Printing of form Billing Document as 3 copies each time with mark as Original, Duplicate and Triplicate

Hi all,

I had a requirement to print the form Billing Document each time for 3 copies with mark on every copy as Original, Duplicate and Triplicate separately. How to achieve it?

We can give no. of copies in Output Parameter Determination. But, the requirement is as above.

Please suggest me...

Thanks,
