If it is the same driver setup on the same server printing to the same machines and only one has an issue, the next steps are to perform a software/network reset at the device, then run an Image overwrite at the device. If it still fails the final step is an ALTBOOT, which will entirely wipe the device, if it comes to this step, make sure you do not clone itself, clone from one of the other devices instead (If you do so while the network cable is unplugged, the only thing you will need to do once complete is to re-enter the proper IP address as everything else will be done.
