Abstract: Ink-jet printer and method for supplying ink-jet printer with printing fluid. Device includes first reservoir configured to contain first volume of printing fluid at first level relative to reference plane, supply system structured to force printing fluid towards first reservoir, and second reservoir configured to contain second volume of printing fluid at second level relative to reference plane. Second level is lower than first level by level difference value. A conduit is configured to receive printing fluid from first reservoir and convey printing fluid towards second reservoir, and ejector units are arranged to receive printing fluid from conduit. An ejection plane in which ejector units lie is located at a height relative to reference plane higher than average of first and second levels to generate a back pressure in ejector units. Flowrate of printing fluid inside conduit is greater than a maximum flowrate of printing fluid ejectable from ejector units.
