Frequently Asked Questions

Which format should I use?

Code 128 is versatile and supports the full ASCII set. Use EAN-13 or UPC-A for retail products, and Code 39 for simple alphanumeric labels.

Why does my barcode not scan?

Check that the data matches the format requirements (e.g., EAN-13 needs exactly 12 or 13 digits) and that the print resolution is sufficient.
