Hi Stephen, have you checked for the issue on your own system? I think all people have that problem but never understand it exists simply because never use the Illustrator the way I do.
I have tried it on Windows XP, Vista, 7 (all of them both x32 and x64) and 2000 with various printer drivers postscript, PCL and whatever more there are. This is an Adobe issue I believe, and in my opinion there is some problem communicating with the ppd file (although it is the same with non ps printer drivers).
