I've tried the uninstaller that came with the printer. Nothing.
I've tried downloading the officejet all-in-one "scrubber" from HP. Nothing.
I've even tried manually deleting everything labelled "HP" on my hard drive, and ended up just making a mess.
I've tried just re-installing the correct driver, and I get a message telling me that "a more recent version of this program already exists" and to "just connect the USB cable and everything will be alright." Or words to that effect.
HP tech support people were useless. HELP!!!
