Word == how to del. page

Do you want to del the page forever?
1- Hightlight the whole content of the page, 「Backspace」,
2- or 「Edit」「Delete」

If you want to hide up the page when printing:
1- 「File」「Print」「Alt + G」,
2- Type your desired page no. that you want to print, then the 「delete」page will be omitted when printing.

Hoping that can help!
