Sometimes, the barcode you generate may encounter the following problems:

  • Difficult-to-scan barcodes or no response.
  • Not recognized after scanning.

If the error message is "not recognized" during scanning, please refer here for additional details.


Please use a scanner to examine the image below for each barcode. You will discover that the smaller one cannot be scanned, despite having the same barcode values.

  • Barcode images require additional space for proper display.
  • Make sure the barcode quality is crisp, and your printer has a minimum of 300 dpi or higher.

Please adjust the width of the barcode image to maximize available space. In most cases, longer barcode values require increased width for improved readability.
