Why it is worth using instead of handwriting
Printing directly onto an envelope produces a cleaner, more legible result than handwriting, and it is far faster for anyone sending more than a handful of pieces of mail.
Check your printer's envelope feed before printing
Most printers require an envelope to be loaded in a specific orientation, often face-up or face-down depending on the model, and the Envelopes dialog in Word shows a small feed diagram to match. Printing a single test envelope first avoids wasting a stack of real ones.
Frequently Asked Questions
Can I save this envelope address for reuse later?
Word does not save individual envelope addresses as a list on its own, but you can add an envelope with a saved address to the same document, or use Mail Merge if you need to print many different addresses at once.
What if I do not know the exact envelope size?
Common sizes like Size 10, a standard US business envelope, are listed by name in the Options dialog, so you can usually match by the label printed on the envelope box rather than measuring it yourself.
