Test Print with a Copied ZPL Command File

Test print with a copied ZPL command file for non-Windows operating systems.
  1. Create a text file with the following ASCII three characters:
    ~WC
    .
  2. Save the file as:
    TEST.ZPL
     (an arbitrary file name and extension name).
  3. Copy the file to the printer.
    For DOS, a file sent to a printer connected to the system’s parallel port would be as simple as: 
    COPY TEST.ZPL LPT1
    Other interface connection types and operating systems will have different command strings. See your operating system documentation for detailed instructions on how to copy to the appropriate printer interface for this test.
