Hi @ellipee,
do you've added the configuration on the config/autoload?

Please take a look at: https://github.com/mvlabs/MvlabsSnappy#configuration

I recommend to install the module via composer. The module has dependencies, and manually could only work by installing the dependencies manually too.

I hope this helps to clarify.

Thank you @drigani for you quick response.
i did install everything using composer and i copied the configuration on the config/autoload with the settings as follows.

array( 'pdf' => array( 'binary' => 'websites/ice/vendor/google/wkhtmltopdf-amd64/wkhtmltopdf-amd64', 'options' => array(), ), 'image' => array( 'binary' => '/usr/local/bin/wkhtmltoimage', 'options' => array(), ) ) ); and inside my controller public function generatepdfAction() { $entityManager = $this->getServiceLocator()->get('doctrine.entitymanager.orm_default'); ``` $id = (int) $this->params()->fromRoute('id', 0); // var_dump($id) if (!$id) { return $this->redirect()->toRoute('staff', array('controller'=>'staff','action' => 'view')); } $staff = $entityManager->getRepository('Admin\Entity\Staff')->findOneBy(array('id' => $id)); if (!$staff) { return $this->redirect()->toRoute('staff', array('controller'=>'staff', 'action'=>'view')); } $viewRenderer = $this->serviceLocator->get('view_manager')->getRenderer(); $view = new ViewModel(array('staff'=>$staff)); $view->setTemplate('Admin/Staff/viewfull'); // path to phtml file under view folder $view->setTerminal(true); $htmlOutput = $viewRenderer->render($view); $output = $this->serviceLocator->get('mvlabssnappy.pdf.service')->getOutputFromHtml($htmlOutput); $response = $this->getResponse(); $headers = $response->getHeaders(); $headers->addHeaderLine('Content-Type', 'application/pdf'); $headers->addHeaderLine('Content-Disposition', "attachment; filename=\"export-" . $now->format('d-m-Y H:i:s') . ".pdf\""); $response->setContent($output); return $response; ``` } i got this error ``` The file 'C:\Windows\TEMP\knp_snappy55a80b65a18d25.83605966.pdf' was not created (command: websites/ice/vendor/google/wkhtmltopdf-amd64/wkhtmltopdf-amd64 --lowquality "C:\Windows\TEMP\knp_snappy55a80b65a15be5.55916267.html" "C:\Windows\TEMP\knp_snappy55a80b65a18d25.83605966.pdf") ```

hi @ellipee,
first of all make sure that running the command from terminal works. You can try in the command line:

websites/ice/vendor/google/wkhtmltopdf-amd64/wkhtmltopdf-amd64 --lowquality http://google.com google.pdf

hi @drigani
I'm with the same issue, and for me, running the command from terminal, it works. I have tried to show direct to browser like in example and also get output and save to a file, but nothing worked.

• I have tried on Windows, with standart instalation, and on Linux via binary file downloaded with composer at the repository h4cc/wkhtmltopdf-amd64
