Unfortunately, it's not possible to have the footer fixed at the bottom of the page as it’s not technically possible when working with HTML and browser printing.
The issue is that browsers don't have a concept of "pages", and so, there is no way to reliably put information at the footer of pages being printed through the browser; HTML makes it impossible to create a sticky printed footer at the bottom of the pages.
Therefore, the templates will respond depending on how big the order is; so it will adjust appropriately, and it's expected for it to get bumped down as the content above gets longer.
Note: For big orders, the footer will always be printed at the bottom of the last page only as it is not possible to print the footer on all printed pages.
