Printer keeps going "offline" Windows 11

Indeed, they should use their own technology to investigate...

Same problem, every time I disconnect from the dock I have to reboot the laptop with the printer ON in order to reconnect to it. This is a Windows 11 issue as I never had this problem until forcibly upgraded to 11.

I don't have Norton, and it stills happens. Glad you could fix yours. I have Bitdefender and it was fine until one of those updates.

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.

Very late to the party here, but my Windows 11 machine does the same thing after every reboot, but it loses all printers, USB and Wi-Fi and virtual printer drivers like Microsoft PDF Print and CutePDF.  I can’t even use the Microsoft office Save As PDF option.

I agree that it happened after some update earlier this year but I found the simplest solution to bring all the printers back and it only takes about 60 seconds.  Go to the control panel and select Printers & Scanners.  You will see all of the printers off-line there, simply hit Add Device, let it discover everything, and within 60 seconds ALL of your printers will be back online and usable without any reinstalling or messing with any Wi-Fi network settings.  Annoying, but simple enough that I can live with this until Microsoft acknowledges the issue and solves the underlying problem.

Hopefully this simple solution works for others!
