You can help to TRVPrint to print inserted components in OnPrintComponent

event.

Below is the (simplified) example for TLabel:

procedure TForm3.RVPrint1PrintComponent(Sender: TCustomRVPrint;

  PrintMe: TControl; var ComponentImage: TBitmap);

var DTOption: Integer;

    r: TRect;

const HAlignments: array[TAlignment] of Integer =

(DT_LEFT,DT_RIGHT,DT_CENTER);

      VAlignments: array[TTextLayout] of Integer = (DT_TOP, DT_VCENTER,

DT_BOTTOM);

begin

  if PrintMe is TLabel then begin

    ComponentImage := TBitmap.Create;

    ComponentImage.Height := PrintMe.Height;

    ComponentImage.Width  := PrintMe.Width;

    r := Rect(0,0,PrintMe.Width,PrintMe.Height);

    if not TLabel(PrintMe).Transparent then begin

      ComponentImage.Canvas.Brush.Color := TLabel(PrintMe).Color;

      ComponentImage.Canvas.FillRect(r);

    end;

    ComponentImage.Canvas.Font := TLabel(PrintMe).Font;

    DTOption := DT_SINGLELINE or

      HAlignments[TLabel(PrintMe).Alignment] or

VAlignments[TLabel(PrintMe).Layout];

    if not TLabel(PrintMe).ShowAccelChar then

      DTOption := DTOption or DT_NOPREFIX;

    if TLabel(PrintMe).WordWrap then

      DTOption := DTOption or DT_WORDBREAK;

    DrawText(ComponentImage.Canvas.Handle,

PChar(TLabel(PrintMe).Caption), -1, r, DTOption);

  end;

end;
