QL 420 User’s Guide 7
Introduction
Thank you for choosing our Zebra QL 420 Mobile Printer. This
rugged printer is sure to become a productive and efficient addi-
tion to your workplace thanks to its innovative design. Because
it’s made by Zebra Technologies Corporation, you’re assured of
world-class support for all of your bar code printers, software,
and supplies.
• This user’s guide gives you all the information you’ll need
to operate the QL 420 printer.
• The QL 420 uses the CPL programming language. To cre-
ate and print labels using the CPL language, refer to the
Mobile Printer Programming Guide (available on our web-
site at:
http://www.zebra.com/SS/manuals.htm) and our
Label Vista™ label creation program.
• The QL 420 has an optional interpreter for the ZPL II
®
Pro-
gramming Language which interprets commands up to X.8
firmware. The printer must be equipped with the optional
memory upgrade and appropriate application in order to
use this function. A ZPL II Program Guide (part #46530L)
can be used as reference for the ZPL II label design pro-
gramming language. If either manual was not ordered
with the printer, simply call your re-seller or Zebra Technol-
ogies Corporation or visit the Zebra web site.
Unpacking and Inspection
Inspect the printer for possible shipping damage:
• Check all exterior surfaces for damage.
• Open the media cover (refer to “Loading the Media” in the
Getting Ready to Print section) and inspect the media
compartment for damage.
In case shipping is required, save the carton and all packing
material.
Reporting Damage
If you discover shipping damage:
• Immediately notify and file a damage report with the ship-
ping company. Zebra Technologies Corporation is not re-
sponsible for any damage incurred during shipment of the
printer and will not cover the repair of this damage under
its warranty policy.
• Keep the carton and all packing material for inspection.
• Notify your authorized Zebra re-seller.
