well lazreport is band based so adding a page footer band will print everytthing you add to it at the bottom of the page by default it does not matter where it is its position at design time.
EDIT:
Tested it on lazarus 1.0.10 and it has the same problem the workaround is simple though just restore the designer from the maximized state and resize the window until the scrollbars are visible and remaximize it. Everything should work after that.
