Store and Recall GS1 label with variables

Hi,

I made the layout for a GS1 label. The label contains different application identifiers (10-Batch or Lot Numbers, 15-Best BeforeDate) with non-static content.

Then I exported the label to my Zebra ZT420 203dpi. The idea is to use the SDK for parameter binding (which is working fine for EAN-13).

It seems the variable definition are not exported for GS1. The label contains the static information from Zebra Designer. It is possible that the printer is not supporting this feature ? Or is a limitation in ZPL ?

Can you help me please ?

Thank you

Dan
