Cups prompts for authorization on a network printer even though it is not required

What I expected to happen: Printing to a network printer without being asked for authorization
What actually happened: Authorization was requested when trying to print to the network printer

The printer in question is on a Windows XP machine and is accessed through a Samba share.

Steps to reproduce:

1. Install a Samba shared printer that does not require authorization by going to System->Administration->Printing
2. On the wizard screen under Authorization leave the default setting, "Prompt user if authentication is required"
3. Print and be prompted for authorization

Details:

I get asked for authorization with every print. I can leave the password blank or put anything at all in the username and password fields and the document will print. It shows up as "Guest" user on the XP machine.

Workaround:

I tried changing the setting for the authorization to guest with no password but the change did not persist. This seems to be another bug which I will file separately. I got rid of the prompt by deleting and recreating the printer and setting the username to "guest" and leaving the password blank under authorization.

The AuthInfoRequired setting in printers.conf is assigned automatically and cannot be overridden by simple edits. The assignment on my system and with my configuration choices is "none", which should disable authentication altogether. Instead cups prompts for the password for a username "none".

AuthInfoRequired is set to 'none' in printers.conf.

https://help.ubuntu.com/10.10/printing/C/printing.html and all the other documentation does not mention the following procedure for printers that have already been added:
System Settings->Printing
Right click on the icon of a printer
"Enabled" should be checked.
Sometimes "Shared" should be checked.

The enabled and shared checkboxes may not have been there when the document was originally authored.
Otherwise, close this bug.
