Hello, my name is Angel and I have a problem. I don't know how I can print an ASCII file in Delphi after press a button. I don't want use TPrinter component. I like that result was identical that I wrote in MS-DOS 'print autoexec.bat'.

Thanks.

 Why don't you want to use the TPrinter? It is the easiest way and any other technique will involve doing much the same kind of thing, but in a more complicated fashion. Explain why you can't use TPrinter and I'll try to help.

This will do for 50 pt:

procedure TMainForm.Button12Click(Sender: TObject);
var
  t, lpt: TextFile;
  line  : string;
begin
  if OpenDialog.Execute then try
    AssignFile(t, OpenDialog.Filename);
    AssignFile(lpt, 'LPT1');
    FileMode := 0;
    Reset(t);
    Rewrite(lpt);
    while not EOF(t) do begin
      ReadLn(t, line);
      WriteLn(lpt, line);
    end;
    Write(lpt, #4); // end of transmission
    CloseFile(lpt);
  except
    // trap errors here
  end;
end;

-= or simply =-

procedure TMainForm.Button13Click(Sender: TObject);
begin
  Winexec('cmd /c print main.txt', SW_HIDE);
end;
