I have a request to provide CASS certificated addresses on a PDF document. This involves using a certified mailing address, and needs to be printed using the barcode.
How can I generate such a barcode? Might exists PHP libraries that already does this?
The USPS has libraries and helper code you can download for all major platforms. They don't have a PHP class, but you could
exec
orsystem
out to the OS to generate the code.
