How to Uninstall Level Four for the HP C4280
Performing a "Level Four" uninstall of your HP Photosmart C4280 All-in-One Printer completely removes all traces of the device from your computer. It uninstalls not only the software required to run the printer, but the device driver from your hard drive and all related entries from your registry as well. If you ever need to use your HP C4280 again after performing a "Level Four" uninstall, you will need to completely reinstall all software and hardware onto your computer.
