Bitrix24 tFPDF Header and Footer?

Question

PHP

Hello, help me figure it out)
CMS: Bitrix 24 boxed version.
Module: Sale Payment (document generation) I use the tFPDF
class to generate a pdf document. I extend the functionality and create an instance of the class. Overridden the Header and Footer methods. When called

$pdf->Header();
$pdf->Footer();

The code returns a result.
Question: Is it possible to make the header and footer on every page? How are the headers and footers of Word?
I didn't find the answer on the Internet, but maybe I'm missing something.
Thanks in advance!
