lexmark z42 and knoppix 3.4

Hi:
I am trying to install my printer ( lexmark z42 usb ) in my new knoppix through cups ( localhost:631 ).
I click in add printer, give a name, location and description.
Device is USB Printer # 1 (Lexmark Z42), click on continue and when i get the next screen there is no support for lexmark, I only get RAW, DANKA, DIMO, EPSON, HP, OKIDATA.
How do I add support for my lexmark printer? I had it installed in my old knoppix and it worked perfect. What happen?
thanks

Make sure you have all the foomatic and ijsgimpprint pkgs on your system (foomatic-db-gimp-print and dependencies). I have a z43 which I had a hard time getting going with kanotix and newer knoppix though knoppix 3.3 installed fine. The only driver for my z43 that's working for me is just the z43 foomatic/gimp-print-ijs, the "recommended" driver which is z42/43 didn't work.

I probed with this driver and works perfectly, thanks so much
