javax.print.event contains event classes and listener interfaces. They may be used to monitor both print services (such as printers going on-line & off-line), and the progress of a specific print job.
Please note: In the javax.print APIs, a null reference parameter to methods is incorrect unless explicitly documented on the method as having a meaningful interpretation. Usage to the contrary is incorrect coding and may result in a run time exception either immediately or at some later time. IllegalArgumentException and NullPointerException are examples of typical and acceptable run time exceptions for such cases.
