The PC's power management might be shutting down USB communication. To resolve this, open the Device Manager and the list of USB devices, then disable shutdown for each hub in the list. You might need to restart the PC for the changes to take effect. If you are using a laptop, give it a few moments to enable USB communication after hibernation. Try unplugging and reconnecting the USB printer port. As an alternative, replace the PC port or the PC.
