{$R *.DFM}

procedure TForm1.EndeBtnClick(Sender: TObject);
begin
  close;
end;

procedure TForm1.BitBtn1Click(Sender: TObject);
var
  aWindowState: TWindowState;
begin
  aWindowState:= WindowState;
  try
    PrintFrm:= TPrintFrm.Create(self);
    PrintFrm.Init(Grid1);
    PrintFrm.QuickRep1.Preview;
  finally
    if PrintFrm <> nil then
      PrintFrm.Free;
    WindowState:= aWindowState;
  end;
end;

procedure TForm1.FormShow(Sender: TObject);
var
  aRow: ShortInt;
begin
  with Grid1 do begin
    Colwidths[0]:= 20;
    Colwidths[1]:= 80;
    Colwidths[2]:= 80;
    Colwidths[3]:= 80;
    Colwidths[4]:= 80;
    Cells[0,0]:= 'lfdNr';
    Cells[1,0]:= 'Art_Sorte';
    Cells[2,0]:= 'Art_Gruppe';
    Cells[3,0]:= 'Inhalt';
    Cells[4,0]:= 'Preis';
    for aRow:= 1 to RowCount-1 do begin
      Cells[0,aRow]:= IntToStr(aRow);
      Cells[1,aRow]:= 'Artikel ' + IntToStr(10000 + aRow);
      if (aRow mod 2) = 0 then
        Cells[2,aRow]:= 'Wein'
      else
        Cells[2,aRow]:= 'Sekt';
      Cells[3,aRow]:= '0,75 l';
      Cells[4,aRow]:= FloatToStr(4.20 + aRow);
    end;
  end;
end;

end;

procedure TPrintFrm.FormClose(Sender: TObject; var Action: TCloseAction);

end.

damit sollte dein stringgrid problemlos ausgedruckt werden
