Hello! 
I know it is difficult to keep a reference book up to date, but I’ve had internet problems recently and I could’nt check the docs when I needed to [-http://www.openframeworks.cc/documentation ], and it got me thinking if there is a printable reference doc, or maybe one that is easier to print than the one I just mentioned.
Or maybe some other type of suggestion.
Anyways, thank you. 
there is currently no single-page or printable documentation. there is some work going towards doxygen-generated-documentation, which should eventually be able to provide a single “manual” pdf or similar.
Nice!!! thanks for the info. I’m looking forward to it.
Hi,
I’ve got similar problem with you. I’ve just downloaded a PDF file of OpenFrameworks documentation by Arturo Castro. There is also a translated one page manual from Japanese openframeworks documentation. Please visit my small weblog. You can find the PDF file at the bottom side of this page:

I hope it helps!
