How to Create an Envelope for Your Letter in Word 2013
Type the return address on the envelope.
It may not be obvious on the screen, but the first page of your letter is now an envelope. When you’re ready to print the letter, the envelope is printed first and then the letter. All you have to do is stuff the letter into the envelope and seal it and then apply the increasingly costly postage.
Most printers prompt you to manually enter envelopes if that’s what they want you to do. After doing so, you may have to press the Ready, On-line, or Select button for the printer to continue.
When typing an address, use soft returns to break up the lines: Press Shift+Enter at the end of a line. That keeps the address tight.
Check the envelope as you insert it into your printer to ensure that you didn’t address its backside or put the address on upside down.
If you have trouble remembering which way the envelope feeds into your printer, draw a picture of the proper way and tape it to the top of your printer for reference.
