The printer driver tells Word which way the envelope should be loaded into the printer, and this information is displayed in the Printing Options tab of the Envelope Options dialog box.

1. The feed method determines the position of the envelope (right, middle, left) and whether the long or short edge is being fed into the printer.

2. The envelope can be face up or face down. The face is the side that the address is printed on.

3. If the envelope is fed short edge first, the envelope may need to be rotated to prevent the text from appearing upside down on the face of the envelope.
