The G-Series printer’s serial port is of a cross-over

1.

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.

The GX420 and GX430 printers’ parallel port is of a

2.

DB-25 configuration. A switchbox-style parallel cable
can be used. The part number is 105850-025.

Users of the external 10Base-T print server device on

3.

their 28-series printers are recommended to migrate to
a G-Series printer with internal 10/100 Ethernet option.

Unlike the 28-series thermal-transfer printers,

1.

the thermal-transfer G-Series printers do not have
a lid-release catch.

The operation of the dispenser option’s peel sensor

2.

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.

The GX420 and GX430 printers have a moveable sensor

3.

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.

The peaked area on the lower media pathway

4.

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.
