We have SW 2011 SP0. There is a problem, if I have lots of large assemblies open, it wont print a document. Normally the small window that indicates printing opens, right before it starts printing. But with this bug, that small window won't show, so I know the printing wont start. If I close an assembly or two, I can print a document, but then it might stop again, so I have to close additional stuff.
I don't know if this issue was resolved later, but I'd like to know.
