I wonder this because Ubuntu offers a driver, when I go to activate it, it fails to download saying "untrusted source". So why or how could ubuntu offer a driver, then say it is untrusted? So I tried to install my driver various ways from 3 different HowTO's, none were successful, so thinking security settings might be an issue. I ran the same printer on Ubuntu 10.10, but recalling that install, I had security/permissions problems with it, but not necessarily the print driver in that case.
Any suggestions, insights shared are appreciated.
