Reroute Micros workstation 4 control hot remote

We have 3 workstation4(names: Restaurant, Bar and Cashier). Cashier is out of order and had to be serviced. This one controls the kitchen cold remote printer. I took the Bar workstation and plug it in Cashier’s spot. But all orders to kitchen will not print to cold remote. I went into DEVICES and changed Network Node from Cashier to Bar but still would not work.Warning: Comport on this device has changed. Please change your settings. What settings?
Thank you in advance for help.
