Use this technique for reducing or enlarging 
 the printed size of the music itself, including text and expressions (without 
 changing the actual page size). You must be in Page View to reduce or 
 enlarge a page.
        
        
            - Click the Resize tool   . .
- Click the upper-left corner of the first page 
 you want to resize. Or, CONTROL+click and choose Resize Page. The Resize Page dialog box appears.
- Enter the reduction or enlargement percentage. 
 Click Hold Margins, too, unless you want the entire printed page 
 to shrink (or grow) proportionally. (See Resize 
 Staff System dialog box for details.)
- Specify the pages you want to resize.
- Click OK. As always, whenever 
 you perform an operation that changes the measure widths, you should 
 update the measure layout.
- Choose Utilities > Update Layout.
