In contrast, the appellants' interface allows a user to apply non-persistent
formatting changes to individual pages or groups of pages of an electronic document
without altering the original electronic document. (Appeal Br. at 3-4.) When the user
selects the print operation in an application program, the interface displays a window
showing thumbnail images of the pages of the electronic document so that he can
select a page or group of pages within the document. When a page or group of pages
is selected, pop-up menus appear enabling the user to select optional special formatting
operations to apply to the selected page or group of pages. (Id. at 4.)
The appellants' interface applies the formatting changes to a copy of the data file
comprising the electronic document passed to the interface by the application program
with which it was created. The original electronic document is unaltered and can be
used to compose other printed output without the need to remove formatting changes
made for an earlier printing. (Id.)
