Getting updates to Fedora 15

[Jim]

I have a live CD for Fedora 15, can I still get the updates for Fedora 15.

The Print drivers I have for My Samsung Color Laser CLX-3175FN just 
won't work in Fedora 17 or 18 because of Glibc updated packages.
The printer worked great on Fedora 15.

The foo2qpdl driver will work for this printer but it doesn't print in 
Color, Got to have Color.
Ghostscript won't even work with foo2qpdl anymore.
