DocPrintJob to monitor the status of attribute changes associated with the print job.
DocPrintJob to monitor the status of the printer job.
PrintService to monitor the status of the print service.
PrintJobEvent encapsulates common events a print job reports to let a listener know of progress in the processing of the
DocPrintJob.
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.
