Hello. I'm having problems with my  ENVY 5020 All-in-One.

For some time it had been showing as OFFLINE and didn't print from PC but worked from mobile using e print and also via email. 

The other day I reinstalled the printer through HP Smart and it worked once then went offline again. It still worked through e print and email.

At all times, it was connected to my WiFi network and showing IP address, solid blue light etc.

Today, while trying to resolve the issue I switched on and off, unplugged and plugged in, restarted PC, uninstalled and reinstalled all drivers (including deleting from print server settings, deleting folders in HP folder etc. No luck. I've run trouble shooters, Print and Scan Doctor, all to no avail.

Then I reset the printer to factory defaults and it now it won't even print via e print nor email. On restarting, it said the printer had to be enrolled in Instant Ink to be able to print.  I resolved this by going to Network Services and activating, upon which it assigned a new, completely different email address which apparently can't be changed(?)

Printer now shows connected to WiFi with the same IP as before, tapping on envelope icon it says Printer is Ready, status reports can be printed, but ABSOLUTELY NOTHING will get the printer to show up on PC, and no longer prints via email nor e print either. Internet, WiFi, everything else in in order.

The only thing that does work is installing with USB, but wireless printing will NOT work, only via USB.

I'm at my wits end. I really hope someone can help and thank you in advance!
