>Does anyone know how to configure Acrobat PDFWriter printer driver to embed a barcode font into the generated PDF?

Barcode fonts are just that - fonts. Simply create your layout with a field using the required barcode font; in general, it's preferable to use a 3:1 font size ratio for your output; check the compliance requirements for the people who have to accept the barcode. It's also important to select the correct barcode type; there are several standards used for barcoding, and they differ significantly.
