Secured Print Jobs
■ Overview:
Secured Print is the function that a password is provided to the PDL(UFR II and PCL, PS)
print job and it is sent to the device. Then, it is rasterized on the device side, saved in the
image server and output by entering the password from the device's panel. This function is
used when dealing with the documents which you do not want other people to see, such as
confidential documents.
a) Password is provided.
In order to conduct the Secured Print, the printer driver requires the user to enter the
password from GUI. This password is provided to the print job and it is sent to the device.
This function can be conducted by using CPCA protocol(UFR II and PCL, PS).
b) Job execution and pending
PDL print job sent to the device as the Secured Print job is compiled on the job queue like the
normal PDL print job. Then, it is rasterized by PDL interpreter, saved in the image server as
the document image file and becomes pending here. However, all job information, such as
paper supply/output, the number of copies and finishing information remains.
c) Job started by entering the password
If the Secured Print job is pending, the display indicating the pending state appears on the
job status screen of the panel. If you select this job from the panel, you are required to enter
the password. When the password you entered is same as the password provided from the
printer driver, the pending job will be started. When the password is different, the job is treated
as an error, so it is not started and it remains in the pending state. Entering the password to
start the job cannot be executed before the Secured Print job transfers to the pending state.
d) Output
The started Secured Print job is output to the printer engine with the top priority. This top
priority means that if the jobs can be changed in priority order, the Secured Print job can
be prioritized. This job is proceeded according to all job information specified by the printer
driver, etc., such as paper supply/output, the number of copies and finishing information.
When the processing is completed and all documents are output, the documents and job
information stored in the image server are deleted.
e) Operations for Secured Print jobs
Like other print jobs, Secured Print jobs can be deleted, interrupted, restarted and promoted
by operating from the status screen of the print job. Regarding these operations, the device
side does not distinguish from operations of the normal PDL job. That is, the password entry
is required only when the job is output. If you interrupt or restart the job during outputting, the
password setting and matching are not conducted.
f) Automatically delete of Secured Print Jobs
When Secured Print Job is continuing being suspended for a long time, apparatus deletes a
job automatically.
There are options for automatic job deletion time -- 1, 2, 3, 6, 12, and 24 hours. With a view of
security and memory usage, no option longer than 1 day is available. The elapsed time starts
after all the processes for the PDL data and the rendering for all the image data, for which
Secured Print is specified, are finished.
g) Specifications and Limitations on Secured Print Jobs
The limitations on Secured Print jobs are listed as follows.
• Once data of a Secured Print job is printed, it is immediately deleted and cannot be printed
any more.
• If the power for the controller is shut down, unprinted data of a Secured Print job is deleted
from the printer.
• All the job information, represented by the paper source and output information, information
of the number of copies, and finishing information, cannot be changed on the printer.
• If the entire raster information for a Secured Print job cannot be stored in the image server
(hard disk drive) due to insufficient memory, the job results in an error, to be deleted.
• Up to 50 Secured Print jobs of image data being rendered and left unprinted can be stored.
