Research direction
Start by comparing USB.findPrinter() behavior on the local machine and the Ubuntu 20.04 VPS, then inspect the output of lsusb on the server. Check whether the VPS can see the USB printer at all and whether the reported build prerequisites are sufficient; done means explaining or reproducing why the printer is unavailable in the deployed environment.
