While I'd try it wired and install Dell's latest drivers, more is needed for clues. That is, I'm running into this when folk install a VPN. Nothing's broke about that, that's what a VPN should do.
My Dell B1163w wireless printer (Win 10) says it's "offline" and won't print. In Devices and Printers/What's printing, I unchecked "Print Offline," but that didn't seem to help. I also unplugged the router and re-plugged, but that didn't help either. When I attempt to print the printer makes the typical noises that one would expect when it's going to print a page, and then nothing happens.
Sometimes I get a error message and other times it just says the printing was completed -- but doesn't print. Ran Troubleshooting and I get an unexpected error and so it's of no use to me.
Thanks in advacne for your help
