En el Form coloca un RvProject, un RvNDRWriter y los enlazas con la propiedad RvProject.Engine un RvRenderPDF y un RvRenderPrinter.

Para imprimir:

Código Delphi [-]
procedure TForm1.ImprimirRaveReport;
begin
  NDRStream := TMemoryStream.Create;
  try
    RvProject1.open;
    begin
    RvProject1.SaveToStream(NDRStream);
    RvNDRWriter1.Stream:=NDRStream;
    RvProject1.Execute;
    RvRenderPrinter1.Render(NDRStream);
    RvProject1.close;
  finally
    NDRStream.Free;
  end;
end;

Para crear un PDF:

Código Delphi [-]
procedure TForm1.CrearFicherosPDF;
var
  NDRStream:  TMemoryStream;
begin
  NDRStream := TMemoryStream.Create;
  Try
    RvProject1.open;
    mFilename1 := 'C:\Pba.Pdf';
    RvProject1.SelectReport('Report1,true);
    RvProject1.SaveToStream(NDRStream);
    RvNDRWriter1.Stream:=NDRStream;
    RvProject1.Execute;
    RvRenderPDF1.PrintRender(NDRStream,mFilename1);
  finally
    NDRStream.Free;
  end;
  RvProject1.close;
end;
