Interface And Graphics :: Printing ALL Content In Large PictureBox Which Has Scrollbars?

My project needs to print a large PictureBox which during runtime only part of it is shown (as it's too large, width=4000 pixels and height= 2000 pixels) and to see the rest of the picturebox, user needs to scroll through the vertical and horizontal bars. On top of the picturebox, there are many controls which are loaded and positioned by user on run-time. Those include lines, labels, another picturebox
with image and user-defined controls. Now, i need to write a print function which will print that picturebox to not too many pages in A4 size or A3 size. Not too many means less than 5 for both paper size.

1) How can i print the whole picturebox with all its contents and go to next printing page until the whole PictureBox is printed? I tried using the following code but

(i)The image of picturebox inside that picture box and user-defined control are not printed whereas others are printed. Why is that so? How can i print the picturebox including both the "un-printed"?

(ii) Even i can print out the picturebox, only the part where the picturebox is shown is printed. How can i print the whole picturebox including those parts which needs scrolling to reach?
