A data collection system for, and methods of, providing reliable store-and-forward data handling by encoded information reading terminals can utilize ad-hoc peer-to-peer connections in order to store data that is normally stored on a single terminal only, in a redundant manner on two or more terminals. The subject printheads are characterized by having a multiple printhead die printhead and a multiple reservoir housing affixed to the multiple die printhead. The melt heat exchanger is adapted to reduce heat loss at the exposed upper surface portion. A noise shaping modulator can be employed for modulating a fractional part associated with the repetition number.
