I would like to generate (and then print or save) big XPS documents (>400 pages) from my WPF application. We have some large amount of in-memory data that needs to be written to XPS.

How can this be done without getting an OutOfMemoryException? Is there a way I can write the document in chunks? How is this usually done? Should I not be using XPS for large files in the first place?

The root cause of the OutOfMemoryException seems to be the creation of the huge FlowDocument. I am creating the full FlowDocument and then sending it to the XPS document writer. Is this the wrong approach?
