Windows does this too, I believe. At least it did it with a Xerox laser printer I bought and the Brother printer at my friend's place.

Windows does have a significant mitigation: whenever you connect to a new network, such as a coffee shop Wi-Fi, it defaults to considering this network Public (untrusted) and firewalls any such services from accessing it/being accessed from it. You have to explicitly set it as a "Private" network for file sharing and printer discovery and similar to work.
