用delphi写的，可以设置默认打印机，麻烦详细写出。该引用什么单元等等

procedure TForm1.Button1Click(Sender: TObject);
var
WinIni : TIniFile;
WinIniFileName : array[0..MAX_PATH] of char;
s : array[0..64] of char;

begin
GetWindowsDirectory(WinIniFileName, sizeof(WinIniFileName));
StrCat(WinIniFileName, '\win.ini');
WinIni := TIniFile.Create(WinIniFileName);
try
WinIni.WriteString('windows',
'device',
'HP LaserJet Series II,HPPCL,LPT1:');
finally
WinIni.Free;
end;

StrCopy(S, 'windows');
SendMessage(HWND_BROADCAST, WM_WININICHANGE, 0, LongInt(@S));
end;
