Snow Leopard users with hardware from Hewlett-Packard should beat a path to OS X's Software Update feature. On Thursday, Apple released HP Printer Drivers v.2.5.2 for Mac OS X v10.6.
There's not a lot to this update, which promises anyone running Mac OS X 10.6.1 or later the latest HP printing and scanning software for Snow Leopard. Apple does provide a list of supported HP printer models at its support website, though. Apple last released an update for HP printer drivers in June.
