Vista - Use WinFX (FlowDocumentReader etc.) in non-GUI application?

I am interested to use the document-formatting capabilities of
FlowDocumentReader etc. for a proposed server application, which will
not have a graphical user interface. Is this feasible?

The idea would be to use the FlowDocumentReader to layout some text,
on a programmatically-set page layout. We'd then print it (to XPS,
maybe), without ever displaying it on a screen.

I'm new to .Net, but experienced in programming. Any hints anyone can
give on approaches to take, Web sites to visit, maybe even books to
buy?
