<p class="MsoNormal">Currently there is no notion of a default service in (standard) IPP or the SM. CUPS has a pair of extension operations for getting and setting the default printer (and at one point even allowed a server to advertise it as a sort-of "default
network printer" that clients could prefer, with the usual security caveats), however those operations are now rarely used as mobile computing has made the notion of a default printer location-specific.<o:p></o:p></p>
