novaPDF SDK sends a request to create the PDF files to the printer driver that gets installed with the package, novaPDF for SDK. By default, if novaPDF SDK is unregistered, each page from the generated PDF file will contain a footer notice (that says the application is not registered). After you purchase a license and register novaPDF SDK, that footer notice won't be included in the generated PDF files.
When integrating novaPDF SDK in a 32bit application that will be distributed on Windows x64 systems too, you have to take into account some aspects regarding the default behavior of our installer. One of these is the novaPDF installer that contains both 32 bit and 64 bit versions of the novaPDF driver and of the COM interface. Because of its built-in automatic detection, when installing novaPDF on Windows x64 computers (via your application), the 64bit version of the driver and COM interface are installed (and not the 32bit version).
