If your HP Printer OJ 8710 isn't responding to print commands, several factors may be at play. Firstly, ensure the printer is powered on and connected to the computer or network. Outdated or corrupted drivers can also hinder communication. Update or reinstall the drivers as needed. Verify that the selected printer in your computer settings matches the OJ 8710. Additionally, inspect the connection cables or wireless network for any issues. If problems persist, consider restarting both the printer and the computer.
