Abstract: A fluid tank comprises a rigid container and a bag to receive a fluid. The bag is arranged within the container and comprises a fluid opening to allow a fluid to flow therethrough. A perimeter of the bag extends in a first direction and in a second direction and is supported within the container, such that the perimeter of the bag is movable in no more than the first direction and the second direction.

Abstract: Certain examples relate to mixing and/or supply cartridges for printing apparatus. One example implementation includes a reservoir to receive printing material from a printing apparatus and to return the received printing material to the printing apparatus. A storage medium stores a reservoir printing material level parameter indicative of the amount of printing material in the reservoir; a recirculation cycle counter indicative of the number of recirculation events experienced by the cartridge; a maximum recirculation cycle parameter indicative of the maximum number of recirculation events that may be experienced by the cartridge.
