1. An ink cartridge for an inkjet printer, comprising: a bottom face and a front face;interfaces on the front face for connection to a cartridge receiving structure, the interfaces including an ink interface;a guide interface in the bottom face for guiding the cartridge along a straight line for connecting the interfaces; anda latch stop and a latch track, disposed in the bottom face, to guide and retain a latch of the cartridge receiving structure. 2. The ink cartridge of claim 1, wherein the latch track comprises a locking track and an at least partly separate unlocking track, and is arranged to accommodate movement of the latch with respect to the latch stop, said movement being: along the locking track into a locked engagement position at insertion, andalong the unlocking track into an unlocked position at ejection. 3. The ink cartridge of claim 2, wherein the latch stop is disposed between the locking track and the unlocking track. 4. The ink cartridge of claim 2, further comprising a projection extending into the latch track that directs the latch to the locking track, rather than the unlocking track. 5. The ink cartridge of claim 2, comprising a latch guide wall at an end of the locking track to direct the latch to the latch stop. 6. The ink cartridge of claim 1, further comprising a jog in the latch track directing the latch along a first side of a latch stop for insertion of the ink cartridge in the cartridge receiving structure, wherein the latch moves along a second, opposite side of the latch stop during removal of the ink cartridge. 7. The ink cartridge of claim 1, wherein the latch stop comprises a latch stop wall and a latch abutment, the latch abutment comprising a protrusion in the latch stop wall for retaining the latch from sliding off the latch stop wall. 8. The ink cartridge of claim 1, wherein the guide interface comprises a guide track that extends parallel to said straight line. 9. The ink cartridge of claim 8, wherein the guide track and the latch track are formed by one integral cut out in the bottom face of the ink cartridge. 10. The ink cartridge of claim 8, wherein the guide track comprises a T-shaped cut out for guiding a corresponding T-rail guide of the cartridge receiving structure. 11. The ink cartridge of claim 10, wherein the guide track comprises a guide stop for engaging an end of the T-rail guide of the cartridge receiving structure. 12. The ink cartridge of claim 8, wherein the guide track comprises a tapered receiving opening at the front face of the ink cartridge. 13. The ink cartridge of claim 12, wherein the guide track comprises flanges being tapered at the receiving opening. 14. The ink cartridge of claim 8, wherein the ink interface comprises a socket for receiving a pen that has a length that is the same as, or shorter than, the guide track, wherein a central axis of the socket is parallel to said straight line. 15. The ink cartridge of claim 1, wherein the ink interface comprises a socket for receiving a conically shaped pen of the receiving structure, the ink interface comprising a seal ring of resilient material configured to stretch an inner diameter of the seal ring for engaging the pen along its conical shape at insertion. 16. The ink cartridge of claim 1, wherein the interfaces comprise an electrical circuit for electrical contact between the ink cartridge and the cartridge receiving structure. 17. The ink cartridge of claim 16, wherein the electrical circuit is sunken in the front face of the ink cartridge so that electrical contact is made after at least one other interface is already connected. 18. The ink cartridge of claim 16, wherein the electrical circuit comprises electrodes that extend in a plane that is approximately perpendicular to the front face of the ink cartridge, and approximately parallel to the straight line, for establishing a sideways connection with a corresponding connector circuit of the cartridge receiving structure. 19. The ink cartridge of claim 16, wherein: the electrical circuit is disposed in an upper portion of the front face of the ink cartridge; andthe ink interface is disposed in a lower portion of the front face of the ink cartridge. 20. The ink cartridge of claim 1, wherein the interfaces on the front face comprise an ejector alignment interface, the ejector alignment interface comprising a ring-shaped ridge.
