Abstract
An ink jet printer has an ink filling device for an ink jet print head wherein the ink jet print head can be filled with the filling device. The ink filling device has an ink reservoir and a discharge opening. The print head has an ink chamber with a feed opening for ink and can be filled when it is installed in an ink jet printer. The discharge opening is arranged in a hollow body with a variable-volume that moves ink from the ink reservoir when the volume is increased and that discharges ink via the discharge opening when the volume is decreased.
