If libsane manages completely that the scanner group exists throughout 
the whole presence of libsane, HPLIP does not need to take care of the 
group. If libsane does so only from a given version on, then make the 
dependency in HPLIP versioned.

I do not know whether Debian switched to HAL, too. If so, one could drop 
the scanner group even in libsane. In general I would keep the scanner 
group, so that the admin can add (trusted) users to the group scanner if 
they want to scan from an ssh login or if the machine provides desktops 
to remote machines through tools like VNC or NX.
