Answer 1

If some service is "listening" on a port, and this port is not prohibited on the Windows firewall, then it is open.

Answer 2

I also need it to access the printer via the Internet, but it does not work. It seems that I opened port 445 on both the router and the firewall. The printer is shared locally.
