FILE, PAGE SETUP,
Change the Top and Bottom margins from the 1" default.
Reduce the margins to 0.5 for example. Printers have a minimum margin which is defined by the printer driver.
If you are trying to get more information on the page, you can also try to reduce the Left and Right margins, and if you are desperate, you can reduce the font size ( not on this menu though). [ highlight the text, and right click, FONT ]
You can also change from Protrait, to Landscape if your document is too wide to fit on 8.5" width.
You can change from 8.5" x 11" to 11" width to 8.5" height.
Try the FILE, PRINT PREVIEW feature, to see how it will look before you print.
