The package is meant to solve most needs in barcode creation with a conventional printer. It can create printouts for the conventional product tagging standards: UPC-A, UPC-E, EAN-13, EAN-8, ISBN, as well as a few other formats. Output is generated as either Postscript or Encapsulated Postscript (other back-ends may be added if needed). The package is released as both a library and a command-line frontend, so that you can include barcode-generation into your application.
