This block is disabled with a #if 0 in webview. I did't see a special flag used
in the code to check for webview builds. Would finding/adding something to ifdef
this out be better that such a boolean?

I think this logic is chrome only. Webview cannot get print settings from user
since it does not have a UI.  we will need to use a delegate for this, which
webview will not implement.

                                 is_scripted)) {
     DidFinishPrinting(OK);  // Release resources and fail silently.
