Printer-friendly is a term used on the Internet to describe a version of a web page formatted for printing. Normally, web pages include information and navigation content that is only useful while browsing the website. Printer-friendly pages are designed to fit on an 8.5"x11" or A4 sheet (see paper sizes) and include only the content (plain text and images) of the page, along with source information. Inline hyperlinks become ordinary text, links on the margins may or may not be shown. Additionally link target URLs may be shown. Navigation tools such as on-screen menus are not included.
Printer-friendly pages are used not only for printing onto paper, but also for storage on machine-readable media such as hard drives, floppy discs or CD-ROMs. They are usually accessed through a link on the standard page. Often the link will be indicated by a printer icon.
