Businesses use barcodes extensively, particularly for inventory control. Barcodes can be used to identify forms, but they are often printed on adhesive paper to create labels for inventory purposes.
LiveCycle Designer ES supports two types of barcodes:
Only use when the form is being printed directly to the printer from the server. Because a printer is required to print them, LiveCycle Designer ES uses a placeholder to represent hardware barcodes in the form.
Can be drawn by LiveCycle Designer ES and are visible in Acrobat and Adobe Reader. They can be printed on any general-purpose printer.
LiveCycle Designer ES provides a variety of barcode formats that you can work with. The supported barcode formats are listed in the Barcodes category of the Object Library palette. If you use a barcode that requires a specific type of printer, LiveCycle Designer ES represents the barcode as a shaded rectangle in the form.

After you add a barcode to the form design, you can manipulate the object’s properties in the Field, Value, and Binding tabs of the Object palette. You can define these properties:
