another place where I think you'd probably want some "part" of this.

   if (is_scripted) {
     PrintingContextDelegate* printing_context_delegate =
         static_cast<PrintingContextDelegate*>(printing_context_delegate_.get());
     content::WebContents* web_contents =
         printing_context_delegate->GetWebContents();
     TabAndroid* tab =
         web_contents ? TabAndroid::FromWebContents(web_contents) : nullptr;
 
     // Regardless of whether the following call fails or not, the javascript
     // call will return since startPendingPrint will make it return immediately
