Zebra GK420d

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 connec-
tivity and a 10/100 Ethernet option.
