Today we created a small tool merging all parts of the manual together, so now there is a single file version of manual - this means it must be possible to print it as well. But I don't recommend you to do this right now - few chapters there aren't written yet; moreover, there are no special styles for printing. So it's really better to wait for few days; moreover, shortly we'll build its PDF version ideal for printing.
P.S. If you will decide to print it, do this in Internet Explorer (print with background colors) - by my impression it must do this better than other tested browsers (I tried this in Firefox 3 and Google Chrome).
