Generate various barcode formats like Code 128, EAN-13, and UPC.
The entered data may not be compatible with the barcode format, or the barcode image quality may be low. Check the data format and try again with higher image quality.
EAN-13 or UPC are commonly used for product sales, while Code 128 is often used for internal management. Choose the format that suits your purpose.
Print the barcode image at high resolution to avoid pixelation, and ensure a clear contrast between the background and barcode colors for good scanning.
