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?

And CUPS on your box is configured to understand > the printer, right?[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.

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... -- Microlinux - Solutions informatiques durables 7, place de l'?glise - 30730 Montpezat Web : http://www.microlinux.fr Mail : info at microlinux.fr T?l. : 04 66 63 10 32
