Apple allows people to print out their recovery key when enabling two factor.

Taking the assumption that the local spooler may not do a great job of protecting, secure erasing, and eliminating traces of the printout; where on the file system would the spool remnants be?

Outside of OS-specific locations, perhaps there are browser caches and vendor-print driver specific locations where this sensitive data can be stored without the user knowing.

This question is not just applicable to OSX two factor security, but also, anytime someone wants to print something securely on OSX.
