Battery
Printer Overview
The printer uses a two-cell Li-Ion battery pack with a charge time of under 3.5 hours using a 7.5W USB
charger while printer power is on. The battery allows the printer to print reliably without recharge for three
work days under the following conditions: 25 stops per day and will power up the device 25 times per day;
up to 500 3x8.5 in. receipts per 8-hour shift with 13% coverage.
Operating Temperature Charging Temperature Storage Temperature
-10°C to 50°C
(14°F to 122°F)
NOTE: Note the following:
- Power down the printer before removing the battery to minimize the risk of corruption.
- The printer will only function properly with genuine Zebra battery packs.

Printing Technology
The printer uses the Direct Thermal method to print human readable text, graphics and barcodes. It
incorporates a sophisticated print engine for optimal printing under all operational conditions. Direct
thermal printing uses heat to cause a chemical reaction on specially treated media. This reaction creates a
dark mark wherever a heated element on the printhead comes in contact with the media. Because the
printing elements are arranged very densely at 203 dpi (dots per inch) horizontal and 200 dpi vertical,
highly legible characters and graphic elements may be created a row at a time as the media is advanced
past the printhead. This technology has the advantage of simplicity, as there is no requirement for
consumable supplies such as ink or toner. However, since the media is sensitive to heat, it will gradually
lose legibility over long periods of time, especially if exposed to environments with relatively high
temperatures or in direct sunlight.

USB Communications
LAN
CAUTION: The printer should be turned off before connecting or disconnecting a communication cable.
The standard cable connection for the printers is a USB 2.0 communication and charging cable. One end
of the cable has a USB Type-A connector while the other end is USB Type-C
The small Type C connector on the USB cable plugs into the printer. The connector is not keyed and
therefore can be plugged in in either direction. However, do not try to force the cable if it does not plug in.
The Type A end of the cable must be plugged into any USB 2.0 host port. The printers utilize the USB
cable to charge the printer (see AC-to-USB Charger on page 15) and for communications between the
printer and computer.

Using the Printer
Wireless Communications with Bluetooth
Bluetooth is a worldwide standard for the exchange of data between two devices via radio frequencies.
This form of point-to-point communication does not require access points or other infrastructure. Bluetooth
radios are relatively low powered to help prevent interference with other devices running at similar radio
frequencies. This limits the range of a Bluetooth device to about 10 meters (32 feet). The default for the
printers is Class 2. Both the printer and the device it communicates with must follow the Bluetooth
standard.
Bluetooth Networking Overview
Each Bluetooth enabled printer is identified by a unique Bluetooth Device Address (BDADDR). This
address resembles a MAC address whereby the first three bytes are vendor, and the last three bytes are
device (e.g. 00:22:58:3C:B8:CB). This address is labeled on the back of the printer via a barcode for ease
of pairing (Figure 5 on page 28). In order to exchange data, two Bluetooth enabled devices must establish
a connection. Bluetooth software is always running in the background, ready to respond to connection
requests. One device (known as the client) must request/initiate a connection with another. The second
device (the server) then accepts or rejects the connection. A Bluetooth enabled printer will normally act as
a peripheral creating a miniature network with the terminal sometimes referred to as a “piconet”. Discovery
identifies Bluetooth devices that are available for pairing whereby the central device broadcasts a
discovery request and devices respond. If a device is not discoverable, the central cannot pair unless in
knows the BDADDR or has previously paired with the device. If both devices support Bluetooth 2.1 or
higher they will use Security Level 4 Secure Simple Pairing (SSP), a mandatory security architecture that
features two (2) association models: Passkey Entry (default 0000) and Just Works (no user confirmation).
26
Bluetooth Security Modes
Security Mode 1 Security Mode 2 Security Mode 3

Simple Secure Pairing: a new security architecture introduced supported in BT >= 2.1. Service-level
enforced, similar to mode 2. Mandatory when both devices are BT >= 2.1. There are four association
models currently supported by mode 4. Security requirements for services must be classified as one of
the following: authenticated link key required, unauthenticated link key required, or no security required.
SSP improves security through the addition of ECDH public key cryptography for protection against
passive eavesdropping. For BT Classic only.

BT spec. For BT Classic only.
Security Mode 4: Simple Secure Pairing
Passkey Entry Just Works
Need to input PIN code when connecting to the
printer (default PIN is 0000). PIN can be updated
via bluetooth.bluetooth_pin SGD.
The SSP mode is usually negotiated automatically based on the capabilities of both the central and
peripheral. Lower security modes can be disabled via the
bluetooth.minimum_security_mode SGD sets the lowest security level at which the printer will establish a
Bluetooth connection. The printer will always connect at a higher security level if requested by the central
device. To change the security mode and security settings in the printers, use ZR1 Mobile Configuration
Tool.
Designed for situation where one (or both) of the
pairing devices has neither a display nor keyboard
for entering digits (e.g. Bluetooth headset). It
performs authentication step 1 in the same manner
as numeric comparison, but the user cannot verify
that both values match, so MITM
(man-in-the-middle) protection is not provided.
This is the only model in SSP that does not provide
authenticated link keys.

