Zebra ZXP Series 3 - Magnetic encoding

Trying to magnetic encode using the Zebra ZXP Series 3 connected to a mac.
I tried Google but couldn't find information on this.
2 questions:
- I can't find the option to print on 1 side and encode. Is this supported only on Windows?
- Goal would be to encode from a Word doc. How should the data be labelled? I can't find "Enable macro processing" on the settings window. Not sure how to label the data

Thanks for your help!
