Can't scan since BIG Sure
HP Envy Photo 7855. I can't scan anymore and recently upgraded to Big Sur. Used to work fine before upgrade.
Tried all the advice i could find: until all HP software using HP Uninstaller. Install HP SMart andHP Easy scan. Won't connect to printer. Tried deleting printer and re adding etc. Keep getting error that it won't connect "failed to open a connection to the device - 21345".
I can print thankfully. But this is absurd!! Also tried Image Capture via Apple and it won't connect to printer either. Exclamation point in a triangle icon.
this is a brand new printer from xmas. Unacceptable. Ugh.
