Printer keeps going "offline" Windows 11

UPDATE: My problem is solved, although I don't know why it happened suddenly since I'd made no changes in my system settings.
Solution: Settings --> Network & internet --> WiFi --><Name of my WiFi network> --> Private network

It had been set to Public network (Recommended) which MS says to do for a home network. When I changed it to Private network the printer no longer disconnects when I power down the computer. Now...I don't remember how or when it was set to a Public network, but this is how I found it. The setting worked OK until a recent Win 11 update. Now my network is a Private network and I'll keep an eye on it after upcoming updates. Hope this helps someone.

I am just stated having the same issue with multiple printers all of a sudden. When you run the troubleshooter in windows it starts to work. They both ping fine. Im suspecting a windows update

I have the same issue with an Epson ET-5180. I have it connected to my computer via a USB cable, and it still keeps going offline. I had that problem when I had it connected wirelessly. When I switched to USB mode, it worked great until last week (today is Thursday, 05/09/2024). Now it goes through the same frustrating problem. You get the same useless generic pat answers from Epson. I uninstalled the software and reinstalled it. It printed fine. When the printer goes to sleep (I guess that's what it's called), and I attempt to print something again, the printer is offline again and unable to print anything. Very Very frustrating!

I had the same problem.

I did everything and all steps Microsoft suggested, but nothing worked until I cleared my printer spooler and restarted it.

I followed this instructions:

Clear Print Spooler on Windows 11 (windowsloop.com)

Works great now, doesn't go off line since doing this

I'm having the same issue and it's wasting my time
