Measurements for Human Readable fonts do not include the text below. * Measurements are approximate and were measured when printed at 12 points, which should work for most scanners. Purchased Font NameĬode 128 Fonts 'Character set B' (text below barcode:**)Ĭode 128 Fonts 'Character set C' (text below barcode:**) The N Dimension column in the chart below is the narrow bar width to height ratio. TrueType fonts with symbol encoding are also provided, which allow the font name to be more visible in font drop down lists of end-user Windows applications and are signified with the letter “Y” or the word 'Symbol' in the font name. Because each single font may be printed at various point sizes, there are several combinations of heights and widths that may be produced. The last characters in the Code 128 barcode font name determine the height of the barcode with the shortest being 'XXS' and the tallest being 'XXL'. Fonts with the letter ' H' in the font name are human-readable versions. Code AĮighteen different versions of the Code 128 barcode fonts are provided to support human readable versions and different width and height requirements. The character set provides easy methods of encoding functions in barcodes such as returns and tabs. The Char column lists the character that resides at the ASCII location, which can be used to print the corresponding symbol. These columns designate the location in either ASCII or Unicode where the barcode symbol for the character resides in the font.
The columns ASCII, Char and Unicode are unique to IDAutomation's Code 128 Barcode Fonts. In the columns A, B and C, is the list of characters or functions that the barcode scanner will read for the associated symbol. The table below illustrates the three character sets in columns with the location of the characters. Three different start characters are used in Code 128 barcodes to tell the barcode reader, which character set is being used.
