In a Windows environment
The front and back covers and specified pages of a document are printed on paper that is different from the other pages.
Use this function when you wish to print the front and back covers on heavy paper, or insert colored paper or a different paper type at specified pages.
As necessary, paper can be inserted as insertion sheets where nothing is printed.
In a Macintosh environment
The front and back covers are printed using paper that is different from the other pages. This function can be used, for example, when you want to print only the front cover and last page on thick paper.
In a Macintosh environment, this function is only available when using Mac OS 9, Mac OS X 10.4.11, 10.5 to 10.5.8, or 10.6 to 10.6.2.
