hplip tools doesn't work

I've installed hplip and printing works, but I can't get the hplip command line tools to work:

[lars@laptop ~]$ hp-levels -g
warning: python-dbus not installed.

What's wrong? hp-info gives the same error. Doesn't these tools work with my HP PSC 750xi?

Re: hplip tools doesn't work

Installing the printer with hp-setup instead of via the CUPS web interface got me further. Now hp-info works, hp-levels still doesn't:

[lars@laptop ~]$ hp-levels -g

Edit: hp-levels works if I run it as root, but not as a normal user. It says itself though, that it should not be run as root.
