You control the margins by using SectionTop, SectionLeft, SectionRight & SectionBottom.
So you can try and put PrintFooter() under this line:

SectionBottom := 10;

You can set the margins as follows:

with BaseReport do begin
  Margin Left := 0.5;
  Margin Right := 0.5;
  Margin Top := 0.5;
  Margin Bottom := 0.5;
  Orientation := poPortrait;
end;

The measures are inches. Set the ruler to inches then when you set SectionBottom to 10 then the bottom of the page will be at 10 on that ruler. So it did not work out for you because 30 is out of the page's border. The maximum you can set is 11.

Try this way:
function TMainForm.LibRvSystemPrintPage(Sender: TObject;
  var PageNum: Integer): Boolean;
begin
   With Sender as TBaseReport do
    begin
      SectionTop := 1.5;
      SectionBottom := 10;
      PrintFooter('Page : '+ IntToStr(CurrentPage), pjLeft);
    end
end;

You can find your margins from RpDev.Waste property
Left := RpDev.Waste.Left / RpDev.XDPI;
    Top := RpDev.Waste.Top / RpDev.YDPI;
    Right := RpDev.Waste.Right / RpDev.XDPI;
    Bottom := RpDev.Waste.Bottom / RpDev.YDPI;

Please could you use the event OnPrint:
function TMainForm.LibRvSystemPrint(Sender: TObject;
  var PageNum: Integer): Boolean;
begin
   With Sender as TBaseReport do
    begin
      SectionTop := 2 ;
      SectionBottom  := 10.5;
      PrintFooter('Page : '+ IntToStr(CurrentPage), pjCenter);
    end
end;

Open in new window


Orientation will not work in the Print events. If you want to change the orientation, set it either at the object inspector or using the TRvSystem property (RvSystem.SystemPrinter.Orientation) but the most important thing is to set it before executing the report:
procedure TForm1.Button1Click(Sender: TObject);
begin
  RvSystem1.SystemPrinter.Orientation := poLandScape;
  RvSystem1.Execute;
end;

Click on the RvSystem and from the object inspector go to SystemPrinter and set the property Units to unMM.

By code:
RvSystem1.SystemPrinter.Units := unMM;
