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 | • Media handling |
• Hardware | • Power |
• Firmware | • Ribbon handling |
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.
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.
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.

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.
