C# Print/PDF creation class

C# Print/PDF creation class We need a class that can be added to an existing c# solution and gives us the upertunity to print pages or create a PDF document. This class will be used in a windows c# form application and on a c# .net website. The info (name, street, city and an array of orders ....) that has to be put on the document is stored in a database. Since we want to use different documents, and different layouts we want to store the document makeup also in the DataBase. The basic idea is to create XML based templates that store information about page looks, and to load these templates, fill them with data and print. A template manager/xml editor must be available or programmed. If you can solve this with an existing solution like Stampa or iTextcharp we agree but please let us know and mention it in your RAC bid.
