Read RFID

We use Zebra's R110XI4 for our printing needs.

I want to develop a small python script that can read the RFID value of the sticker being printed. I found this Bidirectional communications using Python | Zebra example, but this is more geared towards someone that wants to develop a program that sends information to the printer. I just want a way to read the EPC value of the RFID tag (for custom validation) being printed using Python. Can I use sockets to read this information?

Any help will be appreciated. Thanks.
