I have the Epson XP330 it was working great and then on Sunday my computer popped up an Epson update and I did the update not thinking anything of it and immediately my printer gave me an error message saying ink cartridges not recognized.  I had just printed a picture with it......  Long story short my printer is now a boat anchor any way to put it back the way it was??

In same cases yes you can. Roll back firmvare version you had before (downgrade).
