From the developer: "The Code 128 Font Advantage Package is much more than a few bar code fonts. This barcode package contains several font versions in many font formats (including TrueType, PostScript, BDF, FON and PCL) for Windows, Macintosh, UNIX and a variety of other operating systems. You also receive font tools, macros (for Microsoft Access, Word mail-merge and Excel) and source code in Visual Basic, C and Java to help you integrate barcodes into your applications."
