Even simpler than these posts. Plug your device in. Go to printers and devices . Click on 'add a printer' in the ribbon up top.. When the device appears, click on it and it will ask if you want to install driver. Say 'yes' and it will search the web based on the printer. It will install it automatically. The end.
Couldn't have made it simpler, except for all of this excess at the bottom. That's how I installed my HP Photosmart printer with out using the HP bloatware CD. If I wanted a half-assed version of of Photoshop, I wouldn't have spent $1k and simply downloaded PICASSA, HP!!!
