Failure to maintain perspective view when printing to XPS Writer

Hi,

I'm using AutoCAD 2013 and am having some trouble maintaining a perspective view when printing to Microsoft's XPS Document Writer. In the plot menu, I choose print to XPS Document Writer and select the window that I'd like printed. When I select the window, it is in perspective view; however, when I preview it, it's not in perspective. Any thoughts on why this might be?
