I seems I was a little bit confused in my last comment, it should be:
This bug is definitely no duplicate of bug #24999.
The problem described here is that there are 2 printer models listed under "Detected printers" for HP printers. The solution for this bug requires changes in gnome-cups-manager.
Bug #24999 is about the fact that 2 duplicate drivers are listed in the "Driver" dropdown. That bug has been fixed.
