When I go in Control Center and click 'Print Settings', it doesn't open or do anything.

command, /usr/bin/python /usr/share/system-config-printer/system-config-printer.py display:

error raised: [load_xbel_store: couldn't load bookmark file [NULL]
]

I had to emerge these three files to get it to work:
cups-pk-helper, urllib3 & dev-python/requests

I assume they are missing from the Mate installation routine.

After getting Print Settings applet working (I'm still not able to get any print output) I ran the printer debugging process, the file is attached.

Thnx.
