I got the printer work fine with the Macs that have not been upgraded to Mountain Lion. When I try to add the printer to the upgraded Macs I get a message that the drivers are not available on the server. I think I downloaded the correct drivers from Brother. They are on my desktop. Now what do I do?
MacBook Pro (13-inch Mid 2010), OS X Mountain Lion (10.8.1), Brother 4570 Laser Printer
