Vanilla installation of CentOS 7 + GNOME = works fine 2. Custom installation of CentOS 7 with KDE = prints blank page So I guess the RHEL maintainers forgot a little dependency somewhere. By the way, when I print from the KDE client, a peek in /var/log/cups/* shows me that everything is fine, even though the printer printed a blank page. So... printer ejecting blank paper, CUPS thinking everything's OK, what package might be missing?
