Claim:
A priming fluid cartridge comprising: 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 that faces upward when the printing fluid cartridge is in use, such that the electrical interface is exposed to an exterior of the printing fluid cartridge; a recess that is opened upward when the printing fluid cartridge is in use, wherein the recess is positioned farther from the rear face than the electrical interface is with respect to the first direction, and the recess and the electrical interface intersect a plane which is parallel with the first direction, the second direction, and a third direction that is perpendicular to the first direction and the second direction; a chamber configured to store printing fluid therein; and a printing fluid supply portion positioned at a lower portion of the front face when the printing fluid cartridge is in use, and comprising a printing fluid supply opening, wherein 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; wherein the electrical interface is positioned above the recess when the printing fluid cartridge is in use and is offset from the printing fluid supply portion with respect to the third direction; wherein the printing fluid supply opening is positioned below the electrical interface when the printing fluid cartridge is in use; and wherein the electrical interface is positioned closer to the rear face than the printing fluid supply opening is.
