Question

I want to scan printer IPs in my organization. Is there authentic method? I am using Nmap. I have already checked some commands like:

1) nmap -O 10.10x.x.0/24 -oG - | grep printer >> outfile
2) nmap -p 9100,515,631 192.168.1.1/24 -oX printers.xm

With option 2 I have obtained an xml file, but I don't how to read this file to identify printers because I got many IP's whether they are PCs or printers.

Nmap scan report for 192.168.x.x
Host is up (0.00082s latency).
PORT STATE SERVICE
515/tcp filtered printer
631/tcp filtered ipp
9100/tcp filtered jetdirect

Kindly help me to find out printer IP. I am really messing up. If you want to suggest any command kindly also add some brief instruction for printer IP identification. One more thing, what is filtered state here?

Explanation / Answer

nmap really isn't designed to do what you're looking for. You would have to know exactly what you are looking for and grep the output for those things, just like you did in your example. But that will only work if the printer responds to pings, and if printers return the results that you expect.

You might be able to eliminate some results by knowing what the OS is on the printers and eliminating results that do not report that OS.
