Abstract A closed supply container that is filled with air and ink is associated with a print head in a one-to-one association. During a printing process, ink is drawn from the supply container into the print head via a connecting line, such that a negative pressure in the supply container is increased. A sensor in the supply container measures the negative pressure and transmits a measurement value to a controller that switches a valve associated with the supply container so that ink is conveyed from an ink storage container into the supply container of the measurement value falls below a predetermined first lower limit value of the pressure such that the fluid pressure in the supply container increases.
