Hi,
Sorry for the delay. We have confirmed this to be a Chrome bug:
https://code.google.com/p/chromium/issues/detail?id=83341The problem seems to that Chrome won't print any plug-in loaded through NPAPI (Netscape Plug-in API). Chrome uses its own PDF implementation that uses Pepper Plugin API, which does support printing. Currently EO.WebBrowser does not support Pepper Plugin API. So as for now it is unable to print plug-ins. We will see if we can add Pepper Plugin support.
Thanks!
