I would like to help getting the plugin translatable

If so, here it is:

Note to others: This is a quickfix until developer adds this to the plugin himself:

1. Add the following to index.php:

   function load_textdomain_for_woocommerce_pdf_invoices() {
   	load_plugin_textdomain( 'woocommerce-pdf-invoices', false, dirname( plugin_basename( __FILE__ ) ) . '/lang/' );
   }
   add_action('init', 'load_textdomain_for_woocommerce_pdf_invoices');

2. and download the po file from: https://www.bonusboek.nl/woocommerce-pdf-invoices.po
3. Create /wp-content/plugins/woocommerce-pdf-invoices/lang/
4. upload your translation to woocommerce-pdf-invoices-[LANGCODE].mo into /wp-content/plugins/woocommerce-pdf-invoices/lang/

Please try my new version 1.0.2. It is translation ready.
Thank you for your advice!
Would be so kind to rate my plugin with 5 stars? ??

woocommerce-pdf-invoices-it_IT mo and po uploaded in lang folder.
However, the PDF is still in english.

Noticed this too. When adding code from frekel in index.php it works.

In the next update (coming soon) all fixed it. ??
Almost ready.
