Variable header in ALV

Question

Hi all,
I want to print variable text in the top-of-page in the ALV.
Suppose, I am making customer wise sales report.
A new page is triggered when customer changes. I have done this.
I want to print customer name and code in the top of page  whenever the customer changes. I have done coding for this like I have made list header which changes when the customer changes.It is working well when the user sees the report output on the screen but when he prints it , the headers are not printed.
Please give me the solution of this problem.
Thnaks and Regards
