Recently I lost connection to my HP Photosmart 7520 printer. Little investigation showed that printer’s IP address was changed. Printer was connected via WiFi. The current IP address can be looked up on WiFi settings page:
In Windows 10 printer can be found under Settings -> Devices -> Printers & Scanners
Clicking on device will bring up Manage option
Manage will open another options list
Open print app will bring up HP screen
As visible the IP address is old 192.168.0.51 and status in unknown.
Now click on Printer icon on left menu
and click Select a Different Printer. If printer is online then it should be visible:
Click on the printer and you are ready to go
