The printer disappeared one day and I can not get it reinstalled. With no HP software showing under programs and features except 8620 help. Tried to install the full software package and it only does a basic device installation - it thinks the printer is already installed. HP scan and printer doctor does not fix the problem, it wants a full installation done - no can do.
Need a tool to completely remove all HP printer software and registry items. I have a laserjet that uninstalls and reinstalls correctly, but it is a printer only.
Thanks for the reply, this is for my client's PCs and I'll give it a shot next week.
I just found out yesterday that their second PC had scanning issues and could only get it working by reinstalling the 8620 via usb. When I shared the printer to the original problem PC, it would connect, but would not print. Running the HP printer diagnostic, both showed a network 8620 printer that does not show up under devices and printers. On the second PC I was able to install the printer via Windows "add a printer" which naturally allows printing, but not scanning.
I think a recent Windows 10 update started these issues.
