2.1.4 Secured Print Jobs

Overview:
Secured Print is the function that a password is provided to the PDL(UFR II and PCL) 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).

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 cop-
ies and finishing information remains.
