A barcode font is a quick and easy way to create a barcode and a lot cheaper than buying software to create the barcode, so what could be wrong in using a Code128 font?<\/p>\n

A Code 128 barcode breaks down as follows:<\/p>\n

Start character
\nData characters
\nChecksum character
\nStop character<\/p>\n

The start and stop characters are usually created by entering a character such as \u00cb and the stop character might be \u00ce but the checksum character needs to be calculated from the values of the other characters<\/strong>, and this can’t be done by a font (jump to the code 128 specification <\/a>for details on how this can be done).<\/p>\n

So the short answer is – don’t use a Code 128 font for creating barcodes, use something simpler like a Code 39 font<\/a> which doesn’t need a checksum character.<\/p>\n

If you do want to use a Code 128 font and can’t generate a checksum then you can disable the necessity for a checksum in our software with the following setting, but you will still need to make sure you get a start and stop character in your barcode:<\/p>\n

Code128DebugMode = 1<\/p>\n

HINT: The stop character consists of 4 bars where as all other characters have 3 bars.<\/p>\n","protected":false},"excerpt":{"rendered":"
