I have 3 Clover station (1.0) printers that stopped working one by one. When I open the "Printers" it does not show a receipt printer connected. We replace the cables, and even swapped out the print hubs. One of the stations is printing again, but we can't get any of the others to work. We even swapped the working print hub with the other 2 non working units, but no resolution. Any advice?
