        $this->load->library('zend');
        $this->zend->load('Zend/Barcode');

        $barcodeOptions = array('text' => 'ZEND-FRAMEWORK');
        $rendererOptions = array('imageType'          =>'png', 
                                 'horizontalPosition' => 'center', 
                                 'verticalPosition'   => 'middle');

thanks for using my library..

Check this issue : https://github.com/desta88/Codeigniter-Barcode-Generator-Zend-Library/issues/1 (The EXT constant has been removed on CI 3)

Just change constant, from EXT to '.php', in your libraries/Zend.php

Or

Download here, I've been updated from this issue : http://api.mdesain.com/Codeigniter-Barcode-Generator-Zend-Library/barcode.zip

Using return is incorrect. You should be able to just do:

Zend_Barcode::factory('code39', 'image', $barcodeOptions, $rendererOptions)->render();

And this should display the image on screen.
