Is possible convert directly HTML into a pdf file using Zend_Pdf?, if so, How can I do that?
Zend_PDF
isn't able to generate PDF based on HTML. But you can render view and use other library for convert it to PDF. I've done such thing with TCPDF. Little code snippet below:
//SomeController.php
$this->_helper->layout->disableLayout();
//set content for view here
// create new PDF document
require_once('tcpdf/tcpdf.php');
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
//whole TCPDF's settings goes here
$htmlcontent = $this->view->render('recipe/topdf.phtml');
// output the HTML content
$pdf->writeHTML($htmlcontent, true, 0, true, 0);
$pdf->lastPage();
$pdf->Output("pdf-name.pdf", 'D');
