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...

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.exe
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.
I think at various times I've had AngryIP blocked by various av
software etc despite it having been around a while
Others may have guidance on port scanning but there is another thread
on printing to windows 10 and it notes that AngryIP can scan for open
ports (Options-Select Ports ie range).

Thank you very much for your purposefully helpful advice on ipscan.
I don't use AV programs so I'm fine with AngryIP ipscan, which I like.
o AngryIP ipscan is simple - it just scans for devices & open ports
What it found for my printer turned out to be correct
o I hadn't realized my printer had port 80 open, but it did!

In another thread, I'm trying to get printing to work from Android
directly from my Android phone (on my LAN via Wi-Fi) to the Ethernet'd >printer (on my LAN on the same subnet).
o Do you use Windows to print from your Android to your printer?

One thing that comes up is "CUPS", which seems to use port 631 by default.
o <https://i.postimg.cc/6qRSK6WY/printing11.jpg> Turn CUPS print server on
o <https://i.postimg.cc/9fMnMYX4/printing12.jpg> CUPS wants to use port 631
That begs the question of "what port" do printers normally use anyway?

I've never printed from my Android but I've just switched my Epson
X)-6005 on which is connected to my WiFi (and a direct USB to my
notebook).
I then followed the Android's Help which says to go Connected Devices, >clicked on Connections preferences and then Printing which after a few >seconds found my Epson via Default Print services.
I don't know if there is a normal and I don't know which my setup
would use. I thought 80 was an output port only.

Hi AnthonyL,
Thanks for that purposefully helpful advice, where you'll find a lot more >information about this problem set over here, in comp.mobile.android:
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>
While I am ecstatic that printing works so easily for you with your Epson >XP-6005 printer, you have a completely different setup, I think, and that >matters a lot (unfortunately for me).
o EXPRESSION PREMIUM XP-6005 Wi-Fi all-in-one ><https://www.epson.de/en/products/printers/inkjet-printers/for-home/expression-premium-xp-6005>
My printer is an HP LaserJet 2100tn (which has an Ethernet card):
a. Mine is not wi-fi enabled
b. Mine is not hooked up to a PC via USB (or anything other than a router)
c. Mine is hooked directly to the router via Ethernet
While even with my setup it's easy to print if I use the "cloud" as the >printer driver, the goal is to print using our own LAN.
I am exploring _some_ solutions (many of which are from F-Droid), as the >whole goal is to come up with a solution that not only benefits me, but,
that benefits everyone else at the same time (who has the same problem).
One issue I have in debugging is understanding the role of:
a. Where is the "printer driver" when printing from Android?
b. Who is the "printer server" when printing from Android?
Those two questions are ones I never thought about until I needed to debug >why it's so simple to print from Windows over the LAN, but not Android.

Hi AnthonyL,
Just did a nice helpful reply - actually I think there are one or two
clues that may have helped - then saw the other thread in which you've
solved it.
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 think, perchance, the ipscan lied to me.
o Or maybe it's just the wrong tool to find the printer's ports
Note that it turns out HP printers use, by default, port 9100.
o So the question is why didn't port 9100 show up in the scan?
This is a quick test of port 9100 on my printer over the LAN:
o telnet 192.168.0.20 9100 (connects, but I can't talk printer protocol)
o telnet 192.168.0.20 9200 (fails, I chose that port arbitrarily to test)
So my HP LJ 2100tn is listening on port 9100.
o But then, why didn't the ipscan show that to be the fact?
I doublechecked the automatically set settings in Android LetsPrintDroid:
o <https://i.postimg.cc/L5Pfd7xc/printing14.jpg>
Notice they _also_ confirm LPD automatically chose port 9100.
o <https://i.postimg.cc/bYS12Dqm/printing15.jpg>
Does anyone know why the ipscan didn't catch that HP's use port 9100?

As mentioned previously try the Android app Port Scan from the Fdroid repositiory.
How do I find the IP address of a printer on my network? Thanks.
