print driver that prints to a PDF file

I want to make a print driver that prints to a PDF file , what will be the logic or where to start any links or books????

I don't think you will be making a driver in C#, I would say start by doing a google search on print drivers, maybe you can find something open source. Once you have the print driver part done the PDF creation is pretty easy.

You could check out the existing PDF printer driver: http://sourceforge.net/projects/pdfcreator/
