Hi,
I just installed CentOS 7 + KDE on a new workstation in my office. I tried to setup my printer, but the test page is blank. Here's some details.
The printer is an HP OfficeJet 8600 Pro. It works perfectly with all other desktop clients running Slackware Linux and HPLIP.
I installed hplip and hplip-gui, launched HP Toolbox and then setup the printer - a network printer - which is mainly a matter of confirming OK, OK, OK.
The printer shows up OK in HP Toolbox, but when I try to print a test page, the printer ejects a blank page, that's it.
Which leaves me clueless.
Cheers,
Niki Kovacs

Is there a .ppd for the printer in /etc/cups/ppd? Or is there a CUPS print server on another system (we have all ours basically go through one server).

This is a network-attached printer. All other desktop clients (Slackware) have CUPS + HPLIP running and can print and scan. Only the CentOS client refuses to work as expected.
Hmmm.

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?

[Much later.]
I just spent a few unnerving hours, and I found the solution.
The printer was working all along, as it seems. The only thing that's buggy is the "Print Test Page" button in HP-Toolbox, which produces a blank page. All other stuff like PDF documents works fine.

After I figured it out, I wrote a detailed blog post about the subject.

PS: on a side note, I wanted to discuss this subject on the CentOS Facebook group, but got blocked by their admin who seems to be the local pet autocrat. Links to CentOS-specific blog posts are disallowed as well as technical questions, so I wonder what this group is good for. Probably discussing the weather while running CentOS...

Try centos.org/forums instead.
I tend to avoid wiki sites to which I'm not allowed to contribute; maybe you'd feel like jumping through their hoops, though. i.e. see item 3 at wiki.centos.org/Contribute

As far as I understand, the CentOS mailing list is this distribution's primary form of communication. Please correct me if I'm wrong.

Hmmmm... /non sequitur/
My suggestion was an alternative to the facebork page cited.
