ABAP Objects - Printing Graphical tree

Hi All,

I want to print one graphical tree structure into spool or to printer. For this i am currently using

if_graphic_proxy~print method.I have a button on application tool bar, which when clicked calls the above method. But nothing is hapening.I doubt if the graphical tree is printed.

Help me out.

Useful answers will be rewarded.

Thnx,
