I have managed to find zero-days in my Canon with some effort over the last few weeks, me and a cheap model, well it was never really that hard, but I feel like it has given me more time.
I am considering reverse engineering the entire thing, I honestly don't know if that's worth it given I can connect an rpi to the system and get everything done via my own app now.
And keeping printer off of wifi networks was the best decision I ever made imho. Either way printers suck, but I like them so much as a technology, converting digital to physical is such a great thing.
It's really surprising we have open source 3D printers with way more complex kinematics, parts, etc than a printer but we don't have a traditional open source printer despite printers existing since the 70s.

It's been on HN this year to my recollection. Maybe it has some closed firmware or something that means it's not "open" for you?
Not that surprising.
