Section 1: RW Series Introduction
Description
The Zebra RW Mobile Printer series are low-cost, portable, direct thermal printers.
They can be carried by the operator using a shoulder strap or belt clip, sit at a
work space, or be mounted in a vehicle using an optonal Docking Cradle. Each
model is powered by a Li-ion battery pack which makes it particularly useful in
environments where AC power is not readily available. The RW series of mobile
printers deliver traditional Zebra reliability in a transportable printer for the mobile
work environment.
Operating Modes
• Internal Media Mode: Media is supplied from a roll mounted in the printer’s
media compartment..
• External Media Mode (RW 420 only): Media is supplied from an external source,
typically a bin containing fan-fold media, or a larger roll of media that exceeds the
capacity of the RW 420’s media compartment. Media is fed through a slot in the
bottom of the printer’s lower housing. The printer’s congurator must have the
external media option selected to make use of this feature. (Refer to pg. 3-3 for
more information on the RW 420 congurator.)
Printing Technology
The RW series printers utilize direct thermal printing wherein a substrate, typically
paper, is coated with a chemical that changes to a dark color upon exposure to
heat over a period of time to form an image.
Communications
Communications between the RW series printers and a host terminal can occur in
three basic ways:
• By a cable between the printer and its host terminal using either RS-232C serial
or USB protocols.
• By means of a Bluetooth
®
short range radio frequency link.
• By means of a wireless LAN (Local Area Network) per 802.11 specications.
Certain RW models can be congured with both a Bluetooth and an 802.11b/g
radio.
