How do I troubleshoot a 'Communication Error' with my printer?

A 'Communication Error' suggests a problem with the connection between your computer and the printer. First, ensure the printer is powered on and properly connected (via USB cable or Wi-Fi). Try a different USB cable if using a USB connection. Restart both your computer and the printer. If using Wi-Fi, check your Wi-Fi connection and make sure the printer is properly connected to your network. Also, check for driver updates.
