Description of problem: I plugged my USB printer, clicked the + on the printer box from the gnome 3 control panel. It gave me local and network. Both were blank. If I used the system-config-printers it found everything no problem, the network printer and the local USB printer. I think there's something wrong with how the gnome 3 is detecting the printers.
What does 'lpinfo -l -v' say, as root? Also, how about 'rpm -q control-center?

CUPS can only see the cups-pdf device and serial devices. Presumably the printer was connected and powered on when you ran lpinfo? Can you please very that system-config-printer can find the printer? What device URI does it have?
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
