Sorry for the comment #12. If plug-in is not installed and running hp-setup: hp-setup will launch hp-plugin to install plugin. and the invocation of hp-plugin by hp-setup is depends on weather policy-kit is enabled or disabled. if policy-kit is disabled then it will check for GUI tools in system to request to user to take username and password. if policy-kit is enabled then policy-kit should take care about it. running hp-plugin as standalone will also work like the above.
This issue, Looks like there is an issue while invoking policy-kit from HPLIP, not from Ubuntu.
