Smartform Double side printing

Hi experts,

I have a smartform in which there are 2 pages.

Each page contains only one window that is main window.

So now i want to know How can i print some text on back side of each page.When i take a print out of Snartform i want to print some text on back side of each page.Is it possible?If so can any body let me know with some example?

I am sure of reward points.

Regards

Ravi.
