Good day I am from Venezuela friends got into this world alone and cakephp me happy but I have a problem ayenme please.

I CakePdf use the plugin and have problems with a pdf.

this is my code in the controller

public function reporte_factura_pdf($marca, $referencia, $fecha1, $fecha2) {

//public function reporte_factura_pdf() {

    $this->loadModel('Norma', 'RequestHandler');
    $this->loadModel('Referencia', 'RequestHandler');
    $this->loadModel('Articulo', 'RequestHandler');
    $this->loadModel('ArticulosFacturas', 'RequestHandler');
    $this->loadModel('Facturas', 'RequestHandler');


//$facturas=$this->params->params['array_fac'];        

$options[] = array(
    'and' => array(
                    array('fecha <= ' => $fecha2,
                          'fecha >= ' => $fecha1
                         )));

        
    $this->pdfConfig = array(
        'download' => true,
        'filename' => 'user_' . 18 .'.pdf'
    );


    $array_fac=$this->Factura->find('all', array('recursive' => -1,'fields' => array('Factura.id','Factura.fecha', 'Articulo.norma_id', 'Articulo.referencia_id','Art_Fac.cantidad', 'Marca.descripcion', 'Referencia.nombre',), 'joins' => array(

        
        array(
        'table' => 'articulos',
        'alias' => 'Articulo',
        'type' => 'INNER'
       ),


        array(
        'table' => 'normas',
        'alias' => 'Marca',
        'type' => 'INNER',
        'conditions' => array(
            'Marca.id = Articulo.norma_id'
        )),

        array(
        'table' => 'referencias',
        'alias' => 'Referencia',
        'type' => 'INNER',
        'conditions' => array(
            'Referencia.id = Articulo.referencia_id'
        )),

         array(
        'table' => 'articulos_facturas',
        'alias' => 'Art_Fac',
        'type' => 'INNER',
        'conditions' => array(
        
            'Art_Fac.articulo_id = Articulo.id',
             'Art_Fac.factura_id = Factura.id'


        ))
    ), 'conditions' => $options));


    

   $this->set('facturas', $array_fac);    
/*
$this->set('marca', $marca);
$this->set('referencia', $referencia);
$this->set('fecha1', $fecha1);
$this->set('fecha2', $fecha2);
*/

}

And my view has only one debug ($facturas).
