The Printing Test Day for Fedora 20 is today.
This test day is for testing all aspects of printing, including setting
up the printer, sharing printers on the network, and printing jobs.
The changes in Fedora 20 are relatively minor: switching to CUPS 1.7 and
Ghostscript 9.10, and some improvements to cups-filters and the
"Printers" part of GNOME Settings.
Remember that CUPS unit testing is only one small part of the story:
printing is very much in need of integration testing. Try printing with
different applications, using options you don't normally use in the
print dialog. Try to see how many different ways you can break it!
If you have access to a printer and a machine running Fedora 20 (a live
CD is fine), please join in! We'll be on IRC at the usual place:
