I've got the external parallel port driver BLUES! I asked this question some months back and although satisfied with the answers given, I still want to keep trying.
Bascically I have this parrallel port cd drive I bought on ebay.
Multi-Systems technology Inc, But no software and I've been tearing my hair out ever since.
I've searched the internet high and low, no joy.
Have a look at the old Question for details of the drive.
