QR Code not showing in PDF when downloaded

Hello, When i am printing to pdf, in google chrome the QR code shows correctly. But when we download and open via adobe or even microsoft edge, the QR code is not shown. Can anyone help what could be the reason for this?

I generated a PDF document with a QR code, which is placed both in the table and simply in the body of the document:
- For Tcpdf in Chrome, Firefox, Edge and even PhotoShop - it's displayed successfully everywhere.
- For Dompdf in Chrome, Firefox, Edge - it's displayed successfully everywhere. For PhotoShop - the display is either missing or distorted. I don't know if this is worth paying attention to, because PhotoShop is not a means of viewing PDF files.
