I have spent literally hours trying to fix this, yet another, incredibly frustrating and ridiculous bug in Windows 10. From just my Google searches, this is an unacceptably common problem. My home wireless printer is turned on, has an IP address, etc. Yet Windows 10 states it is offline and it is impossible to get anything to print. I have tried everything, deleted the printer, re-installed, reset network on printer, etc. etc. etc. When I try to configure the port address as several internet searches have suggested, I get "an error occurred during port configuration. the operation is not supported". Please help fix this!
