A printing fluid cartridge includes a front face oriented toward a first direction, a rear face positioned opposite the front face and oriented toward a second direction opposite the first direction, an electrical interface disposed at a particular face, such that the electrical interface is exposed to an exterior of the printing fluid cartridge, a chamber configured to store printing fluid therein, and a printing fluid supply portion positioned at the front face, and comprising a printing fluid supply opening. The printing fluid supply portion is configured to supply the printing fluid from an interior of the chamber to an exterior of the chamber via the printing fluid supply opening. The printing fluid supply opening is positioned below the electrical interface when the printing fluid cartridge is in use. The electrical interface is positioned closer to the rear face than the printing fluid supply opening is.
