Is this compatible with libfprint-2-dev?

On Ubuntu 20.04, the only package avaible to install is libfprint-2-2 and libfprint-2-dev. Are those supposed to be compatible? Because I would assume not since npm i node-fprint fails.

No. It is currently only compatible with libfprint0.
If you have fun, just update the code so it works with libfprint-2 ... :)

Or manually compile libfprint and link against this installation
