Try adding group 'lp'
Although you probably already have that one.

What are your permissions on /dev/bus/usb/* ? That's what hplip tries to access.
On my system it's owner root and group usb, group usb might be missing on your user.

both lp & usb had to be manually updated indeed.
There may be a better way, I dunno.
It so happens this AIO also have wifi.
I may soon try to set that up.

Good to hear that worked.

Adding your user to the usb group gave it raw access to all USB devices which might not be what you want.
A more secure option would be (assuming you use some kind of udev) to write a udev rule that assigns a new group only to your scanner, and assign that group to your user. In that way you only give it access to your scanner, not to other USB devices.
The wiki seems to assume the sane daemon runs as root, that would solve the permission issues too
