Get Default Printer

Hi Experts,

Can anybody show me code line(s) how to get the default printer in delphi 6?
Say provided a form and a button, when the user clicks on it, it will
display the default printer (on the machine where this program is running)
together with the default paper size and paper length.
Note that from time to time, the default printer may not be the one locally attached on this computer. It might be from another machine/computer.

TIA,
yorge

Very easy,

uses
  printers;

....

begin
  ShowMessage(Printer.Printers[Printer.PrinterIndex]);
end;

to know the paper size use Printer.Paperwidth and Paperheight properties.

more precisely,
Printer.PrinterIndex := -1; // sets the printer to default; -1 for default printer
then
ShowMessage(Printer.Printers[Printer.PrinterIndex]);
...

Thanks atul. I have found that without first setting the default printer a reference to Printer.PrinterIndex can cause a runtime crash deep in ntdll.dll. Without setting the PrinterIndex to -1 my code would fail on the line:

If (Printer.PrinterIndex > 0) Then

My Delphi code to get the default printer name now looks like this:

Function getDefaultPrinterName(): String;
Begin
   Printer.PrinterIndex := -1;     // set to default
   If (Printer.PrinterIndex > 0) Then
      Try
         Result := Printer.Printers[Printer.PrinterIndex]
      Except
         Result := 'Unknown'
      End
   else
      Result := 'Unknown'
End;
