I love modern printers.
We have a super fancy one in work that requires one to log in (or fob in with an NFC-style tag), to enable access to their own virtual print queue or printer services.
Weirdly, if it doesn't shut down correctly (software failure, power cut, flicked at the wall switch etc), it reboots but with some quirks like not enabling the 10 second auto logout.
It's satisfying as fuck walking up to a printer that's still signed in, scrawling a comedy dick in red pen on a bit of A4 paper, and using the cloud scan function to scan it and have it directly emailed to the user as a PDF.
I'm pretty sure there's some serious security issues there but it's funnier to hear someone's "new email" tone, and their eyes widen when they've got an email attachment from themselves making a suggestion that they crudely be elsewhere, or who see a masterpiece drawing of a hairy rocket with a helium leak manifesting itself from the very top.
