The ink delivery device comprises a pressure controller operating on the ink conduit between the print head and the ink supply, the pressure controller including a sealing device adapted to seal off the ink conduit and a cap adapted to selectably expose the pressure controller to ambient conditions. The pressure controller is adapted to purge the print head of ink between print jobs.
