Printing Footer In Reports

hi,
I am using vb.net 2005 and sql server 2005 express edition.
I have used reports (*.rdlc) to print invoice. The invoice format is as follows:
'**********************************************************************************
Company Name

Party Name Invoice No.
Date

Item No. Description Qty Rate Amount
1
2
3

Taxes and Duties applicable

Amount In Words

For Company Name

'**********************************************************************************

All the data is placed in body section of report using different DataTable dataregions.
This is done as Taxes and Duties have multiple Rows and columns
but the location of printing of Taxes & duties Table on paper always changes depending on the no. of items in the invoice
this does not match with the pre printed stationery used for invoice printing.

How do i print the taxes & duties and all details below the ItemDetails Table always at the same location independent of
the no. of items in the invoice?
