My HP Deskjet 2130 series is showing an 'Error Printing' message and the error code is '0x4'. What does this code signify and how can I fix it?

Error code '0x4' typically indicates a communication error between the printer and the computer. Try resetting the printer by unplugging it from the power outlet for 60 seconds and then plugging it back in. Ensure the printer drivers are up to date and that the USB cable (if used) is functioning correctly. If using Wi-Fi, verify network connectivity.
