Hi Mike,<br><br>For operation (3) DeregisterOutputDevice, I was thinking of the case<br>where a running service (Print in the near term) crashes (and this is<br>noticed by System Service, let us hope). If DeregisterOutputDevice<br>is (redundantly) supported by the System Service, then an Administrator<br>could do the cleanup for the Infrastructure Printer (who might queue<br>jobs).<br><br>Or, I'm crazy, and the System Service would automatically do this<br>cleanup internally and no external operation needs to be exposed.<br>But that risks a Deregister when the crashed service can be<br>successfully automatically restarted by the System Service after<br>a brief interval of unavailability. <br><br>I have mixed feelings about the reliability (and advisability) of <br>automatic recovery by the System Service for crashed or stalled <br>Job Services.<br><br>WDYT?<br><br>Cheers,<br>- Ira<br><br clear="all"><div><div class="gmail_signature"><div dir="ltr">Ira McDonald (Musician / Software Architect)<br>Co-Chair - TCG Trusted Mobility Solutions WG<br>Chair - Linux Foundation Open Printing WG<br>Secretary - IEEE-ISTO Printer Working Group<br>Co-Chair - IEEE-ISTO PWG Internet Printing Protocol WG<br>IETF Designated Expert - IPP & Printer MIB<br>Blue Roof Music / High North Inc<br><a style="color:rgb(51,51,255)" href="http://sites.google.com/site/blueroofmusic" target="_blank">http://sites.google.com/site/blueroofmusic</a><br><a style="color:rgb(102,0,204)" href="http://sites.google.com/site/highnorthinc" target="_blank">http://sites.google.com/site/highnorthinc</a><br>mailto: <a href="mailto:blueroofmusic@gmail.com" target="_blank">blueroofmusic@gmail.com</a><br>Winter 579 Park Place Saline, MI 48176 734-944-0094<br>Summer PO Box 221 Grand Marais, MI 49839 906-494-2434<br><br><div style="display:inline"></div><div style="display:inline"></div><div style="display:inline"></div><div></div><div></div><div></div><div></div></div></div></div>

</span>I'm not sure this needs to be in the system service, we already have it in the base Print service (and thus any of the other services).<br>
