Apple released Fuji-Xerox Printer Drivers v2.4 for OS X on Thursday. The patch notes don't specify what's new, saying simply, "This download includes the latest Fuji-Xerox printing and scanning software for OS X Mountain Lion, OS X Lion and Mac OS X v10.6 Snow Leopard."
Exciting stuff, and a 40.25MB download from Apple's update site. If you have a Fuji-Xerox printer installed on your network, you'll find the driver update in Software Update in Snow Leopard and Lion, or in the Mac App Store in Mountain Lion.
