D8 : save a pdf using entity_print print builder service and display it as link

save_pdf_entity_print.php

<?php

use Drupal\Core\Url;
      
$entities = [node_object];
$scheme = 'public';
$filename = 'something.pdf';
$export_type = 'pdf';

/* @var \Drupal\entity_print\PrintBuilder $print_builder */
$print_builder = \Drupal::service('entity_print.print_builder');
$print_engine = \Drupal::service('plugin.manager.entity_print.print_engine');
$engine = $print_engine->createSelectedInstance($export_type);

$file_uri = $print_builder->savePrintable($entities,$engine,$scheme,$filename, TRUE);

//$pdf_link is Url object
$pdf_link = Url::fromUi(file_create_url($file_uri));

Thank you
