EN Job Management 10-5
HP LaserJet 8500 Printer
The HP LaserJet 8500 printer implements job management in a
different way than the HP LaserJet 8100 printer. For this printer, only
the HOLD = JOB option is supported for the HOLD command. The
HOLDTYPE and HOLDKEY variables are not supported. (See the
descriptions of the HOLD, JOBNAME and USERNAME variables for
more information about their limitations.)
The printer's Proof and Print feature allows the user a fast and easy
way to proof one copy of the job, then quickly print any remaining
copies without waiting for data transmission or processing time for the
subsequent copies. Using the printer's control panel buttons,
selecting the PROOF AND PRINT menu item displays the JOB
NAME and USER NAME on the control panel display. The ITEM keys
can then be used to scroll through the list of printable jobs currently
on the disk. The VALUE keys can be used to change the number of
copies selected. Choosing SELECT launches the job. Once the job is
launched, the number of copies cannot be changed.
When all copies of the job have been completely printed, the file is
removed from the disk. Pressing CANCEL JOB while the job is
printing or when the JOBNAME is displayed on the control panel
cancels printing and deletes the file from the disk.
Turning the printer power off or the occurrence of non-correctable
errors causes the printer to save the file on the printer's disk. The
number of copies completed will not be updated from the original
number if the job does not complete without error. If all copies of the
Proof and Print files have not been printed, the job will remain on the
disk indefinitely until the user specifically deletes the job. The user
can delete the job using the control panel by selecting the job and
setting the number of copies to zero. Alternatively they can select the
job and press the Job Cancel key.
