Be careful where you print these. Most full-featured printer/copier/scanner devices found in office environments can store print job data on the HD where service technicians can access it.

For extra fun, the printer is likely either on the network or has bluetooth. Age-old poorly written embedded computer with network services written in C is the industry standard. It's totally plausible to break in and steal previously-printed data.
I'll use my own printer, and after it dies on me, I will give it the Office Space treatment ;)
There's always paper-age[0] for those who want to add symmetric encryption (via age) to their qr-encoded secrets! ;)
