The company I work for recently purchased several new MacBooks for use around the office, but our Dell 3110cn printer doesn't seem to be compatible with them. It uses only a generic UNIX driver, so printing is extremely limited, and we can't change the printer settings for glossy, or heavy paper, leading to problems with posters.

To make matters worse, the only Mac OS X driver Dell had on their support page for said printer was for PowerPC based Macs. Because of this, they were incompatible. Can anyone possibly point me in the direction of a viable driver for our Macs? 

Thanks!
