It's not that. Apparently, several major Linux distros, and the cups-browsed developers, have decided for people that any device on the internet should be able to connect to their system as a printer.
- BenjiWiebe 2y agoHow do they get around the built-in firewall that's been standard on home routers for the past 15 years?

I don't know what default firewall rules are configured, but on distros that run it I'd assume it's allowed through, otherwise no reason to run it.
