Micro-fluid ejection apparatuses and devices, and methods related to communication in and with the same. One such micro-fluid ejection apparatus includes a controller configured to generate a data signal, and a transmitter configured to convert the data signal to a current signal. The apparatus further includes a conductor capable of carrying the current signal, and a receiver configured to receive the current signal from the conductor and to convert the current signal to a second data signal. The micro-fluid ejection apparatus is configured to operate on the second data signal. In one embodiment, the micro-fluid ejection apparatus may be a printing apparatus, such as an inkjet printing apparatus. In some embodiments, the current signal comprises a pair of corresponding differential current signals and/or current transfer logic signals offset from a base amperage level. In some embodiments, the transmitter and controller are provided within a main printing control board, while the receiver is provided within a printhead cartridge or a printhead carrier, and the operation comprises a printing function.
