    • An NFC connection is also available. The NFC contact point is located on the left bottom side of printer.

Checking Zebra Programming Language

Zebra printers use their own programming language (called ZPL or Zebra Programming Language) in order to help apps send commands to the printer for functions such as printing and formatting. Most Zebra printers are set to ZPL by default, but you may have one that is set otherwise which will cause ticket printing to fail.

  • Once the printer is connected to the Zebra Printer Setup app, select the Device Language option.

  • You should be able to see the Current Device Language that the printer is set to.

    • The language you want the printer assigned to is "XML and ZPL".

  • You can select "Set Device Language" to change it to the appropriate setting if it is not set to the expected "XML and ZPL" language.

    • Under the Command Language section, select "XML and ZPL" then select Apply to change the settings.
