Examples associated with printer encryption are described. One example printer includes a data store to store a one-time pad. An encryption module may encrypt a message using the one-time pad. The encryption module also transmits the encrypted message to a trusted device that stores a copy of the one-time pad. A decryption module uses the one-time pad to decrypt a received message form the trusted device. The decryption module also controls the printer to perform an action based on the received message. A refresh module replaces the one-time pad during a service event.

Printer encryption

In various disclosed examples, an identifier is selected from a first set of identifiers, the selected identifier having a representation of at least two different characters. An indication of a difference between the representation of the selected identifier and representations of one or more identifiers from a second set of identifiers is calculated, and the selected identifier is determined to be an eligible identifier if the indication of the difference satisfies a threshold criteria.
