in excel; page size is adjusing, not print size on page.
 

I apparently have done something that when I go to print, the area which is
printed on a page does not change, only the size of the page. ie; in the
print command, I scale the size to 75%, but it reduces the actual page, does
not reduce the printed text to print more on a page. So if I put in 10%, the
worksheet displayed on the screen is 10% of the actual size vs. putting more
data on a printed page. Help.
What did I change accidentally to cause this?
