Hi,

I need to know how I can set a printers properties to be default at Tractor Feed.
Every time I use my printer the paper source resets itself to Manual Feed. I have disabled Manual and Sheet Feeder in the printer properties but this doesnt work.

When I select my printer using the printerdialog I need the default paper source to be Tractor and paper output to be 8 1/2 x 11.

Is there any way I can set this in code? Im using Delphi 5 Prof and the dialog is TPrinterDialog

Any suggestions would be great,
Thanks

Havent tried this yet, but I found the sample on the net and it looks like it could work. Try setting the different properties of pDMode:

//-------------------------------------------------------------------------

procedure TForm1.Button2Click(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
      pDMode^.dmPaperSize:=DMPAPER_LEGAL;
      { There are many more parameters here you can try, and other properties like pDMode^.dmDefaultSource
      for example. }
      GlobalUnlock(hDMode);
    end;
    GlobalFree(hDMode);
  end;
end;

//------------------------------------------------------------------------

If all else fails, then maybe you could try using SendKeys on the dialog?
 
Depends on if you are able to get hold of the right window. Takes some "trial and error programming", but sometimes it does the trick. See http://www.cbuilder.ru/faqs/faqd_en/16500.html http://www.209software.com/Books/p4dp/sendkeys.html for a sample.
