PDF Emerges From PostScript

So what are the major differences between PostScript and PDF files?

• PDF files are smaller than PostScript files. Smaller files are easier to send, store and manage.

• PDF files are more reliable than PostScript files—but, only if they are created properly.

• PDF files can include all of the resources for a document. This is the greatest strength. Instead of a collection of resources along with an application file, you get one file that can be viewed in a standardized "viewer."
