<?php

namespace Drupal\pdf_generator\Controller;

use Dompdf\Dompdf;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\ResponseHeaderBag;

class PDFGeneratorController {
    public function generatePDF() {
        $dompdf = new Dompdf();
        $html = '
            <h1 style="color:blue; text-align:center;">Drupal PDF Generation</h1>
            <p>This is a sample PDF generated in Drupal using DomPDF.</p>
        ';
        $dompdf->loadHtml($html);
        $dompdf->setPaper('A4', 'portrait');
        $dompdf->render();
        
        $response = new Response($dompdf->output());
        $response->headers->set('Content-Type', 'application/pdf');
        $response->headers->set('Content-Disposition', ResponseHeaderBag::DISPOSITION_ATTACHMENT, 'sample.pdf');

        return $response;
    }
}

pdf_generator.download:
  path: '/generate-pdf'
  defaults:
    _controller: 'Drupal\pdf_generator\Controller\PDFGeneratorController::generatePDF'
    _title: 'Download PDF'
  requirements:
    _permission: 'access content'

✅ Step 7: Enable the Module
