Tool for splitting and printing data in QR codes

qr-splitter

This is a tool and Python library to take a (possibly large) block of data and print that data onto one (or more) pages of QR codes.

It is useful to take e.g. a PSBT and print it for offline signing by a HodlerGlacier quarantined laptop.

How do I use it?

You need at least Python 3.7.

Run make to build a python venv; source venv/bin/activate to set your PATH.

./qr_split.py --title="PSBT" my.psbt > my.html
firefox my.html

Then Ctrl-P in Firefox to print!
