I have completed several government retail scale interface certifications. Any weighing scale that is certified for commercial use has to show the data cannot easily be tampered with. For this reason it would not be possible to certify a scale with a network or wireless connection. Hence they are all serial interfaces, usually RS-232 or RS-485. In theory a USB interface would achieve the same level of trust, but given the added complication during certification of driver support for a wide variety of connected hardware, i doubt any manufacturer would bother. If you really need network capability, your best bet is a RS232-to-virtualCOM-over-ethernet adapter.
