Systems and methods for encoding data in a machine-readable image (e.g., an artificial fingerprint) are disclosed. The methods include segmenting a plurality of bits included in a bit stream to be encoded into a plurality of blocks such that each block includes two or more of the plurality of bits. The plurality of blocks are used to generate a minutiae template comprising a plurality of minutiae points each of which is representative of a local ridge discontinuity in a fingerprint, and is associated with a location and an orientation. An artificial fingerprint is generated from the minutiae template, and stored in association with the bit stream. The artificial fingerprint encodes the bit stream and comprises a plurality of ridges and a plurality of valleys.

A print configuration system will receive, from a first sensing modality, a first message indicating that a user has entered a first region where a print device is located. The system will access a profile for the user to identify a first configuration task, and it will cause the print device to perform the first configuration task. The system will later receive, from a second sensing modality that is different from the first sensing modality, a second message indicating that the user has entered a second region. The second region includes the print device and is a subset of the first region. In response to receiving the second message, the system will cause the print device to perform a second task that is different from the first configuration task.
