There is no need to re-engineer host applications if you want to use barcodes. The EscapeE barcode plug-in will work with any PCL/HPGL print file. Just mark-up the fields containing the barcode data and EscapeE will rewrite the document complete with the barcode ready for printing.
The example shows how the two dimensional barcode PDF417 is used in a medical record card application. PDF417 provides very dense encoding of large amounts of free text. It is used in applications where the data is not strictly encoded (like UPC or BPO) to avoid transcription errors in narrative or comment data. PDF417 is very robust - it can even be scanned after faxing.
All the text on the record card is encoded in the PDF417 2D barcode. The barcode is produced in a location relative to the encoded field or page corners. The barcode can be rotated.
If required, the encoded text can be removed from the completed document to protect sensitive data.
