The KDU Plus™ is a terminal device with memory for storing files and maintaining one or 
more remote printers. The KDU Plus has a larger laptop style keyboard than the Zebra’s 
original KDU design.

The KDU Plus is designed for the following functions:

•

List label forms stored in printer

•

Retrieve label forms stored in printer

•

Input variable data

•

Printing labels

•

File storage and transfer

The KDU Plus is designed to work with ZPL and EPL printers by dynamically detecting and 
switching the printer’s communications configuration (DTE or DCE) to match your Zebra 
printer. By default, the KDU Plus will start up forms mode. This is compatible with the 
operation of Zebra’s original KDU. The KDU Plus is configurable to work in ZPL or terminal 
modes too.

The KDU Plus has file transfer and storage capabilities. This is great for maintaining remote 
and stand alone printers with label forms, logos and smaller font sets. 

The KDU Plus has two configurable serial port and a PS/2 port to connect to other data input 
devices such as scanners, weigh scales, etc..

The +5 volts from the printer’s serial (pin 9) provides power for the KDU Plus and any 
additional input devices attached to the KDU Plus. 

Maximum total current draw for the GC420 printer’s serial (and parallel) port: 750mA 
The KDU Plus’s current without external input devices attached is: 50mA

Caution • The KDU Plus’s input ports (AUX1, AUX2, and PS/2 style) are not fused.

the printer.
