About preparing Microsoft Word letters using QuickBooks data
The Envelope Options window appears when you choose to print letters and envelopes
together or just envelopes.
Click the envelope size from the drop-down list.
Select the Print return address checkbox to print your own
address and edit your return address.
Select the checkbox if you are mailing letters within the U.S. and want
a delivery point barcode.
Note: The destination printer is shown at the bottom of this window.
Be sure that your default printer is set to the appropriate machine. If
it isn't, click Cancel and change your default printer selection so
that your envelopes print on the printer of your choice.
