2) Also suggested: avahi-browse -rt _ipp._tcp This year, the output of that command no longer contains my printer's IP address. Last year, it did. I have no idea why this has changed.
Avahi was mentioned in the ipv6 thread, so I decided to read links on the Debian wiki page
https://en.wikipedia.org/wiki/Avahi_%28software%29
Avahi's performance resembles that of Bonjour, sometimes exceeding it; however Avahi can lose services when managing large numbers of requests simultaneously.[3] 3.

Unsure if it is relevant
4) Also mentioned: port 9100. For grins, I did "telnet 10.76.172.100 9100" and after that connected I typed "HELLO WORLD", then pressed Enter, then Ctrl-] q Enter to close the telnet session.
I am curious if there is some tool convenient to get report concerning various service service discovery protocols provided at some ip (mDNS-SD, uPnP, etc.).

Does anyone know what technology is used by windows nowadays (Simple Service Discovery Protocol, SSDP?) and which tools can be used in Linux to get list of services?
