The Mac Barcode Company of Chicago has introduced Barcode Express -- a one-window, two-step tool for creating UPC, EAN, ISBN or other sorts of barcodes and exporting them in either bitmap or vector formats ready for printing. The program features a "live preview" as the user types, always able to see exactly how the barcode will appear at any moment. It does not generate the values that go into a barcode, but gives those with that information a drop-dead easy way to make a standards-conforming barcode.
