Hi, I'm trying to connect a printer to my iMac. I have downloaded the printer driver, but when I try to access it via the 'add printer' section it is greyed out ( as are the majority of other files and downloads) 'Help please! Thanks.

Kodak has posted an unsupported hack that has been reported to enable printing to a Kodak printer not supported in OS X 10.10 ("Yosemite"). Perhaps it would have the same effect with some other kinds of printers that aren't supported in Yosemite.

I have not tested the hack myself. As far as I know it will not break the compatibility of printing software that is already compatible with Yosemite. It may degrade the security of the printing system. It's up to you to decide whether that risk is worth taking.
