Some barcodes such as Code39ASCII allow you to indicate whether to generate the optional check character. For example, the following command generates a Code39ASCII barcode with the check character.
The "1" at the end of the command indicates to generate a check character. Use a "0" to turn off the check character. In the above, "LibreOffice Writer" is used to display the barcodes. It is also possible to use the barcode fonts in other Linux applications such as Gimp, Inkscape or Mozilla Firefox.
