Guest We want to connect a bar code printer to a PLC S7 from Siemens in a packing line. The parts will arrive into a mold that it will check what part is through a series of sensors and then we want that the PLC to tell the printer to print a specific label for that specific part. Basically our questions is how can we interface the PLC with your printer.


Depending on the communication ports available on the PLC we can normally communicate with a printer sending a simple text file formatted in the printer’s native language. The Datamax H-4212 has the full range of interfaces including RS-232, Parallel, USB, and Ethernet and can be set-up to work with your PLC directly. This unit also has an optional GPIO interface for further integration with sensors and other types of triggers.
