Barcode Writer in Pure Postscript implements the printing of many barcode formats entirely within level 2 PostScript, so that the process of converting the input string into the printed output is performed by the printer itself. This avoids the need to re-implement the barcode generation process whenever your language needs change. The project supports most major barcode formats including EAN-13, EAN-8, UPC-A, UPC-E, ISBN, Code 128 (A, B, and C), Code 39, Interleaved 2 of 5, Postnet, Code 2 of 5, and Codabar.
