Postnet & Planet Barcode Specifications

• Using the Postnet barcode option with a font encoder returns text formatted to the Postnet Barcode Fonts.
• Using Uni_Postnet and Uni_Planet with a universal barcode font encoder returns text formatted to the Universal Barcode Font, a single cross-platform font that creates several barcode types.
• Nat_Postnet and Nat_Planet create a "Native" barcode from pure text without requiring the installation of any additional fonts or components. These options exist in the Native Barcode Generators for Access, Crystal Reports, FileMaker, JavaScript and Oracle Reports.
• The Postnet or Planet barcode option in all components and applications will produce an image.
• The product does not create Intelligent Mail barcodes.

The Postnet barcode function may also be used to format data to the Planet Barcode Font in the same way.

When using this function with the Universal Barcode Font, only the XS, S or M size of the font may be used. XS is the normal version, S has the bars narrow by 10% and the M font has the bars narrow by 20%.
