Code 128

Updated: 12/31/2022 by Computer Hope

Code 128 is a symbology (font) in barcode technology that uses all 128 characters of the ASCII (American Standard Code for Information Interchange) table, which allows an alphanumeric barcode. This symbology is used by downloading the font files, so that it may be translated into printer code, allowing the printer to print barcodes correctly. However, Code 128 is not necessary for all printers, as specialized barcode printers have different barcode symbologies (fonts) built-in.
