<h3>e715. Listening for Print Job Attribute Changes</h3>
Status changes that are common to all print jobs are delivered through
a print job listener; see <a href="../javax.print.event/JobDone.html" class="eglink"><b>e714</b> Listening for Print Job Status Changes</a>.
However, if a print service supports a status that is not supported by
the print job listener (e.g., <code>JobMediaSheetsCompleted</code>), it
delivers status changes through a print job
attribute listener.
<pre> // Create the print job
DocPrintJob job = <font color="#0066ff"><i>service</i></font>.createPrintJob();
PrintJobAttributeSet set = new HashPrintJobAttributeSet(job.getAttributes());
set.add(new JobMediaSheetsCompleted(0));
job.addPrintJobAttributeListener(new MyPrintJobAttributeListener(), set);
class MyPrintJobAttributeListener implements PrintJobAttributeListener {
public void attributeUpdate(PrintJobAttributeEvent pjae) {
// Get the set of attributes that have changed
Attribute[] attrs = pjae.getAttributes().toArray();
for (int i=0; i<attrs.length; i++) {
String attrName = attrs[i].getName();
String attrValue = attrs[i].toString();
<font color="#0066ff"><i>process</i></font>(pjae, attrName, attrValue);
}
}
}
</pre>
