> Turns out the standard printer is very limiting in terms of how many bits of data you can fit into paper if you want to read it reliably.

What print technology were you using? (Inklet, laser, etc.)

Tested on both ink and laser. There is a small introduction of error even with the laser printer and you have another error introduced by scanning. That limits how small the QR codes can be. Paper+QR codes are feasible only for very small files.
