Good day, each time when you connect usb printer to the PC virtual printing USB port name (USB001,USB002,etc) is assigned, once you install the driver this assignment is remembered and as result the more installed printers you have in the system the higher is port number for the next one. Unfortunately, license.exe can only work with first 32 ports, so in order to use it with the new device, you need to delete one of the existed printers with low port number, freeing it, and then replug the new one (of course it will only work if new device is not installed itself, otherwise it will have fixed port number and nothing will change). Bottom line, remove as much unused printers from the system as possible.
