arrange in ordered sets. In printing several copies of a multipage document, if the user checks the Collate box, one complete set of pages will be printed, followed by another set. Otherwise, the required number of copies of page 1 will be printed, followed by page 2, and so on.
to place printed pages in order before they are bound into a book. Some photocopiers have the ability to collate multipage documents automatically.
When printing multiple copies of a document, choose "collate" if you want the pages printed in the correct order and you don't mind taking some extra time; the whole document will be sent to the printer more than once. If you do not choose "collate," you will get all the copies of page 1, followed by all those of page 2, and so on; printing will be faster because the printer will receive each page only once, followed by a command to print it repeatedly.
