Hello Micheal,
You can try adding the printer manually by filling in the IP address of the computer connected to the printers, this would be your Windows 11 desktop. If you don't know how, you can find it by opening the network adapter in the Settings app and going to the network properties.
Afterward, go to your laptops and add the IP address that is on your Windows 11 desktop. This IP address will change every couple days because of DHCP leases renewing, so make sure you either assign a static IP to your Win11 PC. A quick google search will show you results plenty.
Lastly, these label printers are connected via USB. Does the device support network printing?
Let me know if you encounter any issues
