Print Labels with Zebra Printers with C#

[arturm]

We have recently acquired a Zebra ZD421 and are trying to figure out how to print labels with it from our C# program. Currently we are also using a different printer, a Brother QL-800 where we simply:

1. We design the Label template in their label design studio software (P-Touch Editor)
2. We save the label template as a .lbx file
3. In C# code we supply the .lbx file path and object data/values to the BPAC C# SDK/API
4. Printer prints the label

This workflow is working fantastic in Brother and is really nice. Can somebody give advice on how to do the same/similar with the Zebra ZD421 and/or in the Zebra ecosystem equivalent?
