new and strange printer problems
 

I'm running a standard 13.1 32 bit install with an HP deskjet 990C, run off of USB. Until today everything has printed properly. Now nothing prints. Nothing has been installed unless it came through slackpkg, and yes it is still on the correct setting for arch and revision. CUPS shows printer as installed, accepting jobs an idle. No error messages are appearing but nothing is reaching the printer. The info I can glean is from the error logs in CUPS:

The general permissions for these files (which I have not touched) do NOT include execute even for root. Since I don't know anything about these, thought I would leave it to wiser minds than mine. Do I just change permission in the relevant directories or should something else be done.

Have you tried removing the printer, restarting cups, and reinstalling it?

I did remove the printer, etc. I also removed and reinstalled CUPS. Neither made any difference to the problem.

On my 13.1 stock install 'ls -l /usr/lib/cups/filter/rastertogutenprint.5.2' shows:
The log entry suggests you have -rwxr-xrwx as permissions.

PS- What is the ouput of 'ls -l /usr/lib/cups' ?
I see:

It seems to be my mission in life to ask for help and then have magical cures appear. I removed and re-installed the printer one more time and that seems to have cured things. Personally, I think that there are M$ bugs floating in the nearby air. (My wife is a follower of the evil empire.) Thanks for the suggestions. I guess something got corrupted somewhere.

Solution - cups permissions
 

Long time user of LQ - know Jeremy...

... sorry to say I seldom post.

I followed the post mostly to the letter, and had been researching this on the ArchLinux forums.

I followed the python symbolic link change in this post:
https://bbs.archlinux.org/viewtopic.php?pid=851700

This did nothing that I could tell... HPLIP was already installed from months ago. I just settled for printing from a Fedora desktop.

Finally your post got me to thinking about the directory permissions. How?

I opened one terminal and tailed the error log:

while using the kde printer configuration gui. The errors keep coming...

Here are some of the messages:

I see permissions change all the time during pacman -Syu updates and don't think much of them. I change permissions for files when needed every day.

I thought hey, that's insecure like the message says, and tried changing permissions to 744. That was a mistake because the enable button suddenly became uncheckable in the kde printer configuration dialog.

I solved this by using the following:
This mystery is now solved in my opinion... I clicked print test page and it just worked!!!

Very sweet indeed!!

Now I can kick Fedora and Ubuntu and go full Arch!! - Happily using ArchLinux since January 2012 - Rolling release is the only way - once you try, you never go back.
