I'm sorry, I don't know how to phrase what exactly is the problem. It's not that a printer doesn't work. It's that in the printer setup dialogue, where I presume it should list a gazillion printers, it only says, "No Printers Available". If I select "+" which I assume means add a printer and indicate either local or network and then press add, the dialogue rolls off the top of the panel and returns me to the initial printer setup page.
I haven't used Fedora/Redhat in over ten years and of course, I've never use Gnome 3 so I don't know how this applet is supposed to act or look. is there a setup guide?

Update, I flushed iptables and when I clicked "Network" it found my HP "Photosmart-D110-series" printer. I selected add and it went out and thought about it for nearly a minute before presenting a yellow flag indicating failure. Notwithstanding this, the printer panel now shows the D-110 to be present and active. Still, no print, I tried "print a a test page" and i loaded LibreOffice Writer and tried to print a document. No joy. What am I still missing.
