Fixing “/usr/lib/cups/backend/smb failed” error in Ubuntu
By admin | January 16, 2010
CUPS server showing error
The new setups for printing has been modernized in Ubuntu 9.10 and 9.04 work perfectly most of the time, but sometimes a misbehaving script or update decides to have its own mind and messes up all the permissions for CUPS to work properly. Here is a guide to restore the former printing versatility before the mess-up.
To fix the permission errors:
sudo chown root -hR /usr/lib/cups/backend sudo chmod 755 -hR /usr/lib/cups/backend sudo aa-complain cupsd sudo chmod a+x /usr/lib/cups/backend/smb sudo chmod a+x /usr/lib/cups/backend
Also make sure your Windows printer is actually accessible in order to prevent further access issues. In addition, to access the CUPS web interface just navigate to http://127.0.0.1:631/. When it asks for your password, use your Linux login.

Thank you so much, my printer was down for 3 days after I added CUPS-PDF, and now I realize that while I was getting it to work (and needing permissions things), that it broke SMB.
I cut and pasted, made a script and now the ‘Windows Printer via SAMBA’ option has returned.
Thanks again, your a life saver.

I’ve had 64 bit Kubuntu 10.041LTS installed on my laptop for over a year and could never connect to my samba network printer. My Fedora desktop always worked fine. Your permission fix resolved the problem. Thank you very much! It’s too bad it took me so long to find your web site.

[…] I am doing this on a clean install of Ubuntu 12.04, CUPS version 1.5.3. I have tried changing some rights relating to apparmor, with no success as described here: http://www.compdigitec.com/labs/2010/01/16/fixing-usrlibcupsbackendsmb-failed-error-in-ubuntu/ […]
