19GS1 Digital Link & Sunrise 2027 migration

For the move to 2D barcodes at the point of sale ("Sunrise 2027"): Gs1DigitalLink builds, validates and parses GS1 Digital Link URIs after URI Syntax 1.7.0 (element string ⇄ URI, custom domain, canonical URI). ZplGs1Migration adds a QR Code with a Digital Link URI or a GS1 DataMatrix to existing ZPL labels – in free space next to the EAN/UPC, with quiet zone and clearance measured on the rendered label – and checks the result with the sunrise pack.

Before: EAN-13 only

After: EAN-13 + QR with GS1 Digital Link

An assistant and pre-check, not a certification: verify printed labels with a barcode verifier and agree on them with your GS1 Member Organisation or retailer. ^BQ cannot encode FNC1, so a GS1 QR Code with element strings is not possible in ZPL – the QR Code carries the Digital Link URI. Legacy compressed Digital Link URIs are read only. GS1, GS1 DataMatrix and GS1 Digital Link are trademarks of GS1 AISBL.
