I have a problem with blank labels using ZPL from iOS application to print the label.
We use printer QLn 320 Zebra with firmware V68.19.7Z, non-continuous media with gaps.
The printer prints one required label and two blank labels when I use the ZPL command:
If I change printer settings and define label length with command:
and use the following ZPL to print the label
The printer prints labels with correct size and doesn’t print blank labels.
So as I understand the problem with auto detection label size.
Could you advice what can be the reason?
