Здравствуйте.
Нашёл библиотеку для создания файлов .pdf здесь.
Привожу цитату из лицензии:

- The PDF4NET library is licensed per developer. One license can be used on multiple computers as long as it is used by the same developer, and it can not be used concurently or shared by other developers.
- When using the PDF4NET library for desktop development (native Windows applications), the library is licensed royalty free. You pay to use during the development time to create your final product. You do not need to pay any other fees when you distribute the PDF4NET library with your final product.
— When using the PDF4NET library for server-side development (ASP.NET web applications), the library is licensed deployment free. You pay to used during the development time to create your final product. You do not need to pay any other fees when you deploy the PDF4NET library along with your final product on other servers.
— This license does NOT ALLOW you to distribute the PDF4NET library for use in development. This requires an OEM distribution license. If you want to do so, please contact us.

Так вот чё-то не догоняю если я пишу native Windows applications, то лицензия платная или нет
