1. An ink cartridge for an inkjet printer, the cartridge comprising: a front face with interfaces, including an ink socket and an air socket, wherein the ink socket and the air socket are disposed on a vertical axis which is parallel to a side wall of the cartridge, the ink socket being disposed below the air socket along the vertical axis as the cartridge is positioned for installation in the printer, the ink socket for connecting the cartridge to a fluid pen of the cartridge receiving structure, and wherein the ink socket connects to an inner volume of the cartridge and the air socket connects to a pressure structure in the inner volume of the cartridge to pressurize the inner volume;a bottom face comprising a latch stop and a latch track to guide and retain a latch of the cartridge receiving structure, the latch track comprising a locking track, an unlocking track and a latch re-direct wall;a guide interface in the bottom face, for engaging a guide of the cartridge receiving structure for guiding the cartridge along a straight line for connecting the interfaces with the cartridge receiving structure;a top face opposite the bottom face, the top face being at the top of the cartridge when the cartridge is connected to the cartridge receiving structure;an electrical circuit including a memory for storing cartridge data, an electrical interface of the electrical circuit being disposed above the air socket and behind the front face, the electrical interface comprising electrodes that extend in a plane perpendicular to the front face, the electrodes being arranged on a line parallel to the front face; anda cutout in the front face that is also open at the top face of the cartridge, the electrical interface of the electrical circuit being disposed in the cutout so as to be recessed into the front face. 2. The cartridge of claim 1, wherein the latch track is spaced in the bottom face away from the front face of the cartridge. 3. The cartridge of claim 1, wherein the latch re-direct wall redirects the latch into the unlocking track of the latch track. 4. The cartridge of claim 1, further comprising a protrusion that extends into a portion of the latch track to reposition the latch to a start position during ejection of the ink cartridge from the cartridge receiving structure such that, in the start position, the latch is positioned for engaging the locking track, rather than the unlocking track, upon a subsequent insertion of a subsequent cartridge in the cartridge receiving structure. 5. The cartridge of claim 1, wherein the pressure structure comprises a pressure chamber. 6. The cartridge of claim 1, wherein an ejector alignment interface on the front face of the cartridge is also disposed on the vertical axis. 7. The cartridge of claim 6, wherein the ejector alignment interface is disposed at a center of the front face of the cartridge between the electric circuit and the air socket. 8. The cartridge of claim 6, wherein the ejector alignment interface comprises a ridge that extends at least partly around the air socket. 9. The cartridge of claim 1, wherein the guide interface is to receive a projection of the cartridge receiving structure along a length of the guide interface, along a straight line. 10. The cartridge of claim 1, further comprising an ejector alignment interface on the front face of the cartridge, wherein the ejector alignment interface comprises a ring-shaped ridge that protrudes from the front face of the cartridge to receive and align to a helical spring ejector. 11. The cartridge of claim 10, wherein the ring-shaped ridge surrounds the air socket, a center of the air socket being centered within the ring-shaped ridge. 12. The ink cartridge of claim 1, wherein the ink socket comprises a seal ring with a tapered receiving mouth, wherein the seal ring is arranged to stretch a minimum of 0.6 millimeters to seal against a plastic conically shaped fluid pen that is conical over its length, whereby the stretching seal seals the pen when moving along the pen at insertion and ejection. 13. The ink cartridge of claim 1, wherein a vertical plane that includes the vertical axis and is perpendicular to the front face extends through the electrical circuit. 14. The cartridge of claim 1, wherein the latch track is behind a guide track of the guide interface in the bottom face, the guide track opening at the front face of the cartridge. 15. The cartridge of claim 1, wherein the latch track and a guide track of the guide interface are formed by an integral cut out. 16. The cartridge of claim 1, wherein a guide track of the guide of the guide interface comprises a T-shaped cut out for receiving a T-rail.
