The details below are a guide to installing and configuring a Zebra GK420D printer for use with ByBox Despatcher.

Despatcher is a web-based application for printing ByBox shipping labels for distribution through the network. You need to install and configure  a Zebra GK420D printer to use Despatcher,

 Because both the web page and the print agent are independently linked to ByBox web-servers, the print agent, does not necessarily need to be installed on the same machine that is using the web page to connect to the labels.

Before you begin

Make sure you have the following from ByBox:

    • Zebra ZD420 Direct Thermal Label printer – complete with USB lead and roll of labels.
    • Customer specific website login.

Make sure you have set up the following: 

    • An internet enabled Windows PC with Google Chrome installed and 1 spare USB socket. 
      Note: You must use Chrome to set up this printer. If you do not have Chrome, contact ByBox Customer support for assistance.
    • 1 spare standard plug socket.
    • Either administrator access rights on the PC or someone available on site at the time of installation with the appropriate access to install the required printer drivers.
