Hello, I’m Virginia a fellow Windows user.
I take it the printer is connected via Bluetooth or WiFi rather than cable? If not then please let me know the connection method other than cable as you say that method does work.
Have you re-run the WiFi set up program to ensure it is still connected?
Is the WiFi light (if it has one) still lit?
Have you visited the Epsom website to see if there’s any newer drivers, firmware &/or software updates?
