Hi there and welcome
remove the USB plug on the computer and tell me what color it is inside the plug please
Can you please remove the power to the printer (so unplug it from the power socket).
Then wait 10 minutes, connect the power again to the printer, turn it on and tell me please if it is now operating correctly.
Let me know the results please
Can you please connect it to a different USB plug on the computer and tell me if it then prints from that?
