Always a Perfect Fit

Zebra’s G-Series compact desktop printers for print widths up to

4 inches deliver best-in-class speed and performance. From the basic

GK™ model to the feature-rich GX™ model, the G-Series printers are

reliable, durable, and flexible to fit almost any low- to mid-volume

printing application and budget.

Fitting Choices

Built with Zebra durability and reliability, the G-Series GK model provides

the best value of all basic desktop thermal printers, while the premier

GX model supports a variety of industries and applications with the

widest range of features. Choose the space-saving direct thermal

version of either model for the smallest footprint of any 4-inch desktop

printer, or the direct thermal/thermal transfer version to save users time

with the easiest ribbon-loading system available.

With both EPL™ and ZPL®programming languages native on all models,

G-Series printers fit in perfectly with other Zebra printers. And a variety

of connectivity options makes them easy to integrate into existing local

or networked systems.

Zebra’s G-Series printers are a smart investment, and always a perfect fit.

Thermal Desktop Printers for Labels, Receipts and Tags

Zebra®G-Series™

Providing ease of use and durability,
the G-Series GK and GX models are
reliable desktop printing solutions
that are always a perfect fit.

You'll feel like they’re designed just
for you because they offer such a
broad array of options. And with
both EPL and ZPL pre-installed, you
can even switch between languages
depending on desired label format.

Basic GK Model: Your Best Value

The Zebra GK model is your best
value in a basic desktop thermal
printer. Its enhanced performance
delivers fast print speeds of up to 5
inches per second and fast first
label out. USB and serial
connectivity interfaces come
standard, or use the ZebraNet

®

10/100 Print Server option for
distributed printing.

Best-in-Class GX Model:
Feature-Rich

The Zebra GX model is best in
class with the widest range of
features in a desktop thermal
printer. It delivers even faster
first-label-out and, at 6 inches per
second, offers the fastest desktop
printer speed on the market. More
connectivity choices—
USB/serial/parallel, 10/100 Ethernet,
and wireless—ensure easy system
integration. An LCD panel, included
with wireless options, displays
prompts and
wireless status.

And with options that increase your
media flexibility, such as a movable
sensor, a peeler, and cutter for
labels or receipts—plus a version
with 300-dpi resolution—the GX
model fits a variety of applications
and environments.

Well-suited to retail, healthcare and
manufacturing industries, the extra
compact GK420d direct thermal printer
is the perfect fit wherever you need a
low-priced, space-saving printer for
receipts, coupons, labels or tags. Along
with fast print speeds of up to 5 inches
per second, it offers USB/serial connec­tivity and a 10/100 Ethernet option.
