Hi,

I have the following code wich does that but in another way. Pressing button1 will fill the listbox with the names of the printers. Select one of the printers and press button2. The richedit will be filled with the names and sizes (in thousants of mm) at once. I'm sure you can adapt it for your needs.

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

type
  TForm1 = class(TForm)
    re: TRichEdit;
    lb: TListBox;
    Button1: TButton;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

uses Printers, WinSpool;

// fill the lb with printer names
procedure TForm1.Button1Click(Sender: TObject);
begin
  lb.Items.Text := Printer.Printers.Text;
end;

// get printer forms (name an size)
procedure TForm1.Button2Click(Sender: TObject);
var
  PHD         : THandle;
  info        : array [0..10000] of TFormInfo1;
  pcbNeeded   : DWORD;
  pcReturned  : DWORD;
  i: integer;
begin
 if OpenPrinter(PChar(lb.Items[lb.ItemIndex]), PHD, nil) then begin // open the printer
    EnumForms(PHD, 1, @Info, SizeOf(Info), pcbNeeded, pcReturned); // get the info
    for i := 0 to 10000 do begin
      if Info[i].pName = nil then exit;
      re.Lines.Add(Info[i].pName); // name of the form
      re.Lines.Add(IntToStr(Info[i].Size.cx)); // width
      re.Lines.Add(IntToStr(Info[i].Size.cy)); // height
      re.Lines.Add('');
    end;
    ClosePrinter(PHD);
  end else ShowMessage('Cannot open the printer');
end;

end.


Regards, Geo

This is how to get printer paper dimensions

  PrintersetupDialog1.Execute;
  Printer.PrinterIndex;
  Edit3.Text := IntToStr(GetDeviceCaps(Printer.Handle, HORZSIZE));
  Edit4.Text := IntToStr(GetDeviceCaps(Printer.Handle,VERTSIZE));

 

by: mokulePosted on 2006-09-05 at 16:39:37ID: 17459799

Should be
Printer.PrinterIndex := -1;
to set default printer.
received dimensions are in mm
