Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I advise you to

2. obtain a new driver from this site:
3. uninstall the printer from your computer.
4. restart your computer

This may get it working again. Let me know how it goes, and whether you run into any problems on the way.
