Portable Document Format (PDF)
For loading, reading and printing files in PDF format you need suitable software, e.g. Adobe Reader. Adobe PDF is a universal file format that preserves all of the fonts, formatting, colors, and graphics of any source document, regardless of the application and platform used to create it. PDF files are compact and can be shared, viewed, navigated, and printed exactly as intended by anyone with the free Adobe Reader. The latest version is available for free from the Internet.
