Force papersize when printing QuickReport

Hi Experts,

I'm having a nasty problem with QuickReport reports in my application:

I designed all reports with papersize A4. So, the Page.Papersize property of all QuickReport reports shows A4. So far, no problem.

Now, in my company, there are several HP DeskJet printers which seems not to use this QuickReport papersize. With laserjet printers there's no problem, even if the laserjet driver has i.e. papersize Letter selected, the reports is printed as A4. That's OK.
Some DeskJets however seem to use their own current papersize setting. Even if the user selects A4 in the printer dialog (that is launched by a QuickReport.Printersetup method), the report is printed with Letter papersize on the DeskJet. Therefore a part of the report is missing !
When I print i.e. using MS-Word on the DeskJet, there's no problem. In Word's print dialog you can change the size Letter to A4, and the MS-Word print comes out correct.

Because all reports are A4 reports (and all printers in my company have A4 paper loaded), I would like to force the printer papersize before every print to A4, but I don't know how to do this.
I tried QuickReport.Page.Papersize := A4 and QuickReport.PrinterSettings.Papersize := A4, but the compiler does'nt accept this.

So, my question is: how can I force the papersize of the QuickReport print to A4, and overrule all settings of the driver? The QuickRep.PrinterSetup method (where you also can select a papersize) does'nt seem to have effect on some HP DeskJets.
Or is there perhaps another way to get rid of this problem?

Hope someone can help.

Thanks,
JDN

Maybe you must set the size through code :

procedure TForm1.Button1Click(Sender: TObject);
var
  Device : array[0..255] of char;
  Driver : array[0..255] of char;
  Port   : array[0..255] of char;
  hDMode : THandle;
  PDMode : PDEVMODE;
 
begin
  Printer.PrinterIndex := Printer.PrinterIndex;
  Printer.GetPrinter(Device, Driver, Port, hDMode);
  if hDMode <> 0 then begin
    pDMode := GlobalLock(hDMode);
    if pDMode <> nil then begin

     {Set to legal}
      pDMode^.dmFields := pDMode^.dmFields or dm_PaperSize;
      pDMode^.dmPaperSize := DMPAPER_LEGAL;

     {Set to custom size}
      pDMode^.dmFields := pDMode^.dmFields or
                          DM_PAPERSIZE or
                          DM_PAPERWIDTH or
                          DM_PAPERLENGTH;
      pDMode^.dmPaperSize := DMPAPER_USER;
      pDMode^.dmPaperWidth := 100 {SomeValueInTenthsOfAMillimeter};
      pDMode^.dmPaperLength := 100 {SomeValueInTenthsOfAMillimeter};

     {Set the bin to use}
      pDMode^.dmFields := pDMode^.dmFields or DMBIN_MANUAL;
      pDMode^.dmDefaultSource := DMBIN_MANUAL;

      GlobalUnlock(hDMode);
    end;
  end;
  Printer.PrinterIndex := Printer.PrinterIndex;
  Printer.BeginDoc;
  Printer.Canvas.TextOut(100,100, 'Test 1');
  Printer.EndDoc;
end;
