The checkbox to enable showing printers shared by other systems also seems to be gone from localhost:631/admin, and enabling local printer sharing currently breaks CUPS entirely: the system-config-printer-gnome applet will no longer connect to CUPS, and localhost:631 will reject the connection (Error 102 with Chromium). The only way to be able to log in again is to purge and reinstall the cups package.
