I am not familiar with the value of the third number in the ips. I seem to remember that 5 or 6 years ago, all my ips had a 1 in the third position; now they all seem to want a 0.
Well, your router changed, didn't it? Then the numbers can change, 0 and 1 are typical, but it could be 132, or 83, or 200, for instance.
Anyway, not discovering the Epson printer ip, if any.

ok, try:
nmap -p 3289,515,9100,631 -n 192.168.0.*
I found in the printer manual, a way to get a status sheet from the printer's control panel. It shows that the original static ip address that was set back around 2016 is still in effect. I suspect that whatever is supposed to decode that from a ping has been blown out, since it does not respond to a ping at that ip. Now I mentioned earlier that the third number in the ip addresses on my network now is 0, where it used to be 1, and one of the correspondents here suggested that this is router dependent. Will the router not interrogate an address with a 1 in the third position? (The old router was destroyed in the lightning strike--I can't put it back and try it!) It seems that there are unknown failures in the printer, in addition to the one already found--the FAX line is zapped. comments? --doug

We're going round in circles. The printer was set up to be 192.168.1.26 back around 2016 or so, and it worked that way--even in OpenSUSE Tumbleweed-- but I could never get it (or the HP, either) to work in Leap, either before or after the lightning strike.

I discovered the hard way that it is EXTREMELY difficult to enter anything into the printer via its control panel. Is there any reason you know of that I should not be able to ping 192.158.1.26 on the lan? Such a ping does not respond: linux1:~ # ping 192.168.1.26 PING 192.168.1.26 (192.168.1.26) 56(84) bytes of data. ^C --- 192.168.1.26 ping statistics --- 14 packets transmitted, 0 received, 100% packet loss, time 13295ms --doug

It is IMPOSSIBLE to access a printer on 192.168.1.26 when the network is 192.168.0.* No matter how difficult it is, you have to tell that printer, using its panel, to use a different address in the 192.168.0.* range. The alternative is to configure the new router to change to 192.168.1.1, and then configure anything else on that network to change back to 192.168.1.* Your choice of difficulty. I would change the printer. You can give the printer a fixed IP on the printer panel, or also in the panel set it up to use an automatic address. Once done this, you have to enter the router configuration to ASSIGN a fixated address to the printer.

Perfect! Just make sure to select an address that is free and not in the router pool for automatic addresses. Notice that the printer may have a web page of its own to change its own configuration, but reaching it is not easy as you are in different lan sections (the third number is different). It can be done if you connect printer to computer directly, single cable, and change the network configuration of the computer temporarily.

That's not easy to tell, because each router does it a bit different. I would have to read that router manual. If the router is provided by your ISP, then it would depend on how your ISP sets up your router. Ideally, there would be a manual from your ISP, so have a look at your ISP web help pages.

Ok, if you notice that your automatic IPs are getting numbers like 100, 101, 102... chances are that you can manually assign numbers starting from 2 up to 99 - but this is a guess. So, yes, you could use number between .10 and .29. That is, SMALLER than .100. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))

You're free to designate the beginning and ending addresses of the pool if your router is like most cheap routers.

On a router provided by the ISP and with a configuration provided by them, I prefer minimal changes (minimal interference). In the case of my ISP, the routers are configured (and maintained) remotely by the ISP, not the clients, who do not have the password (but the client can request the password and take over). In the normal case, the client logs into a remote web page at the ISP, where he can do just a few changes, and then the ISP applies them to the client router, independently of brand. It is not that simple to make generalizations. So unless you know why they do what and how they do it, the generic rule is "minimal change". In this case, look, and don't change, adapt. That way, if you have to phone the ISP for help, they can help. If you change things, it is up to you, no help. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.2 x86_64 (Minas Tirith))

Given Doug's in my time zone, it's safe to assume that he, like most north Americans, is far less likely on DSL than cable, where routers IME historically have been owned mostly by users. It's only relatively recently that cable providers have bundled their own routers with/in their modems to further gouge subscribers. I've never used a router supplied by a provider, and only briefly used a provider modem. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.

My ISP, Rogers in Canada, has always provided the modem, going back to the late '90s. However, some resellers allow customers to buy their own. Also, the main phone company also provides modems for their ADSL customers.

Originally, Rogers provided only a plain modem. Then "gateways" which included a router. Now the box I have does Internet, home phone and IPTV. However, since I have put it in bridge mode, the router & WiFi are not used.

It turns out that the last time I did was in 2012! I don't know why I replaced it somewhere along the way. Almost all the hardware it connects is newer, so I'll have to adjust it one of these days. Just one more thing to do.
Carlos suggests that I use ip addresses similar to the automatic ones it assigns, and that makes sense, even tho it's one more character to type anytime I need to access something by its address. I am grateful for all the assistance that I've found on this path here! --doug

If the router is yours, you could change the IP range to be 192.168.1.* and problem solved.

Er... no, different addresses. The router is, apparently, assigning addresses starting with .100 onwards, so you can assign (probably) address lower than 100.

This is another can of worms. AFAIK, Linux needs the printer to be always in the same IP address, so then you must reconfigure the router to assign always the same IP to the printer.

Thanx again to all who participated in this long-running tale of woe! --doug Doug, here's a tip to file away: In the IP address configuration of any network-connected device, there are 3 key parameters:
IP Address Netmask Default Gateway. The IP address is what you've been looking at with your printer -for IP version 4 it is expressed as a "dotted quad" of 4x 8bit decimal numbers for a total of 32 bits, each octet ranging from 0 to 255 e.g. 192.168.0.100 as you've seen on your LAN. The Netmask tells each network device 2 key pieces of information: what portion of that IP address represents the NETWORK, and what portion represents the HOST (a "network-connected device"). The netmask looks like "255.255.255.0", or "255.255.0.0", or other combinations (I won't get into more complex netmasks here"). In the case of 255.255.255.0 (in binary notation that would be 11111111.11111111.11111111.00000000), the first 3 octets (everywhere that the bits are all 1's) represent the NETWORK portion of the address, and the last octet (or everywhere there are zeros) represents the HOST portion of the network address. Computers on a LAN can talk directly to other computers where the NETWORK portion of the address matches - if the netmask is 255.255.255.0, that means the first 3 octets of the address must match; if it is 255.255.0.0, only the first 2 need to match. In case 1, there are a maximum of 254 host addresses possible (.1 to .254, .0 is the "network address" and .255 is the broadcast address i.e. ALL HOSTS get packets addressed to .255), and in case 2 there are 255*254 hosts available (host addresses are x.x.0.1 to x.x.255.254). The default gateway address is the router address - if the devices are trying to talk to an IP address that does NOT have matching octets in the positions specified by the netmask, they will forward that traffic to the default gateway address, in the hope that the router will know how to deliver it (if not directly, it will forward it to the next upstream router that it knows about, as long as it has a default-gateway configured for itself - that will be an address on your ISP's router. IP addressing is analogous to sending a letter through the mail - as long as the letter is correctly addressed, you only have to get it to your local mailbox (the "ethernet port", which gets it to the local post-office (the "router"), which sends it onto the mail processing facility (the upstream router in "the cloud"...penultimately it gets delivered to a local post office at the far end, and then to the final destination. That's basically how networking functions, only with bits and bytes on "the wire". It gets a whole lot more complicated than that, but if you can follow that for now you'll be a lot further ahead than you were when this saga started.
