Top mistakes sellers make
The biggest issue is printing the full A4 page instead of the actual label. This makes the barcode smaller, adds unnecessary invoice content, and creates poor workflow when you are handling many orders daily.
Another common issue is using the wrong page size for thermal printers. Amazon documents are usually designed for office printing, not 4x6 shipping label rolls, so the format must be standardized before printing.
How to avoid them
- Check that the PDF is still in marketplace label format and not a generic invoice PDF.
- Remove the tax invoice section or extra document text before printing.
- Use a consistent 4x6 thermal format for the final output.
- Print from a merged PDF to save time during dispatch.
Best fix for Amazon sellers
Use a browser-based label cropper that automatically detects invoice boundaries and keeps only the shipping label portion. This saves time and prevents barcode scanning problems during courier pickup.
