I would like to say, Force.com lets you easily generate PDFs on the fly, based on a simple attribute of a Visualforce page. You can use this functionality for many purposes: for example, you can generate professional looking invoices or quotations. Of course, you can also email, store, print or display the PDFs.
The key to professional looking PDF is styling, and you can accomplish the styling of generated PDFs by modifying the cascading style sheets (CSS) of the page. This article will provide an overview of CSS styling to improve presentation, support pagination and the ability to add page numbering to any PDF document. We will use the free Simple Quotes app, available on the Force.com AppExchange to demonstrate the techniques discussed with a common, real world example.
Best and advance
