Trying to add a Networked HP Multifunction printer

When I click the "Add printer" button an exception happens and the window stays where it was - printer isn't added to the list :/

hplip-3.10.9-2.fc14 has been submitted as an update for Fedora 14.
https://admin.fedoraproject.org/updates/hplip-3.10.9-2.fc14

I just test this packages. Device is rightly found, but when clicking to "Add Printer" button, "HP Device Manager - Setup" error window appears:

'Printer queue setup failed. Please add user to "lp" group(s)'

and printer isn't added.

Seems like some access problem.
I guess when you run hp-setup as root the queue is added, isn't it ?

Yes, when running as root, then printer is added.
But e.g. hp-toolbox isn't possible (as seems to me) run as root, it wrote:

Oct 15 13:48:15 ws22 hp-toolbox: hp-toolbox[16032]: warning: hp-toolbox should not be run as root/superuser.
Oct 15 13:48:15 ws22 hp-toolbox: hp-toolbox(UI)[16032]: error: dBus initialization error. Exiting.

This messages appears in all cases I was trying:
- run from gnome-terminal (after "su [-]")
- after startx as root from runlevel 3 (because gdm in default configuration refuse root login)

hplip-3.10.9-2.fc14 has been pushed to the Fedora 14 testing repository.  If problems still persist, please make note of it in this bug report.

This is bug #540721.

hplip-3.10.9-2.fc13 has been submitted as an update for Fedora 13.
https://admin.fedoraproject.org/updates/hplip-3.10.9-2.fc13

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

If you install 3rd party software, you need to report bugs in it to the 3rd party you obtained it from.  In this case, hplipopensource.com.

Fedora provides packaged versions of HPLIP which include bug fixes and adaptations for Fedora.  Bugzilla is for reporting bugs in these packages.

@Tim Waugh:
I think there is some misconception here.
hplip-3.10.9.run just a simple program which use to install,
1. hplip-3.10.6-3.fc14.i686.
2. hplip-libs-3.10.6-3.fc14.i686.
3. hplip-common-3.10.6-3.fc14.i686.
and other packages required to install the above three.

Also, the package that crashed is /usr/bin/hp-setup which is part of hplip-3.10.6-3.fc14.i686.

# rpm -ql hplip-3.10.6-3.fc14.i686

The hplip-3.10.9.run program is the automatic installer from hplipopensource.com, for installing the latest upstream version of HPLIP direct from upstream, without any of our addition fixes.  It is not a Fedora program.  It may have overwritten files from your Fedora hplip packages (you can check using 'rpm -V hplip hplip-libs hplip-common' as root).  In any case, see comment #9...

hplip-3.10.9-5.fc14 has been pushed to the Fedora 14 stable repository.  If problems still persist, please make note of it in this bug report.

I'm still seeing this with the latest releases...

Strange.
In my case it seems fixed with hplip-3.10.9-5.fc14.x86_64.
Can you verify the package with 'rpm -V hplip' ?
