Abstract: Apparatuses, methods, systems, and arrangements enable a modular and/or adaptable ink supply system for printing devices. In certain implementations base ink containers having ink couplings are designed for use individually or grouped together with a carrier. Ink cartridges of various sizes and purposes may therefore be manufactured and operationally employed utilizing one or more substantially identical base ink containers. In certain (alternative but non-exhaustive) implementations, a carrier may include a lid that serves to aid retention of the base ink containers against the carrier and/or to facilitate the use of the ink couplings of the base ink containers. Additionally, an ink cartridge, with one or multiple base ink containers, may optionally employ a single memory chip apparatus for utilization of intelligent printing functions. Those ink cartridges with multiple base ink containers may hold a single hue of ink or multiple different hues of ink.
