    Abstract: A printing apparatus, a printing system and a method are disclosed. The method of moving printing fluid within a printing apparatus includes selectively providing a first pressure difference between a first reservoir and a second reservoir by a differential pressure system to cause the printing fluid to move from the first reservoir through a printing fluid applicator to the second reservoir. The method also includes selectively providing a second pressure difference between the first reservoir and the second reservoir by the different pressure system to cause the printing fluid to move from the second reservoir through the printing fluid applicator to the first reservoir.

    Abstract: An example of a printing fluid supply connector is described that has a first connector and a second connector, where each of the first and second connectors is to fluidly connect to a respective replaceable reservoir of printing fluid. The printing fluid supply connector also has an outlet to fluidly connect to a printer and a selector to selectively fluidly connect one of the first and second connectors to the outlet in response to an electrical control signal or to fluid pressure at the first and second connectors.

    Abstract: In an example, a selection valve of a fluid supply system is disclosed. The selection valve selectively couples a source of pressurized air to one of first and second fluid supply cartridges, in the fluid supply system, to provide fluid to a printhead, the one of first and second fluid supply cartridges being coupled to the source of pressurized air at a time and other fluid supply cartridge being vented to the atmosphere. The selection valve includes a sleeve to provide interconnections with the source of pressurized air, the first and second fluid supply cartridges, and the atmosphere. Further, the selection valve includes a core disposed rotatably inside the sleeve to selectively couple the one of first and second fluid supply cartridges to the source of pressurized air and the other fluid supply cartridge to the atmosphere for switching the pressurized air between the first and second fluid supply cartridges.
