Download does not mean ship-ready
Before using any downloaded PDF on a real package, test-scan the barcode, confirm the printed size, and check every address and customs field. If anything looks wrong, do not ship with that output.
What to check
A good test print should match the ruler
Measure the 100 mm reference line. If it is short or long, fix print scale before printing a carrier barcode. If the center crosshair is shifted, check paper size, margins and roll alignment.
