----------SOLVED----------

Hello!

I want to put a base64 QR code in my POS Receipt with some of the order information.

I already got to inherit and edit the POS Receipt.

But I can't send the QR code to the Receipt with "export_for_printing()" because I need to make the function async in order to generate the QR code.

Everytime I try to make it async, I get "TypeError: ctx.receipt.company is undefined", because maybe another function which is not async is trying to get the data.

Do you have any idea that could help me?

Thanks!
