Printing Encrypted Image Data

• With PDF Direct Print, it is possible to print out an encrypted PDF file. The password is registered in

the Printer function via WebImageMonitor or the MFP/LP operation panel, or is set inside

DeskTopBinder (incl. the Function Pallet). When the printer receives the file, the printer language

processing subsystem (PDF interpreter) temporarily stores the file directly to the HDD. Once the file

is recognized as an encrypted PDF file, the password registered in the MFP/LP is compared to the

password sent along with the file. If they do not match, the data itself will not be decrypted correctly,

causing an error to occur and the job and data to be erased. If they do match, the data will be

decrypted correctly. After this, the decrypted data is converted to image data, stored to the HDD

and then follows the normal process described above.

• When Spooling is enabled, the incoming encrypted data is stored directly to the spooling area of

the HDD. Following this, the first page of the data is then sent to the PDF interpreter to be

interpreted.

• It is also possible to set the MFP/LP to prohibit the printing of PDF files. PDF files for which this

setting is used cannot be printed out when received by the MFP/LP, as the MFP/LP resets the job

and deletes the data.

Data Security Considerations

Printing Unencrypted Image Data

• The language processing subsystem only allows data in legal format to be processed. In the event

that illegal data is received, the subsystem will declare an error and cancel the processing session.

• When User Authentication is enabled, the MFP/LP will only accept printing data that contains a

username and password (or User Code in the case of User Code Authentication) that matches

those of a pre-registered user. Any such data is destroyed, preventing the introduction of illegal

data. When the Printer’s authentication mode is set to Simple Authentication, the MFP/LP does not

perform authentication on data sent from users that have been given “Guest” status.
