I purchased a Dell 1235CN laser multi-function printer, which arrived today. Unfortunately Fedora 12 doesn't know about the printer, so this lead me to the inevitable search for the right drivers.
I found a post by someone who had the same problem. She/he had called Dell support who told her/him that Dell did not support Linux for that printer, but that the printer is actually a rebadged Samsung CLX-3175 printer.
I visited the Samsung web site and was really happy to see that Samsung to a great job of supporting their printers on Windows, Mac and Linux. I was able to download a Linux tarball that contained the necessary drivers wrapped up in an easy to use installer.
After installing the tarball my printer was working.
Thanks to the people at Samsung! Excellent work for your top class Linux support.
