Barcode Generator and Printing Integration

Yes you can.

If you want to do it on client side, here are a couple of discussions around using an API service to generate QR Code:

If you know some other barcode generator library that works on client side, you can use JS to integrate that. There is also now custom client side component capability in Wappler, which would result in a better UX - but it has a learning curve of its own.

Lastly, you can create custom extensions on server side, where you can use any npm/php library for generating the barcode. These are relatively simpler to build and use than client side extensions.

I could not find any extension for this in community, but it should not be that difficult to build.
I haven’t personally had a use case for this yet.
