Job Cancellation HP LaserJet 2100 series, 4000 series, 4500 series, 5000 series, 8000 series, 8100 series, 8500 series, 5, 5M, 5Si, 5SiMx printers and the LaserJet 5Si Mopier support job cancellation using the printer control panel. When a PJL print job is started using the PJL JOB command as described in this chapter, the following PJL information can be obtained from the printer: • Start of job notification • End of job notification • Job cancellation unsolicited status Each of these pieces of information is described below. Start of Job Notification If unsolicited job status is enabled when the printer begins processing the PJL job, the printer responds to the PJL JOB command with an @PJL USTATUS JOB START response. If job ID reporting is enabled by sending @PJL SET JOBID=ON, the printer response includes a job ID number that is associated with the job name supplied in the JOB command. For example, if the printer receives the following command: @PJL JOB NAME = "job name" If unsolicited job status and job ID reporting are enabled, the printer would generate an ID number (such as 346) and respond with: @PJL USTATUS JOB START NAME="job name" ID=346 The printer-generated ID number can range in value from 0 to 32767. Job ID numbers are unique until they roll over to zero or until the printer power is cycled (at which time the ID defaults to 0). EN Job Separation Commands 5-13
