Sorry about the delay, yes I agree this would be good to resolve before lenny.hplip also checks for the scanner group and adds it if necessary. But hplip also depends on libsane.Is hplip able to rely on libsane to add and remove the scanner group as required?
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.
Looking through launchpad[1] I see that they are now using HAL rather than the scanner group for access. Is that relevant to debian?
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.
