Barcode label language

Hi guys!

I just integrated RMS to our store operations, and learning the program as I am using it. I came to encounter one problem: I cannot print barcode!!!

I use TLP2824 (Zebra printer), and questions are followings:

1. Zebra support says POS send ZPL language, and my printer uses EPL language. How can I change the POS to send EPL instead of ZPL?

1. Default label selections (when I use label wizard to print barcode) it doesn't show up the size I am using (I use 1.25 X 2.25)

2. I made barcode format file (to suit my 1.25 X 2.25 barcode label size), but the selection doesn't show up.

Your help is highly appreciated!!! Thanks~
