Rolling on with the Fedora 15 Test Days, we have the Printing test day
This event will focus on all aspects of printing; including printer
setup, printer sharing and printing jobs.
In previous Fedora releases the application used in GNOME for
configuring printers was system-config-printer. In GNOME 3 parts of that
application are being replaced by more tightly-integrated functionality
in GNOME itself:
* print job notifications are now implemented in gnome-settings-daemon
* status feedback is expected to be implemented there soon as well
* a new control center module for printing has been implemented
Full instructions are available on the wiki page  and there will be
people in #fedora-test-day on Freenode IRC throughout the day.
Please help out if you have the spare time. Thanks!
