Changing printer paper size

Hi all,
I need to change printer paper size at rintime (and printer resolution too).
TPrinter object hasn't properties (as far as I know) for maintaining them. I do not want to use standard printer dialog for this prupose. Is there some OTHER way to do it?

Thanks at advantage.
Jo.

I had similar problems with the printers unit keeping many goodies private on delphi 2, needed a quick solution and solved the problem by duplicating the printers.pas unit to myprinters.pas and changing it.

When migrating to delphi 3, I did the same (duplicated and changed the printers unit).

This was *not* an elegant solution to say the least, but it was quick and works.

try this:

unit Unit1;

interface

uses
  Windows, Messages,Printers, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

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.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.Font.Name := 'Courier New';      Printer.Canvas.Font.Size := 10;
Printer.Canvas.Font.Color:=ClRed;
 Printer.Canvas.TextOut(100,100, 'Test 1');  Printer.EndDoc;
end;
end.


i advise have a look in windows.pas for more paper sizes under:
{ paper selections } heading.there is quite a lot.
