Barcode not appearing in PDF

[JonesNavela]

Hi, I noticed that when I transform my html document to PDF, the barcode doesn't appear. Only the barcode value...

Hi! This is because barcode is drawn on Canvas html element. What you can do is convert Canvas drawing to image before printing: https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toDataURL.
Also, you can catch printing event with onBeforePrint: https://developer.mozilla.org/en-US/docs/Web/API/Window/beforeprint_event
