I have an Acer 5253 using win7 64bit, I installed an HP 5520 and it keeps trying to update through windows update...but after 3 days of it trying it will not install. It is tring to install an HP Null driver ?? so I tried to uninstall the entire printer, which I thought I did, but windows is still trying to get that driver....how can I make it stop trying to update a printer that's not even installed anymore. Any help would be very much appreciated. I've tried many different uninstall things but nothing stops that windows updater. Again my thanks for any assistance.
