mirror margins

[MB]

why are mirror margins used??? what does it do??

 

[Bill Foley]

For printing out your document as double-sided, or if you plan on making
double-sided copies. If you didn't use mirror margins the inside on the
front page would have "x" margin and the outside of the back page would have
"x" margin. It would look sort of messed up not to mention that you might
not be able to see part of a page if you are binding or hole-punching the
document. This, in addition to using gutters, make for a good two-sided
bound document.

 

[Suzanne S. Barnhill]

Mirror margins doesn't do anything if your left and right margin are the
same, but if you are allowing extra space for binding (either with a larger
margin or with a gutter) on the inside of a page and are duplexing (printing
front and back), then "mirror margins" converts your Left and Right margins
to Inside and Outside so that the larger margin will alternate left and
right as appropriate for binding.
