I finally find the answer. It is possible if the document is stored in the server side end then you make the action of allowing the user to download it. The following code explain it:
$docName = 'document.doc';
$docPath = 'path/inThe/server/';
$fullName= $docPath.$docName;
$objWriter->save($fullName);
$this->downloadTimeSheetFile($docName,$docPath);
header('Content-type: application/doc');
header('Content-Disposition: attachment; filename="'.$docName.'"');
readfile($fullName);
Hope somebody can use it! :)
