How to read and store UHF tag UID using python and zebra

Question

I have a zebra R110Xi4 printer and i am struggling to pull the tag UID and encode it to the EPC,using just ZPL to do it is not possible so i was thinking to use python to do it in 2 steps (read and encode) so far i found several ways to use python to send ZPL and EPL command to it but not how to get information back from the printer .

I wanted to know how can i read and store the UID of the tag using the Zebra module(or any other way) and not just encode and print it.

In simpale words i want to read the UID of the tag, do some manipulation to it and write it back to the EPC.

Zebra python module: https://pypi.python.org/pypi/zebra/

There is another option to use TCP/IP to send ZPL to the printer but i know that i cant get information back from the printer using TCP/IP

I'd skip the Zebra Python module as it looks like it outputs EPL, and I'm not sure EPL provides the necessary commands to write RFID tags. You can get a response back over TCP/IP though. Take a look at this example in C# km.zebra.com/kb/index?page=content&id=SA140&actp=RSS — Elton Saunders

To get the TID and encode into the EPC, I've done this, which stores the encoding command then backfeeds to the correct tag and print/encode the TID onto the EPC. I used the Zebra RZ400 and the tag itself is EPC Class 1 Gen2 and has a 96-bit TID. It may differ depending on what tags you have.
