Worked example
A dispatcher places DOC-107 and DOC-108 on a Letter sheet, selects Save as PDF, then checks that a scanner reads both codes from a printed proof.
Before you print
For standalone artwork instead, choose Download SVG. Print at actual size so barcode width and quiet zones are not unexpectedly scaled.
Barcode artwork is not proof of an assigned GS1 number. A free barcode image and a GS1-issued GTIN are different things.
