Without any change to password.py the plugin will install with
sudo hp-plugin -i
So what was chrysn referring to?

The last entry is 8.6 on the versions line and only /etc/debian_version
has to be altered to 8.6.

If you are beginning to think I am not very used to the sudo command you
would be quite right. :)
As far as I can make out, a print queue and a plugin can be set up with
sudo. hp-doctor appears to be the only utility affected by the lack of a
root password on the system. I wouldn't rate its importance on the same
level as hp-setup and hp-plugin.
hp-check appears to duplicate hp-doctor's diagnostic ability and the
Missing Required Dependencies lists *-dev programs, which are not needed
to print and scan. Others programs listed as missing are known to be on
a Debian system; libc6, for example. And why cups-bsd is required is
beyond me.
Reducing the severity accordingly.
Cheers,
Brian.
