Printing in Design Studio

I can't seem to find this anywhere in the forums, so I apologize if it is out there and I am duplicating someone else's question. I've created a button via Javascript in Design Studio and would like the button to send the form to the printer. I've tried using both portalWnd.print() and window.print(), but both have the same issue. Only a certain amount of the form will actually print. There is a vertical scroll bar on it, and unless I make the window big enough to show everything before I try to print the only data that will show in the printout is what can be seen without enlarging the form.

Has anyone else encountered this issue?
