Abstract | A printing device comprises a printing fluid supply; a plurality of printheads connected in parallel to the supply by a first flow path and a second flow path; a first fluid pressure source to create a negative fluid pressure between the supply and the first openings; a second fluid pressure source to create a positive fluid pressure between the supply and the second openings; and a controller. Each printhead comprises a closable first opening connected to the first flow path and a closable second opening connected to the second flow path, and has an associated mechanism to increase a fluid pressure in the printhead. Each first opening is to open in response to operation of the associated mechanism. The controller is to identify a first printhead for which printing fluid in the first printhead is to be recirculated; and operate the mechanism associated with the identified printhead. |
