Sample input
Use two complete ^XA…^XZ labels, with distinct LABEL A and LABEL B text.
Expected result
PNG exports the selected zero-based index. PDF exports all labels in their source order at the selected page size.
Failure and correction
Index 1 is the second label. A single-label input with index 1 fails; choose 0. Old images are invalidated when source/settings change.
Support and data handling
Preview/PDF uses Labelary. PDF is a proof, not a replacement for the original production ZPL; verify output with your printer workflow.
