Saving connection details to use for auto connection

Hi,

Im working on the Link OS SDK (previous generation) and can successfully connect via USB > select printer > print demo ZPL using the demo application.
the printer.Address = "/dev/bus/usb/001/002".

the model im using is the ZD420 with USB interface only.

Given the address, how can I create a Connection object using connection builder?

So that i can simply print the data after the first printer selection.
