To find a networked hp printer, you probably want to do:
nmap -p 9100 -n 192.168.1.* ran that in Windows, but got no answers:

Then tried with the third entry set to 0 and got this:

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. Well, I told you the trick for HPs, not Epson. I don't know what port the Epson uses.
Google "what port uses an epson printer"

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
