SOLVED ! FIXED! 3 days of endless searches through forums on and off and changing configurations and it finally paid off, I figured this out on my own and everything came to life, automatically detected all my printers.
Ubuntu 12.04 LTS OS install has an incorrect file name for network management.
Old : /etc/NetworkManager/NetworkManager.conf
New: /etc/NetworkManager/nm-system-settings.conf
The only way I found this is because I have a older computer that will only run Ubuntu 10, just happened to see that they were different. I hope this will go up to the developers so they can make changes for the next updates. So glad this was found, because I would hate to lose Ubuntu 12, other then this problem it has been one of the best OSs I have used.
