You can also scale an entire document when you print it, without changing the objects in the document, by specifying a scaling factor in the Print dialog box.
Select a method to scale by:
Set the origin of scaling. By default the origin is the center of the object.
Scales the object by its area.
Scales the object by its perimeter.
Enter the percentage of scaling or an absolute value. If you choose to scale by absolute value, you can select the unit of measure.
Select this checkbox to maintain the proportion between an object’s pen size and the overall size of the object.
