Is there any specific reason for adding this check here (this code is executed
at the end of the printing workflow) rather than adding the code at the very
beginning of the printing workflow (like when the user press ctrl+P etc.,)?

   printing_context_.reset(PrintingContext::Create(
       g_browser_process->GetApplicationLocale()));

   // cancels printing or in the case of print preview, the worker is destroyed
   // on the I/O thread.
