I'm also having difficulties with an HP USB PSC 1210 Inkjet. Knoppix 3.7, 3.8 & 3.81 recognized the 1210V , but verion 3.9 doesn't see it. I Guess I'll have to wait for 3.9.1. Maybe there wasn't enough space left on the CD for the printer drivers ? Oh my, and I have no DVD burner. Guess I'll have to order it though Linux Centtral
