The following should get you going, there is 3 things you have to change, your renderer, your method to render the barcode to the pdf and for some obscure reason, you have to include a font to your Zend_Barcode or you will get an error
$pdf = new Zend_Pdf();
// Your font (path might differ)
Zend_Barcode::setBarcodeFont(APPLICATION_PATH . '\..\data\resources\fonts\arial.ttf');
$config = new Zend_Config(
array(
'barcode' => 'code39',
'barcodeParams' => array('text' => '11020109'),
'renderer' => 'pdf', // here is your new renderer
'rendererParams' => array(), // you can define position offset here
)
);
$pdfWithBarcode = Zend_Barcode::factory($config)->setResource($pdf)->draw(); // your new barcode renderer is defined here, from now on to add things to your pdf you need to use the new variable ($pdfWithBarcode)
// Save your pdf (path might differ)
$pdfWithBarcode->save(APPLICATION_PATH . '\..\data\testBarcode.pdf');
