As suggested by the Arch wiki, I used the
# 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
Device node permissions
I got a problem after update of/ 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.
Is libcups really sufficient as a client package ?
I can't seem to be able to print in KDE applications (4.9.97) if I only have libcups installed:
Could not print the document. Detailed error is "Could not find a suitable binary for printing. Make sure CUPS lpr binary is available"
Foomatic not providing drivers?
I don't know if this is a general-enough problem to be put on the wiki, but I was unable to print using my Konica-Minolta PagePro 1350w because the driver was not installed with foomatic. I installed foomatic-db, foomatic-db-engine, and foomatic-filters, and used the CUPS web interface to add the printer and select the recommended min12xxw driver. I was unable to print, and only got uninformative error messages in the logs like "Filter error". The Gnome printer dialog, however, said it was unable to find the driver, so I tried installing it from AUR (https://aur.archlinux.org/packages/min12xxw/), after which I was able to print. Why was the driver listed in the CUPS web management interface, but not actually installed? Maybe a note on the wiki will help future users.
Gnome Printing Workflow
In my test Gnome 3.8.1 print workflow no longer requires to install system-config-printer. It should be removed from this wiki, also i am not sure if lpadmin is required either.
The link to "ufr2", which points to the AUR, is dead. Is there an up to date link?
