Envelopes

Can Zoho address envelopes and labels and if so can it generate a postal bar code?

If not does anyone know of a program that will do so. I recently bought a new PC with Vista bundles, unfortunately, and it will not accept my Word, Works or Word Perfect. It has its own new Works and the tech said bar codes were dropped because of USPS changes. USPS has its own word processing program but does not reply to questions.

Please help!
