I have a similar question, of greater detail, in that I know what my
printer IP address is, but I don't know how to find the _port_.

The reason the port matters is simply that some Android programs ask:
o How do you print from Android to your home networked printer on your LAN?
https://groups.google.com/g/comp.mobile.android/c/nTAYljkvVl4

Hence, I'll try this "angry IP" app to see what it tells me about my
o HP LaserJet 2100tn (connected on the same LAN subnet via Ethernet)

... My ad hoc sysinstall log follows...
mkdir x:\installers\network\scanner\angryip

Run this IP Scanner 3.73 installer executable
It wants to go in C:\Program Files\Angry IP Scanner
I put it where it belongs C:\app\network\scanner\angryip
Note: You decide that; not a thousand different companies.
It installs quickly, with no obvious shenanigans (good).
Create a shortcut C:\menu\network\scanner\ipscan.lnk
Target C:\app\network\scanner\angryip\ipscan.exe
Start it: Taskbar menu network scanner ipscan
Uncheck [x]Send anonymous error reports
Hit [Next] quite a few times, and then [Close]

I'm not sure what to do next but I hit the big green "Start" button.
Aha! Up pops a Windows Defender Firewall blockage report:
Java(TM) Platform SE binary
C:\program files (x86)\common files\oracle\java\javapath_target_18549781\javaw.e xe

Scanning completed (it took about 20 seconds).
o IP Range 192.168.0.1 - 192.168.0.255
o Hosts alive: 9
o With open ports: 6

OK. I scroll down to find the printer, which doesn't show up "as" a
printer, but I happen to already know its IP address, where it says:
o IP = 192.168.0.20
o Ping = 2ms
o Hostname = [n/a]
o Ports[3+] = 80

I'm not sure what the "3+" means, but the rest seems pretty clear.
o Thanks for this advice to use this freeware Windows network scanner.