IMPORTANT: bluetooth.minimum_security_mode sets the lowest security level at which the printer will
establish a Bluetooth connection. The printer will always connect at a higher security level if requested by
the master device.
The printers also feature bonding for Bluetooth. The printer caches pairing info so devices stay paired
through power cycles and disconnects. This eliminates the need to repair on every connection
establishment.
The bluetooth.bonding SGD is always on but this SGD is not supported.
NOTE: For detailed information on Bluetooth, please refer to the Bluetooth Wireless User Guide at:
zebra.com/us/en/support-downloads.html
In addition, the printers support a “scan and pair” function via a handheld device and the MAC address
label on the bottom of the printer (see Figure 5). The printer also features passive NFC technology. Using
the “Print Touch” feature located on the top of the printer, end-users can automatically pair with a handheld
device that supports NFC technology. The NFC tag has the printer’s BDADDR encoded in a URL on the
tag. Simply touching the NFC handheld device to the “Print Touch” icon on the printer will connect and pair
the handheld device to the printer.

Using Near Field Communication (NFC)
Near Field Communication (NFC) allows wireless communication and data exchange between digital
devices such as this printer and a smartphone by using electromagnetic radio fields, while technologies
such as Bluetooth use radio transmissions instead.
NFC is a sub-class of Radio Frequency Identification (RFID) technology that is designed for use by
devices within close proximity to each other. NFC technology allows devices to establish communication
by touching or bringing them into close proximity, usually no more than 7.62 cm (3 in.).
The printer contains a passive NFC device which contains information that other devices can read but
does not read any information itself.
An active device, such as a smartphone, can read the information on the printer’s NFC tag, but the tag
itself does nothing except transmit the info to authorized devices.
Active devices can read information and send data. An active NFC device, such as a smartphone, would
not only be able to collect information from NFC tags, but it would also be able to exchange information
with other compatible phones or devices. An active device could even alter the information on the NFC tag
if authorized to make such changes. To ensure security, NFC often establishes a secure channel and uses
encryption when sending sensitive information.
Figure 12 NFC Pairing
NFC Use Cases
Passive
• Bluetooth Pairing – used to cause a tablet, smart phone or terminal to automatically pair with the printer
via a Bluetooth connection, within the bounds of the security profile being used. This shall contain the
BT address and serial number of the printer.
• App launching – used to cause an app, developed either by Zebra or a third party, to be executed on a
smartphone, tablet or terminal.
34
Using the Printer
• Web site launching – used to cause a smart phone, tablet or terminal to display a web site developed by
Zebra or a third party developer.
Tapping the Zebra Print Touch icon with an NFC-enabled smartphone will provide instant access to
printer-specific information. For more information about NFC and Zebra produncts, go to zebra.com/nfc
Bluetooth pairing applications via NFC is also possible. Please see Zebra Multi-platform SDK for more
information.

Preventive Maintenance
Extending Battery Life
• Never expose the battery to direct sunlight or temperatures over 40°C (104°F) when charging.
• Always use a Zebra charger designed specifically for Lithium-Ion batteries. Any other kind of charger
may damage the battery.
• Use the correct media for your printing requirements. An authorized Zebra re-seller can help you
determine the optimum media for your application.
• Consider using a pre-printed label if you print the same text or graphic on every label.
• Choose the correct print darkness, and print speed for your media.
• Use software handshaking (XON/XOFF) whenever possible.
• Remove the battery if the printer won’t be used for a day or more and you’re not performing a
maintenance charge.
• Consider purchasing an extra battery.
• Remember that any rechargeable battery will lose its ability to maintain a charge over time. It can only
be recharged a finite number of times before it must be replaced. Always dispose of batteries properly.
See Battery and Product Disposal on page 54 for more information on battery disposal.

Troubleshooting Tests
Printing a Configuration Label
To print out a listing of the printer’s current configuration follow these steps:
1. Turn the printer off. Load the media compartment with journal media (media with no black bars printed
on the back).
2. Press and hold Media Feed.
Troubleshooting
3. Press and release Power and keep Media Feed pressed. When printing starts, release Media Feed.
Refer to Figure 14 on page 45 for sample configuration printouts.
Communications Diagnostics
If there is a problem transferring data between the computer and the printer, try putting the printer in the
Communications Diagnostics Mode (also referred to as the “DUMP” mode). The printer will print the ASCII
characters and their text representation (or the period ‘.’, if not a printable character) for any data received
from the host computer.
To enter Communications Diagnostics Mode:
1. Print a configuration label.
2. At the end of the diagnostics report, the printer will print: “Press Media Feed to enter DUMP mode”.
3. Press Media Feed. The printer will print: “Entering DUMP mode”.
NOTE: If Media Feed is not pressed within three seconds, the printer will print “DUMP mode not entered”
and will resume normal operation.
At this point, the printer is in DUMP mode and will print the ASCII hex codes of any data sent to it, and their
text representation (or “.” if not a printable character).
Additionally, a file with a “.dmp” extension containing the ASCII information is created and stored in the
printer’s memory. It can be viewed, “cloned” or deleted using the Net Bridge application. (Refer to the
ZebraNet Bridge Enterprise documentation for more information.)
To terminate the Communications Diagnostics Mode and return the printer to normal operations:
1. Turn the printer OFF.
2. Wait five seconds.
3. Turn the printer ON.
