RW 420 Battery Eliminator
If you keep and use your printer in the cab—fixed-
mounted and powered by your vehicle’s power
system instead of the printer’s battery—look to the
RW 420 Battery Eliminator to reduce your cost of
owning the RW 420 printer.
Lithium-Ion Batteries
Lithium-ion (Li-Ion) cells represent the latest in mobile
battery technology. They offer higher power-to-volume
and power-to-weight than their nickel metal hydride
and nickel cadmium counterparts. Order spare Li-Ion
batteries for your RW series printer to guarantee you’ll
always be charged up and ready to go!
ZebraCare™ Depot Service Agreements
A ZebraCare Depot service agreement is a cost-
effective means of planning and budgeting your
annual maintenance expenditures. This back-to-factory
service ensures that trained and certified Zebra
technicians will bring your printer back to factory
specifications every time. Zebra offers four plans to
meet your specific needs.

your application and budget. We can also pre-print
your company logo, instructions, terms and conditions
and other information, allowing you to maximize the
functionality of your receipts and documents.
Considerations When Selecting the Best Material
for Your Mobile Application
Heat
Since direct thermal materials are heat sensitive,
exposure to extreme heat will cause the chemicals in
the material to react, turning the document black and
unreadable. To avoid this problem, choose our heat-
resistant 8000D High Temp 3.2 mil Receipt material,
which withstands temperatures up to 194º F (90º C).
Moisture
Most paper materials on the market have limited
durability against moisture and degrade once
subjected to it. Zebra’s PolyPro™ 4000D 3.8 mil
Receipt synthetic material offers a waterproof and
tear-proof solution.
Thickness
Thicker materials tend to be more durable and are
perceived as higher quality. However, the thicker the
material, the less paper per roll, resulting in fewer
documents that can be printed before the roll needs
to be changed.
Archivability
To reach published archival duration specifications,
documents need to be stored with compatible
materials in a dark place with relative humidity
between 45 and 65 percent, and temperatures below
77º F (25º C).
Topcoating
One of the biggest differences between thermal papers
is their coatings, which are unseen by the naked eye.
All thermal papers have a basecoat and a thermal coat,
but not all of them have a topcoat. A topcoat provides
an extra layer of protection for the image.
