Barcode Scanning

I have printed a Code 128 barcode but my scanner won't read it.

Given that the print quality and resolution (200 dpi or higher) are ok, with Code 128 most scanners will expect a checksum with the barcode. If the code will not scan you may have printed it without a checksum.

Another option is that the scanner has been set to expect a minimum length of data, e.g. eight characters. If you encode less then eight characters, the code will not scan.

Right-click and "Save as..." the barcode below to download a high quality 300 dpi Code 128 sample with proper checksum. You can print it out and thus verify the settings of your scanner:
