Abstract: A replaceable item for a host device, such as a print substance cartridge for a printing device, stores multiple identities. For each identity, the replaceable item stores multiple authentication values, or passwords. The replaceable item selects an identity, and in response to a request for an authentication value from the host device, sends the requested authentication value for the selected identity.

Abstract: Examples associated with printer authentication are described. One example print container includes a space for a supply of print material and an interface for delivering the print material to a printer to which the print container is connected. An authentication module provides an authentication signal to a decrypted module embedded in firmware of the printer. The decrypted firmware module is kept in an encrypted state until decrypted by a decryption module embedded in the firmware of the printer. The decrypted module is decrypted after the decryption module receives a decryption key after release of the printer.

Abstract: A communicating print component a print head comprising a number of memory bits and a single lane analog bus conductively coupling the number of memory bits to a pad located on the exterior of the print head. The pad is to transmit an electrical signal from the number of memory bits, wherein the electrical signal indicates a combination of all selected bits of the number of memory bits.

Abstract: A fluid ejection controller interface includes input logic to receive control data packets and a first clock signal, each control data packet including a set of primitive data bits and a set of random bits, wherein the input logic identifies the random bits in the received control data packets to facilitate the creation of modified control data packets. The fluid ejection controller interface includes a clock signal generator to generate a second clock signal that is different than the first clock signal, and output logic to receive the modified control data packets, and output the modified control data packets to a fluid ejection controller of a fluid ejection device based on the second clock signal.
