The present invention relates to an inkjet printer for printing on goods, wherein said printer comprises a computer (20) for controlling the operation process, at least one replaceable tank (24) in the shape of a bottle filled with a previously known quantity of a liquid (30), an intermediate container (32) arranged in the printer and filled with the liquid (30) from the tank (24) as well as a device also arranged in the printer for detecting the quantity of liquid (30) drawn from the tank (24).
