Abstract:
Examples associated with printer firmware encryption are described. One example printer includes a base firmware module. The base firmware module controls a base function of the printer. The printer also includes a first encrypted firmware module that modifies a first function of the printer. The first encrypted module is inactive until decrypted. A firmware decryption module decrypts the first encrypted module upon receiving a first encryption key.
