Can you explain how can i print my envelopes with Word? I understand that i can use Microsoft Word not only to print my letter, but also to create some professional looking envelopes for my letter. That said, i need to send an official letter to an university admissions office, so it has to be printed. I typically use e-mail for communication with my friends and colleagues in our marketing business team.
