Kernel modules

The whole Kernel modules section is confusing. Is it mandatory? What exactly should we do?

Print button greyed-out in GNOME print dialogs

As suggested by the Arch wiki, I used the

  1. HostNameLookups Double

option. However, that resulted in following error message: IP lookup failed - connection from localhost closed!

and I wasn't able to add printers via the CUPS web interface (internal server error)

It seems there is an outstanding bug with respect to the HostNameLookups: http://www.cups.org/str.php?L4070+Qversion:%20-feature

Removing the HostNameLookups double form the cups config file resolved my issue. Not sure why this used to solve instead of create problems.

Device node permissions

I got a problem after update of hplip / cups and foomatic. My printer not working anymore.

So I first check possible problems and read section Device node permissions. It's recommended to verify that permissions are 660. It was my case so I am looking to find another solution.

After a long time and read I was back to this section. I read also section below Device node permission troubleshooting. As my conf was with well permission I don't really read all carefully. It was the 3rd/4th time before I see the note about 666 permissions. I tried this and it's solved my problem.

So I think it would be great to make also a note on Device node permissions about 666. Because my conf look allright as writing in wiki, but in fact not.

How to get the damned IP.

"Then add your cups server IP or hostname into /etc/cups/client.conf." ... begs the question how you get the freaking IP or hostname.Jasper1984 (talk) 17:30, 6 October 2012 (UTC)

Run something like ip addr on the server. Lonaowna (talk) 17:46, 6 October 2012 (UTC)

cups + systemd

Need more info for chapter "Installed Printers Do Not Appear in Print Dialogs After Installing/Upgrading to Systemd". Existing suggestions from article (change socket path, etc) does not help.
