Is the type too small? Or too large?

If your browser supports text resizing (eg, recent versions of Internet Explorer, Firefox or Opera), you can alter the size of the text on the site to suit your preference. If you are using Microsoft Internet Explorer, go to the View menu at the top of your screen, select Text size, then choose to view with larger or smaller type. For other browsers, consult the browser Help for details on how to resize the text.

Print formatting

Content on the site has been created in a way to allow printing only of the content you require. This means that the printed pages will not contain elements such as site navigation and have been optimised for best readability.

Long documents are sometimes best printed using the Adobe Acrobat (PDF) format which is available on the title page of most key documents. To view and print PDF files you will need Adobe Acrobat Reader.
