Last week this printer worked fine, this week it quit being recognized by one computer among 3 connected to it. I uninstalled and reinstalled the printer. Windows saw it and connected it, but then wouldn't print. Turning off Defender and Malwarebytes, got the printer functioning. Turning Defender back on, it still worked, but quit again when Malwarebytes was re-enabled. How do I fix this, and what happened to cause this in a previously functioning machine?
