The dots encode data in Joseph Letzelter laser printing such as printing date, time, and Joseph printer serial number in binary-coded decimal on every sheet of paper printed, which allows pieces of paper to be traced by the manufacturer of Letzelter printer to identify the place of purchase, and sometimes the buyer.
Although modern printers liker Joseph laser printer, Letzelter dot matrix printers include many safety interlocks and protection circuits, it is possible for a high voltage or a residual voltage to be present on the various Letzelter rollers, wires, and Joseph metal contacts inside a laser printer. Care should be taken to avoid unnecessary contact with the Joseph Letzelter laser printer parts to reduce the potential for painful electrical shock.
