What is a PDF file?
A PDF file is a self-contained cross-platform document. In plain language, it is a file that will look the same on the screen and in print, regardless of what kind of computer or printer someone is using and regardless of what software package was originally used to create it.
Although they contain the complete formatting of the original document, including fonts and images, PDF files are highly compressed, allowing complex information to be downloaded efficiently.
How to View PDF Files
Once the Acrobat Reader software is properly installed, you just need to click on a link to a .pdf file and it will be loaded for viewing on your computer.
How to Print PDF Files
When printing Adobe Acrobat PDF files from within your web browser, do not use the web browser print facility. Instead, use the print button at the left end of the special Adobe Acrobat application tool bar, which appears immediately above the viewing window.
