Why does the "GDI Brochure" option generate two different pages?
The Brochure is meant to be a two-sided, tri-fold brochure. Print each brochure page on the front and back of a single piece of paper. Many printers have an option called "Duplex Printing" that will automatically print to both sides of a sheet of paper. If your printer does not have this feature, print just one side of the brochure, place the printed paper back into the printer feed tray, and print the second page. Refer to your printer's manual for details on how to orient the paper properly, otherwise this task may require a couple of tries to perfect.
