2 Update Firmware Update Firmware via the USB Host
Caution: Do not open the print module, disconnect your printer from the
computer or cut your printer power during the firmware update.
Caution: Do not remove the USB flash drive during the transmission.
2 Update Firmware
Firmware is the code stored permanently in hardware. It instructs your printer to
do its tasks. Benefits of updating firmware include new features, enhanced
functionality and improved performance.
2.1 Update Firmware via the USB Host
The USB host is a USB type A port for a USB flash drive, which can be used to
quickly update the firmware.
1. Take an USB flash drive and format file system to FAT32. Create a folder named
“Firmware” in your USB flash drive, and copy the firmware files to it. The file
“XXX-master.abin” needs to be in the folder.
Note The firmware file name must match to your printer.
2. Make sure the print module is closed, and turn off your printer.
3. Turn ON the printer power (or reboot the printer) after insert your USB flash
drive to the printer. The printer starts to transmit the firmware when LED is
green and blinking alternately.
4. When LEDs are all green, turn off the printer power, then remove USB flash
drive.
5. Update firmware success.

rare cases Printer Tool cannot handle. If any unexpected conditions keep you from
update firmware in Printer Tool, you need to update it in Atmel mode.
Step 1. Enter Atmel Mode
This part describes how to enter Atmel mode.
1. Turn off your printer.
2. Turn over your printer.
3. Loosen and remove 3 screws from the base.
4. Lift the base and unplug all the cables.

position (down).
Step 2. Update your firmware
This part describes how to update your firmware in Atmel mode.
1. Turn on your printer. Both LEDs won’t glow. This is normal.
2. Start Printer Tool. In the Navigation pane, click Download, and click the
Firmware tab.
23
2 Update Firmware Update Firmware in Atmel Mode
3. Right-click in the blank area and click Add.
24
2 Update Firmware Update Firmware in Atmel Mode
4. In the Open dialog box, browse to the folder that contains the firmware files.
Select all of them and click Open.
5. Right-click in the blank area in the list, and click Select All to select all of the
check boxes.
Note If you want to execute a firmware file without saving it into the flash
memory, select the Download to memory and execute check box and click
Send.
25
2 Update Firmware Update Firmware in Atmel Mode
6. Click Send to send the firmware files to your printer. When the update is
complete, the message “Done” appears. Click Close to close the dialog box, or
click Save Log to save the firmware update log.
Step 3. Exit Atmel Mode
This part describes how to exit Atmel mode.
1. Turn off your printer.
2. Set DIP Switch 1 and 2 to the ON position (up). If it’s inconvenient to set DIP
Switch while cables are connected, unplug all the cables to do this.

3 Network Network architecture
3 Network
This chapter provides the information about your printer networking.
3.1 Network architecture
As the figure shows, the network architecture includes several layers, and each
layer corresponds to the layer in the Open Systems Interconnection (OSI) model.
The print engine is on the application layer. It is a set of programs that handle
most jobs for your printer, such as receiving data, analyzing data, drawing images,
printing images and returning status. It communicates with TCP via the socket.
The socket is on the session layer. It is an application program interface (API) that
opens, receives, sends and closes TCP sessions between your printer and network
nodes to exchange data.
Transmission Control Protocol (TCP) and Internet Protocol (IP) are on the transport
and the network layer, respectively. These two layers work closely together. The
transport layer secures end-to-end data transfer by establishing a reliable
connection that includes features such as packet resend control, packet order
control, flow control and error checking. TCP is the protocol commonly used in
transport layer.
27
3 Network Network architecture
IP is the commonly used protocol in the network layer. It defines an address
system and provides end-to-end communication for data transmission. The packet
is delivered based on the IP address in the IP header, which is attached to the
packet. However, the packet may be lost, corrupted or out-of-order when it travels
across the network, because IP doesn’t ensure the delivery. TCP can prevent most
of these things happen.
The data link is on the data link layer. Its task is to create and manage a reliable
data transmission between two adjacent nodes in a network via MAC addresses. It
divides the data from the network layer into bits, encodes these bits into frames
prior to transmission, and decodes them at the destination. The data link also
provides the error control and flow control. The error control uses a frame check
sequence (FCS) to ensure that the delivered frames are intact, and the flow
control ensures that the fast sender doesn’t overwhelm the slow receiver with
data.
This architecture allows up to five computers to connect to a printer via the same
port. When you turn on your printer, it opens the maximum number of ports, and
is waiting for a session request. Once your printer receives a request, it establishes
a session and set it as “connected." If all of the sessions are occupied, no more
connection is allowed. In this case, your printer returns the RST signal to the
computer that made a request via the TCP protocol. When your printer finishes its
communication with the computer, it releases the session to get ready for a new
connection.
Data processing is determined by the connection priority. When your printer
connects to multiple computers, it only processes the data from the oldest session
(the first connected computer). The connection priority changes when there is a
disconnection. Other computer needs to wait until its session becomes the oldest.

Thermal Printhead (TPH)
It consists of a line of tiny resistors that is electronically controlled to produce heat
for printing. For direct thermal printing, a TPH directly heats up an area of the
thermal paper to produce an image.
Stepper Motor
A stepper motor rotates certain degrees in each step-in response to an electronic
pulse.
Cutter or Peeler (Option)
A cutter is a guillotine cutter which automatically cuts the printed label. There are
two cutting types: full and partial. A peeler automatically removes the liner from a
printed label. The sensor on the peeler detects if the peeled label is taken away.

5 Technical Drawings System Diagram
Microcontroller (U11)
The microcontroller (MCU) is AT91SAM9260. The MCU is like a microcomputer
which integrates CPU, memory, I/O ports, timers and other components. The CPU
it uses is ARM926-based processor.
Flash memory (U14)
The flash memory stores firmware, graphics, label formats, soft fonts and BASIC
files.
SDRAM (U17)
SDRAM is volatile memory, typically storing working buffers and parameters. After
the power is turned off, all of the data is gone.
Power (U13, U15, U19)
A regulator converts 24V DC to 5V DC as the VCC source for most of components
on main board. LDOs are 5V to 3.3V for I/O, 3.3V to 1.8V for CPU core.
Motor Driver (U2)
The motor driver is BD63877. It acts as an amplifier, which takes low-current
signals and generates high-current signals. Since the motor typically requires
voltages or currents that exceed what the circuitry can provide, the motor driver is
capable of providing higher voltages or currents for the motor.
Ethernet PHY
It is used to send and receive Ethernet frames. It complies with the IEEE 802.3
specifications for 10BASE-T and 100BASE-TX.
