DESC: The Datamax I-4210 brings integrated application computing power to the I-Class family of industrial barcode label printers with the addition of the MCL Client from MCL Technologies. MCL, or Macro Command Language, is a completely integrated application development suite tuned for the demands of data collection applications. After developing an application on an MCL development computer the application project is uploaded to the I-4210 where it is hosted as a self-sufficient application. The development computer is no longer necessary for the application to run and the MCL-enabled I-4210 can interact with printer-resident look-up tables as well as wired and wirelessly connected remote ERP systems or other host databases.
