I bought this computer with Linux pre-installed because in a dozen or so tries on different platforms I never got a single Linux install to survive the first reboot. Mandrake is somewhat lame compared to the Knoppix CD I downloaded before leaving my previous employer, but at least it runs. However it's unable to print to this HP 3520. Knoppix does!

Which is easier, ordering Knoppix install CDs (where?) and risking destroying everything, or copying the printer driver from the Knoppix boot CD onto the Mandrake system? How?
