A lot of modern printers are hooked up to your router either via cable or WiFi rather than directly to your computer.
UPnP stands for Universal Plug and Play. It allows devices on a network to find each other easier. In some cases, UPnP can also do port forwarding to let external devices or services access your network easier. It’s not that uncommon in say video games where different video game clients need to talk to one another.
I’m honestly not sure why a printer would do that. Incompetent or malicious printer manufacturers perhaps. There is plenty of proof for the latter.

I’m not really a networking goddess but I think having ports open to VPN traffic is a good idea.
