EN Status Readback Commands 7-37

Note Some HP LaserJet printers support job cancellation. For information

about unsolicited job status during job cancellation, see the “Job

Cancellation” section in Chapter 5.

Example: Using Unsolicited Job Status

This example turns on unsolicited job status so that the spooler can

be notified when the job starts and completely finishes. A job name is

included so that the spooler can match the status information with the

correct job. (The indented lines indicate a job sent to the spooler from

another application.)

@PJL USTATUS JOB = ON <CR><LF>

@PJL JOB NAME = "JOB 14993" <CR><LF>

@PJL ENTER LANGUAGE = PCL <CR><LF>

<ESC>E . . . PCL Job . . . <ESC>E
