Signal transmission and signal processing device for printers, esp. inkjet and dot-matrix printers, has transponder with HF antenna arranged on the modules of the printer to be replaced or moved

摘要

To avoid mistakes during exchange or replacement of modules, which occur if contact is made at this point, the printer HF antennae are arranged with spacing to the transponder HF antenna, such that the printer HF antenna is connected to the printer control via at least one data- and/or clock-line for bi-directional data transmission, and thereby a completely contact-less communication is realized between the module to be replaced or exchanged and the printer control.
