Default Printer's IP address

How do I find the IP address of a printer on my network? Thanks.

I don't know. How do _you_?

I use nmap sometimes. I walk up to the printer and select the print
system information option sometimes. I walk up to the printer and find
it on the on-screen config menu sometimes.

With DNS service discovery, I can sometimes find the printer by name,
and not need the IP address:

$ lpinfo --include-schemes dnssd -v
network dnssd://Brother%20HL-L6200DW%20series._ipp._tcp.local/?uuid=e3212300-80ce-11db-8000-3c2af4123123
$

That is on Linux, YMMV with other operating systems. Your lack of detail
about the printer, the network, and the OS(s) involved doesn't help.

Windows should have an nmap equivalent, maybe even called nmap

If you log on to your router, there will be a page with a list of devices
and the I.P. addresses asigned to them. There will be something that
identifies your printer, perhaps something like Epson... and beside it you
should find your printer's MAC address and I.P. address.

I'm a long time user of

https://angryip.org/

especially when it comes to sorting out my network but finds all
devices that have an IP on the same network.

Run a decent DHCP/DNS server on your LAN and the printer will have a
name. I use dnsmasq running on a Raspberry Pi and so all the systems
and devices on my LAN have names. No need to know IPs.

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

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?
https://groups.google.com/g/alt.comp.microsoft.windows/c/6ScU1H5Q43U

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.

Another app I find useful is Port Authority which is available from
Fdroid. Quick scan of all your network and a port check too. If
you're not using the Fdroid repositiory you should have a look. I go
there nearly always in preference to Play Store and have a number of
useful apps, some of them the same as Play Store but without ads!!

I've just printed something out, quite easily once I selected
colour/mono as an option. I wonder if Port 80 is to deliver printer
information and one of the other Ports to send the printing to?
