The main purpose of this paper is to demonstrate how to create a PDF writer by using Virtual Printer Method, which gives your applications an ability to generate PDF file through simply "printing". I am pretty sure there are many PDF writers using the same technique, saying PrimoPDF (http://www.primopdf.com/ ). However you probably wish to create your own PDF writer in some day. I here give an example to uncover the whole process of creating such kind of PDF writer.
