You should run this command to add this extension into your composer.json.

composer require dompdf/dompdf

OR add this line in your composer.json require section and run composer update :

"require": {
    "dompdf/dompdf": "^0.7.0"
},

And then in your view access this way.

// reference the Dompdf namespace
use Dompdf\Dompdf;

// instantiate and use the dompdf class
$dompdf = new Dompdf();
$dompdf->loadHtml('hello world');

// (Optional) Setup the paper size and orientation
$dompdf->setPaper('A4', 'landscape');

// Render the HTML as PDF
$dompdf->render();

// Output the generated PDF to Browser
$dompdf->stream();
