Abstract: A printable liquid supply cartridge includes a printable liquid reservoir extending between a first side and a second side, and between a front end and a rear end. The front end includes a printable liquid outlet to receive a first fluid pen and a gas inlet, above the printable liquid outlet, to receive a second fluid pen. The front end also includes an interface support at the first side, the support having an I2C data interface that includes electrical connection pads exposed on an interior side of the support to face from the first side towards the second side, the electrical connection pads being arranged vertically and to make contact with the printer data interface at least partially inserted into the second portion.

Abstract: A printable liquid supply cartridge comprises a housing enclosing an internal volume. The housing has a front end to connect to a printer and first and second sides extending from the front end to a rear end. The front end has a printable liquid outlet closer to the bottom than to the top and has a gas inlet above the printable liquid outlet, each of the printable liquid outlet and the gas inlet to facilitate insertion of a respective fluid pen therein. There is a recess in the front end above the gas inlet, the recess being delimited by a first wall having an internal side and an external side that is part of the first side. An I2C data interface comprising at least three electrical connection pads are exposed on the internal side of the first wall facing towards the recess, the connection pads arranged in a top to bottom direction.
