Unless your printer can print on 12-by-12-inch paper, you will encounter some problems printing full-size digital scrapbooking pages. One solution is to work at 8.5-by-11-inch size and assemble the result onto 12-by-12 cardstock. For example, you might print an image incorporating photos, photo mats, and some of embellishments on an 8.5-by-11-inch sheet and create a page title on another sheet of this size. You then could assemble the parts onto 12-by-12 cardstock. This way, you could enjoy the benefits of digital scrapbooking combined with some traditional paper techniques.
If you have a printer capable of printing at 12 by 12 inches or larger, you can print your pages easily and incorporate them into your regular album.
