I hope this helps you. Whenever we install an operating system upgrade or some OS updates, printers and scanners will often stop working as yours did. Then a new OS compliant printer software must be installed and the printer may have to be reset. What you can do is to thoroughly check the printer web site for an updated driver that works. If one is not available, then you should ask when one will be released. If that doesn't work, if the printer has the Air Print feature, that can be used and no driver will be needed. If not, then you can check the respected web site below where volunteers write free drivers for older printers which are no longer supported, but which work with newer operating systems. It is worth checking out. Good luck.

What were you doing when you received this message?
Try booting to Safe Mode. That boot up takes minutes and clears caches and other things that may resolve your problem.

A lot of times just boot to Safe Mode followed by normal boot resolves problems.
