A printing cartridge includes a cover that defines a cylindrical storage volume and a print media feed slot. A cylindrical hollow core extends along a central axis of the cover. At least one ink container is positioned in the core. A length of print media is rolled about the core and positioned to be fed from the slot. A feed mechanism is positioned in the cover and is engageable by a drive mechanism of a printer from a position outside the cover and operable on the print media to feed the print media from the slot.
