Hola principiante22, para imprimir directamente debes añadir los componentes RvSystem, RvRenderPrinter, tu RvProject->Engine->RvSystem

Código Delphi [-]
 With RvSystem do
  begin
   DefaultDest := rdPrinter;
   RenderObject := RvRenderPrinter;
   DoNativeOutput := False;
   SystemSetups := SystemSetups - [ssAllowSetup];
  end;

 With RvProject do
  begin
   ProjectFile := 'reporte.rav';
   Open;
   Execute;
  end;

Saluditos
