How to output group foot at bottom of page?

[tsangcn]

Hello,

 

I want to print several sales order at a time. I have create a jasperreport group by sales order number with "print on new page" and "reset page number". No page footer is needed by at the last page of "each order", I want the group foot to be print at the bottom of a page. Now the group footer is print at the end of details band. I have tried many ways but not success. How can I do that?

 

Thanks
