a housing assembly having top and bottom housing members that defines a region between the top and bottom housing members for storing a stack of print media sheets;
an ink storage assembly mounted on an underside of the bottom housing member, the ink storage assembly and the underside of the bottom housing member defining at least one ink chamber therebetween, each ink chamber including a deformable film for receiving ink between the deformable film and the underside of the bottom housing member; and
ink connection nozzles in fluid communication with each respective ink chamber,
wherein a portion of the bottom housing member extends beyond a peripheral edge of the top housing member to define an ink supply connection manifold with the ink storage assembly, the ink connection nozzles being located on the ink supply connection manifold.
2. A print media cartridge as claimed in claim 1 , further comprising a sheet transport mechanism mounted in the housing assembly to feed the sheets from the housing assembly.
3. A print media cartridge as claimed in claim 1 , in which each ink connection nozzle includes at least one piercable ink seal which seals the at least one ink chamber.
4. A print media cartridge as claimed in claim 3 , in which the ink storage assembly includes at least one air inlet in communication with the at least one ink chamber on a side of the deformable partition opposite the side on which the ink is contained.
