As you have noted, a QR code is not a "normal" barcode. It is a 2-dimensional barcode using one of four possible data encoding schemes. The on/off bit pattern is laid out in a serpentine pattern and utilizes one of four error correction algorithms . There are (currently) 40 different versions/resolutions supported, so you can see that creating one requires some fairly sophisticated software... generating a QR code is a much more complex process than substituting a simple series of stripes for each character as is typically done for a traditional barcode.

There are commercial software products you can purchase to generate QR code images, or there are Web REST API's you can use (examples obtainable by searching this Q&A forum), but since PB version 9 lacks the ability to interface with REST API's.
