Abstract
An ink cartridge includes a flexible bag filled with a liquid ink, and a cartridge housing that holds the bag. The bag is filled to a predetermined percentage of its full volume to fill the bag to less than its capacity in order to prevent the bag from rupturing, but is filled sufficiently to substantially occupy the housing when folded. Preferably, the bag has a width that is greater than a width of the housing and has a length that is less than a length of the housing so that the bag need only be folded widthwise to fit in the housing.
