Because you are probably scanning the wrong ports. I told you, months ago, how to do it. To find a networked hp printer, you probably want to do: nmap -p 9100 -n 192.168.1.* <https://lists.opensuse.org/archives/list/users@lists.opensuse.org/message/H2ITIG6PSYYKHAMSUWVDVYQVVMU5IXDI/> However, the IP will be the same as in the other system. -- Cheers / Saludos, Carlos E.

Fire up Wireshark to see what's happening. Strictly speaking, it is possible to network without an IP address. At the lowest level, only a MAC address is needed. Way back in the Dark Ages, before IP became popular, Windows (and DOS & OS/2) used NetBIOS, which worked with MAC addresses. With IPv4, ARP is used to resolve IP addresses to MAC addresses. https://en.wikipedia.org/wiki/NetBIOS https://en.wikipedia.org/wiki/NetBIOS_Frames

Are you asking what the IP address is or are you asking why W/10 and Mint have smarts that nmap/openSuse don't have? How are these all connected? Is this via a switch (possibly as part of your router) as the backbone device? Is it handing out addresses via DHCP? There is going to be some way to address the management function of the switch to get it to report what it thinks it has connected and why. Or, perhaps, there's a matter of a different subnet... -- “Reality is so complex, we must move away from dogma, whether it’s conspiracy theories or free-market,” -- James Glattfelder. http://jth.ch/jbg

I'm asking what the ip address is, and why I can't find out. However, I certainly do note that Windows and Mint and perhaps other systems have and why such basic needs cannot be met by a sophisticated system like OpenSUSE Leap. (The nmap claims to be the same on both systems.) I might not have found the Windows facility without having to go to that confusing system in order to print things! How are these all connected?

There is going to be some way to address the management function of the switch to get it to report what it thinks it has connected and why. Right now, I have not set any static ips, altho the HP printer might have one: 192.168.0.103.
Or, perhaps, there's a matter of a different subnet... Everything is connected by cable on the lan thru a "D-LINK DIR-632 wireless N 8-port routerwith an unused wireless function. Description is off the 'net.
I'm not at all familiar with the details of the lan operation--I don't know what subnets might exist or why, or how to find them if they do. With regard to wireless operations: I have been wiring these kind of connections since about 1985 or so and I trust them more than wireless, especially since I have an S9 noise level on the low ham bands. Yes, I've been at this for a while now, since CPM, and now I'm an old man and maybe not as sharp as I should be. . . . --doug

Run Wireshark, filtering on the printer MAC address. You could also check the arp cache, after printing something.
