Zebra Keyboard Display Unit (ZKDU) – Printer Accessory

The ZKDU is a small terminal unit that interfaces with the printer to enable ease of access to EPL or ZPL label forms stored in the printer.

The ZKDU is used for the following functions:

List label forms stored in the printer

Retrieve label forms stored in the printer

Input variable data

Printing labels

Switching between EPL and ZPL to support dual-format printer language format/form types. These forms can be stored and printed in late model Zebra label printers.

The ZKDU is strictly a terminal unit. It does not store data and cannot be used to change printer or printing parameters.
