An ink cartridge (16) has a cartridge housing having a front side wall (90), a back side wall (91) opposite the front side wall, a pair of opposed left and right side walls (93,94) separating the front and the back side walls, and a bottom wall, the walls defining an internal cavity within the housing. The front and back side walls each have an internal surface that is curved and there is a generally uniform internal cartridge cavity thickness spacing existing between corresponding points on the respective internal surfaces at a respective section through the cartridge. An ink bag (70) is preferably located within the internal cavity and filled with liquid ink so that the ink bag makes contact with the front side wall, the back side wall and each of the pair of opposed left and right side walls and the bottom wall. <IMAGE>
