This is no longer used. It's weird how the compiler doesn't catch this.

-    if (value->GetString(printing::kSettingSavePath, &save_path))
-      save_path_.reset(new base::FilePath(save_path));
     std::string buffer;
     if (value->GetString(printing::kSettingAppState, &buffer))
       printer_app_state_.reset(new std::string(buffer));
   }
 }
 
 void StickySettings::RegisterProfilePrefs(
     user_prefs::PrefRegistrySyncable* registry) {
   registry->RegisterDictionaryPref(prefs::kPrintPreviewStickySettings);
 }
 
 std::string* StickySettings::printer_app_state() {
   return printer_app_state_.get();
 }
 
-base::FilePath* StickySettings::save_path() {

-}
