Hi!

I am not sure if that's really a bug in CoursePresentation (or a feature in iOS). CoursePresentation checks whether the browser reports to support printing in https://github.com/h5p/h5p-course-presentation/blob/33b4c1993c6046fb943386d524bf58cade8def28/src/scripts/printer.js#L19-L22 by checking for a print function being available. It suppose that iOS does not make the print function available inside iframes, so H5P cannot use it. A fix just for this issue would probably mean having to change CoursePresentation and H5P core - so that might take a while.

Cheers,
Oliver

Hi Oliver, thanks for the reply. That makes total sense, and it's not a huge deal for use cases I've come across. I was probably just tripped up because I saw it on one device and not the other, but the explanation makes sense. 

Thanks for the quick response!

Cheers,
