Our PDF417 bar code fonts allow printing of high density PDF417 barcodes from any system with a Java 1.1 VM or a 32 bit Microsoft Windows system with TrueType, BDF, FON, PCL laserjet soft fonts and PostScript fonts. Visual Basic source code, a Java Class Library, an ActiveX DLL and MS Office Macros are provided for the encoder. Hundreds of text characters and binary data can be stored securely and inexpensively with the PDF417 symbology. Using Reed Solomon error correction, the printed PDF417 symbol can also withstand damage without causing loss of data. This high level of error correction is far more advanced than one dimensional barcodes with check digits..
