A system is provided which incorporates apparatus for sensing and generating as linear rod positions the amount registered on the indicia wheels of dispensing pumps, a date receiving and storing device adapted to be inserted into the pump for receiving and storing the data from the data generating device as linear positions of slide means, and a data recording device adapted to receive the data receiving and storing device and record the data retained by the receiving and storing device. The linearly positionable rods are coactable with stop means on the surface of the indicia wheels to provide a linear position corresponding to the data on the indicia wheels; the data receiving and storing device includes detented slide means adapted to sense the position of the linearly positionable rods on the generating device and retain said positions are corresponding positions of the slide means; the data recording device includes means to sense the position of the slide means on the data receiving and storing device and print characters corresponding to the position thereof. Preferably the data recording device is adapted to function either independently of or mounted on the pump and in conjunction with the operation of the data generating device.
