It would appear that ItemNew events aren't being emitted, as the self._printer_added_cb call-back is never invoked. I've tested this code in an external python script with sugar-shell, and it is working perfectly.<br> <br>I am sure that I am missing something silly that is specfic to the sugar environment, so I am curious if anyone has any ideas as to why it isn't working.<br><br>Thanks in advance for any help.<br><br>--<br>Justin Gallardo<br> </div>
