PDF (Portable Document Format) files let you view and print a document as the author designed it, without needing to have the same application or fonts on your computer.

To view or print a PDF file, you need the Adobe Reader, version 5 or later, on your computer. You can download a free copy of the Reader from the Adobe website. See: Download Acrobat

Installation instructions are available from the Adobe website.

Saving PDF files With larger PDF files (say, more than 50KB), it is better to save the file to your computer, and then print from that copy. Using this method, you avoid the risk of having a printing task interupted if your Internet connection fails.

There are several ways to save PDF files onto your computer - use the method that best suits your computer set-up:

you may get a message from a pop-up list - choose the "Save Target as ..." or "Save Link as ..." option

with the PDF file open on your screen, go to "File" and choose "Save As" or

with the PDF file open on your screen, click on the floppy disk icon just above the document, on the left hand side.

Printing PDF files If you have difficulty printing a PDF file, please select 'Use raster graphics' which is found in File/Print/Setup/Properties/Graphics.

PDF filer lar deg vise og printe filer som slik forfatteren/designeren laget det, uten at du trenger de samme fontene eller lignende på din datamaskin. Hvis du skal lagre større PDF filer, er det bedre å lagre filen på datamaskinen, å deretter printe den ut fra den kopien. Med denne metoden slepper du risikoen at internett konatakten kan bryte.

Portable Document Format (PDF) is an open file format created by Adobe Systems in 1993 and is now being prepared for submission as an ISO standard[1]. It is for representing two-dimensional documents in a device independent and resolution independent fixed-layout document format. Each PDF file encapsulates a complete description of a 2D document (and, with the advent of Acrobat 3D, embedded 3D documents) that includes the text, fonts, images, and 2D vector graphics that compose the document. PDF files do not encode information that is specific to the application software, hardware, or operating system used to create or view the document. This feature ensures that a valid PDF will render exactly the same regardless of its origin or destination (but depending on font availability when fonts are not encapsulated in the file).

PDF files are most appropriately used to encode the exact look of a document in a device-independent way. While PDF can describe very simple one page documents, it may also be used for many pages, complex documents that use a variety of fonts, graphics, colors, and images.
