The `trick' is to read the introductory documentation.

R-exts.texi has

The recommended procedure to use these is to include the header file
@file{R.h} in your C code by

@example
#include <R.h>
@end example

If you do that, Rprintf *is* defined (via R_ext/Print.h)

That said, I have never seen problems under Windows, so are you doing
that properly (using the correct import library)?
