Migration guide  
Zebra® G-Series™ printers  
To facilitate easy migration from your current 28 Series desktop printers to the new G-Series desktop printers,  
this document outlines the key operational differences and considerations:

Communication  
1. The G-Series printer’s serial port is of a cross-over  
null-modem configuration, which is the same pin-out  
arrangement as on the ZPL-based 28-series printers.  
For serial port users of EPL-based 28-series printers,  
an appropriate serial cable or adaptor can be  
sourced. The part numbers are G105950-054  
and 105850-026 respectively.  
3. Users of the external 10Base-T print server device on  
their 28-series printers are recommended to migrate to  
a G-Series printer with internal 10/100 Ethernet option.  
4. To aid the setup of the G-Series printers, representative  
icons appear above the printer’s interface ports and  
power supply.  
2. The GX420 and GX430 printers’ parallel port is of a  
DB-25 configuration. A switchbox-style parallel cable  
can be used. The part number is 105850-025.

Hardware  
1. Unlike the 28-series thermal-transfer printers,  
the thermal-transfer G-Series printers do not have  
a lid-release catch.  
2. The operation of the dispenser option’s peel sensor  
is controlled via command code (as opposed to via  
a switch on the 28-series printers). Legacy users  
can control the sensor via the appropriate EPL OP  
command or ZPL ^MMP command. Newer users  
might wish to adopt a SGD “media.printmode”  
method of control.  
3. The GX420 and GX430 printers have a moveable sensor  
option available to them. This full-width reflective  
sensor can be moved across the whole width for use  
in detecting black-mark registration marks. The multi-  
position transmissive sensor caters for centralised  
registration gaps, notches or die-cut holes and for the  
28-series printers’ right offset position.  
4. The peaked area on the lower media pathway  
corresponds to an upper array of sensors. The direct-  
thermal printers have a three-peak design, whereas the  
thermal-transfer printers have a four-peak design. The  
range of transmissive-sensor movement is the same on  
both the direct-thermal and thermal-transfer printers.

Media handling  
1. The default media action of the G-Series printers  
resembles that of an EPL-based 28-series printer: the  
printer will not feed automatically at power-on, only  
following a lid closure. If you are changing between  
two different styles of media, you should carry out  
a manual calibration. This can be achieved via the  
printer’s two-flash Feed-button sequence. The printer  
can be changed to feed at both power-on or lid closure  
using the ZPL ^MF command.  
down method). Rotate the thumb wheel inwards on  
the direct-thermal printers to keep the guides apart. For  
thermal-transfer printer guides, rotate the thumb wheel  
outwards to keep them apart.  
4. For GX420 or GX430 printers equipped with a cutter  
option, its default operation is to double-cycle following  
every 25th cut. This automatic dual-cut is intended  
as a cleaning action to maintain the life of the cutter.  
This action can be disabled via the appropriate  
SGD command “cutter.clean_cutter”, but it is  
not recommended.  
2. The G-Series printers are easier to load than 28-series  
printers because they do not have separate roll holders  
and guides. They are one integrated element and  
support 12mm/0.5" cores.  
5. Providing the relevant option is installed, common  
media handling can be controlled via the SGD  
constructs. The “media.printmode” command can be  
used to manage G-Series printers in tear, peel or cutter  
modes of operation.  
3. If using fan-fold media or an external media roll, the  
centralised thumb wheel can be used to keep roll  
holders open (as opposed to using the older screw-  
Power  
1. The power supplies for the thermal-transfer G-Series  
printers (the GK420t, GX420t and GX430t) are located  
in the upper packaging. This is the same as 28-series  
printers. However, direct-thermal G-Series printers  
(the GK420d™ and GX420d™) have their power  
supplies located in the lower packaging beneath  
the printer itself.  
3. When looking at the rear of the G-Series printers,  
the location of the power on/off switch is on the right.  
This is different from that of the 28-series.  
2. The G-Series printers’ power supplies are of a 24-volt  
DC design, as opposed to the 28-series printers’ 20-volt  
DC design. Additionally, the power cable’s attachment  
to the supply itself – the line socket – is of a C13 “kettle”  
style, which is different from the C5 “clover-leaf” style  
of the 28-series. Power supplies and power cables are  
specific to printer models. G-Series printers cannot use  
28-series printers’ power supplies and vice versa.

Ribbon handling  
1. The G-Series ribbon-sensing mechanism requires the  
ribbon to have a reflective trailer. As such, the uni-  
ribbon format should be used for GK420t™, GX420t™  
and GX430t™ printers whenever they are being used in  
the thermal-transfer mode of operation.  
2. The inverted ribbon mechanism of the G-Series printers  
is different from that of the thermal-transfer 28-series,  
but it enables a far easier and quicker process. Refer to  
the ribbon-loading instructions in the relevant printer’s  
user guide for full instructions.
