G'day Ladyhicks,
If it fits on one page in word, then it will generally Print
on one Page - however in your case some of the text
is clearly in a region on the paper that is "non-printing"
for your particular printer.
You need to move the text upward by reducing the
Top Margin
in
File>Page Setup....
If that is not possible ('cos you already done did that),
then (at the cost of appearance) try:
reducing both Left and Right Margins
in
File>Page Setup...
to get more text on each line
reducing the font size
EITHER
for the whole page
OR
for points (paragraphs) that you consider to be
marginally less important.
AND/OR
reducing the line spacing in
Format>Paragraph
set the line spacing to "exactly" xx, where xx is
1 or two points less that the font size.
