I have now got my imac (Was a PC Lover) it is fantastic can't understand why I waited so long!!

So far I have only encountered 1 problem I cannot resolve, I am hoping yoiu guys can help me.

I have 2 printers and HP all in One 2500 series which the imac has seen and configured.

I also have an OKI C5600 Laser which snow leopard has seen but does not have a driver for. I have the original Installation disk (OKI) and have gone through the installation process. However snow leopard still cannot see the driver and when I try to tell it which driver to use I cannot find the driver I have just installed.

Can you help please
