Firewall open on the port... no, you said it sends some signal, since it prints out a blank page. And CUPS on your box is configured to understand the printer, right?
I have a few sandbox machines in this office, so I experimented some more, and here's what I found.
1. 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?
