of all reporters here?
<DefaultPrinter tp0>
AuthInfoRequired username,password
Info Canon_PIXMA_iP8500
Location
DeviceURI smb://Guest@Home/Desktop/CanonPIX

So what's the workaround, folks? Can you be a bit more specific? What file do I edit?

OK,

I found the blog entry that was linked to above: http://blog.avirtualhome.com/2008/11/21/cant-print-in-evince-gedit-claws-mail/ .

Apparently, in the /etc/cups/printer.conf file one can try commenting out AuthInfoRequired username,password, such that it becomes

# AuthInfoRequired username,password
Info SlicerDicer

Now, the other option is to enter a valid user on your network. You can do this through the GUI (system > administration > printing > change location ). Or, you can do it like so in the /etc/cups/printer.conf file:

AuthInfoRequired username,password
Info PrinterName
Location LocationName
DeviceURI smb://user:password@/COMPUTERNAME/PrinterName

If this doesn't work, then it's truly a bug.

I have a similar problem with IPP printing that requires authentication, and I think it's the same bug (or related at least).

I set up the printer (IPP) and the first time I printed I was prompted for a password, but it worked.
After this, however, I got the authentication error described above.

After som digging, I have it kind of working by doing this:
1. Changing the URI in /etc/cups/printers.conf from
DeviceURI ipp://<ipp-printer-server-adress>:631/printers/printer1
to
DeviceURI ipp://USER:PASSWORD@<ipp-printer-server-adress>:631/printers/printer1
2. Removed myself from the lpadmin group.

Now I can print using lpr or Acroreader (which uses lp/lpr), but I still can't print from Evince!

Adding the USER:PASSWORD in system-config-printer does not work, but manually editing /etc/cups/printers.conf did.
As a first try, I commented out the "AuthInfoRequired" line, but it crept back in when I restarted Cups!

Another thing which may or may not be related is that I can't change the printer settings for this printer that require authentication. [And yes, I tried it while still begin in the lpadmin group...]
If I use the Cups web interface, it works however. But it's not very convenient...

For me, this is the same bug has bug #283811.
Not sure which should be made the main one, here you have figure out that it affects GTK apps only, there,
the line that make it reappears in printers.conf is believed to be known, I am trying to figure out if it is right
or not by investigating the patch that added Auth-info-required in CUPS. (Just put it aside while I was triaging more cups bugs).

Has any progress been made as I'm having the same issues as above & have not had any success fixing it?

Got printing to work.. after an hour or so of google'ing and tinkering

I'm new to Launchpad (today) - didn't see where to post on the 'non duplicate or original bug...'

I have this issue on Ubuntu 8.10 x86_64 Intrepid. Printing used to work. Have not printed for a while from my laptop and now after numerous updates it only works for some apps like Openoffice but not for others like Evolution. Printer is a Brother MFC-8440 connected to a Windows Vista system via USB.

Anyway, I mucked around with the /etc/cups/printer.conf file without luck - different error messages depending on what I did - rotate between "Error printing. Can't prompt for authorization" to "Error printing: Too many failed attempts".

I copied the existing printer through the Gnome GUI and pasted it with a different name and then choose this new one as my default printer. Voila it worked fine from all the applications (no cupsys restarting needed).

Also, seems to me that config files being reverted and not keeping changes might have to do with debconf. If i recall correctly there's an argument to dpkg that allows reconfiguring pkgs so that they either don't use debconf or at least you can modify your configuration so it's configuration change takes ahold.

I did check the Vista System and Domain Event Logs to see if there were any failed auth attempts (yes auditing is turned on for this). There were none.
