Printing Window Forms with scrollable panel

I've a panel in the Form and the background of this panel is set to an image which is of A4 size, to be able to view the complete A4 size form...i've set Scrollable property to true.... this is the point where I'm right now...from this point...I need to capture the entire A4 size of the panel into an image....I've done some research and found a method to print the content of the desktop...but I'm not able to figure out how I can get the entire scrollable panel which is of A4 size. I cannot do any re-sizing...any other solutions will be appreciated....
