POSTNET bar code for envelopes in Word 2002?

[stephebr]

I'm trying to print a POSTNET bar code for an envelope in Word 2002. The
instructions from Word's help say "On the Tools menu, point to Letters and
Mailings, and then click Envelopes and Labels.
Click the Envelopes tab.
If necessary, enter or edit the delivery and return addresses.
Click Options.
Click the Envelope Options tab.
To print a POSTNET bar code that contains U.S. ZIP Code information from the
delivery address, select the Delivery point barcode check box."

Here's the problem. There is no "Delivery point barcode check box" on that
screen.
