The Adobe Acrobat Reader allows you to browse portable document format (PDF) files that have been created by Adobe Acrobat. It also enables you to fill in visually rich, interactive PDF forms. Plug-ins for both Netscape Navigator and Internet Explorer are included and automatically installed. Version 4.0 offers several new features and improvements. Acrobat Reader's integration with Web browsers has been improved, and this version offers faster and more reliable printing to both PCL and Adobe PostScript printers. There is better support for longer and more complex documents. Support for the latest version of the Acrobat file format, Adobe PDF 1.3, has been added, as well as support for all versions of PostScript, including the new PostScript 3. Version 4.0 also has better color handling, including support for ICC profiles, and is compatible with previous versions of Acrobat Reader. Another new feature is the ability to download and install Asian font packs that enable you to view PDF files that contain Chinese, Japanese, and Korean fonts on non-Asian operating systems using Acrobat Reader 4.0.
