Code

public function render(array $entities, $use_default_css = TRUE, $optimize_css = TRUE) {
  $build['#attached']['library'] = [];

  // Inject some generic CSS across all templates.
  if ($use_default_css) {
    $build['#attached']['library'][] = 'entity_print/default';
  }
  $build['#attached']['library'] = array_merge($this->assetCollector
    ->getCssLibraries($entities), $build['#attached']['library']);

  // This keeps BC for the CSS alter event which used to provide a render
  // array but now passes a list of libraries. So, if users of the API have
  // treated it like a render array, we move the libraries into the correct
  // place.
  foreach ($build['#attached']['library'] as $key => $library) {
    if ($key === '#attached') {
      $build['#attached']['library'] = array_merge($build['#attached']['library'], $library['library']);
      unset($build['#attached']['library'][$key]);
    }
  }
  $css_assets = $this->assetResolver
    ->getCssAssets(AttachedAssets::createFromRenderArray($build), $optimize_css);
