Abstract
The present invention relates to a system and method of securing a printer. The system includes a printer, having a nontransitory storage medium, configured to: store a password encrypted with a first encryption scheme; re-encrypt the stored password with a second encryption scheme upon a predetermined interval/event; receive a data stream from a host computer; determine whether the received data stream contains the password encrypted with the second encryption scheme; and print a document upon determining that the data stream contains the password encrypted with the second encryption scheme.
