We are looking for a virtual printer driver SDK that enables us to build our own PDF printer driver. I only found some information on a few internet pages, but there doesn’t seem to be a product page on your website. Why is that?
Did you see the following post: https://groups.google.com/d/topic/pdfnet-sdk/10sZiNt-AeE/discussion ?
Virtual Printer Driver SDK is essentailly source code for a sample driver (referenced in the above email) which is using PDFNet for conversion to PDF (and or other formats).
