ABSTRACT:
A printer includes a local non-volatile memory for storing at least one print job; and a control system, including at least one processor and an encryption algorithm. When a print job is sent to the printer and designated for printing at a later time, the print job is assigned a key identification number (KEY) and then encrypted by the processor based on the encryption algorithm and the KEY. The encrypted print job is then stored in the local non-volatile memory as a secured print job, while the KEY associated with the encrypted print job is erased from the printer.
