I am not aware of any receipt printers using lasers - thermal printers have an array of resistors that get hot when necessary. I know how a laser printer works and it is hard to explain in 12 or so words. Inkjets are way easier, you can just say “squirt squirt oops”. Anyway…
Time travel is a prerequisite but don’t worry, you can just
from __future__ import antigravity
Laser printers more accurately “bake paper so that number powder sticks to it”
I wonder if there is a notification ad blocker with community-submittted sets of regex patterns that root users can use.

You are right, QR codes are very easy to decode if you have them raw, even the C64 should do it in a few seconds, maybe a minute for one of those 22 giant ones. The hard part is image processing when decoding a camera picture - and that can be done on the C64 too if it has enough time and some external memory (or disks for virtual memory). People have even emulated a 32-bit RISC processor on the poor thing, and made it boot Linux.
