Turn the printer Off. (Disconnected from the computer of course.)
Then after 1 minute or more, turn the printer On...
...and within about 4 seconds (1... 2... 3... 4...) pull the power plug, sharply and suddenly.
Leave it that way for 10 or more minutes.
Plug the printer back in to just the power.
Wait for it to initialize, which will take 5 minutes or so, roughly.
Then connect to the computer, and try to print to it, regardless of whether it still has an error on it. (I hope this doesn't simply Blue Screen your computer again.)
I myself just did some random efforts by turning the printer ON and OFF, plugged the electric cord IN and OUT, or connected and disconnected the USB cable connecting the PC and the printer.
Thanks
