HP PCL/PJL reference - Printer Job Language Technical Reference Manual

EN Job Separation Commands 5-9
• Terminates the non-printing mode (enabled by using the
START/END options). The non-printing mode, if enabled by
the last JOB command, only applies to the previously received
data, and does not effect any future pages until another JOB
command enables the non-printing mode again.
Effect on Unsolicited Job Status
When the printer receives this command, it returns unsolicited job
status information, if enabled, when the last page of the job exits the
printer and is in the output tray. The EOJ command resets the page
number associated with unsolicited page status. Resetting the page
count associated with unsolicited page status only affects future
pages. Pages already processed, but not yet printed, are not affected.
