Ok, I'll admit it's just *my* experience....
...but i have *never* had the Windows driver wizard *ever* find a driver for *anything* on the web, EVER. Not Win7, not XP, not 98se... trying to install a printer in anything but Linux is a Massive PITA ... yes, i said Linux. Average install time in Mint for my hp colour laser 4650 is 4 seconds (time it takes to get the drivers from the repository). Windows *any* flavour (well, not 8 - not going there)? Without the disks... 22 minutes, much of which is trying to remember what the bloody printer was named so WinX can find it.... and IP address doesn't suffice.
