No I have not been able to resolve this problem
Hopefully if it is something to do with Fedora then the issue will be fixed in the release of core 2.
I tested core 2 test 2 and the problem is still there, so I am guessing it is a permissions problem within windows sharing the printer.
Hopefully someone with great knowledge of both windows and linux will read this post and give a helping hand.
Please help - anyone!
