Comment 6 for bug 314543

Can you try opening a document with: sudo gedit <document_example.txt>
then once it's open print it and see if you get the same error...

After looking at your cups error log It has several lines that might indicate a samba configuration issue. Can you take a look at this document and confirm this is how you setup your printing? http://www.swerdna.net.au/linhowtosambaprint.html

Also in my opinion you would have better results sharing the printer through your ubuntu http://www.swerdna.net.au/linhowtosambaprint_1.html.

Can you tell me which printer driver your using also?

It will not expire for a while, and I cannot confirm this as a true bug when i believe it is more of a possible configuration issue.
