I got the solution:

function set_barcode($code) {    $this->load->library('zend');    $this->zend->load('Zend/Barcode');    $file = Zend_Barcode::draw('code128', 'image', array('text' => $code), array());    $code = time().$code;    $store_image = imagepng($file,"../barcode/{$code}.png");    return $code.'.png'; } 

store the image using imgepng function.
it will store the bar code image in barcode folder.
