postnet - package for producing postnet barcodes for PCL 5 printers
use postnet;
print 'The postnet barcode for 49104 is ' . pnpcl( '49104' );
This package produces the USPS postnet barcode for standard 5-digit zipcodes
and zip+4 codes. If the zip code passed is not 5, 9, or 10 characters in
length or contains characters other than 0-9 and the '-', pnpcl returns undef.

Currently this package only produces PCL 5 code. It will not produce postnet
barcodes for dot-matrix or PCL3 printers.
This package is based upon C routines published in the C Gazette,
Volume 5, Number 2 by Andrew Binstock.
