Storage humidity
(1) Scope of this document
This document applies to the EU-m30 and bezel option OT-BU30.
(2) Product safety precautions
1) Do not allow a voltage that exceeds the absolute maximum rating to be applied to the power connector.
If the applied voltage exceeds the absolute maximum rating, excess current may flow, causing thermal damage
to components.
OUTLINE

3) Do not create short circuits between connector terminals in the printer unit.
Do not create short circuits between power connector terminals.
A short circuit to a low-impedance power supply can create excess current, causing thermal damage to
components.
4) During transport and storage, properly protect printer unit exterior (exposed) circuit boards and electronic
components with conductive sponges, aluminum foil, and such.
5) Do not drop clips and other conductive materials onto the printer unit's circuit board.
Short circuits between component connectors (terminals) can create excess current, causing thermal damage
to components.
6) Use only the cables indicated in this document. Also, use only the wiring indicated in this document.
Wiring done incorrectly can lead to a failure, fire, explosion, or other accident.
7) Do not disassemble or modify. Such actions can lead to injury or electric shock.
8) During operation, do not directly touch gears or other moving parts. You can get cut or otherwise injured.
9) Do not install in an unstable location (such as on an unsteady pedestal or sloping area). The product can
fall and you can get injured.
10) Do not install in a damp or dusty location. Also, ensure that the product is not exposed to water droplets.
Failure to do so may result in product failure, fire, or electric shock.
11) If the product will not be used for a long period, be sure to turn off the power to the printer unit for safety.

1 GENERAL SPECIFICATIONS
1.1 Print Specifications
(1) Print speed
The maximum is 100 mm/s {3.94"/s} when printing ladder bar codes, 2-dimensional symbols, or multi-tone
graphics.
The print speed changes automatically depending on the voltage applied to the printer and the condition of the
head temperature.
Maximum print speed may not be achieved depending on the data transmission conditions and the combination
of commands.
If the print speed fluctuates or intermittent printing occurs due to the data transmission conditions, printing
may be shaded or white lines may occur.
(2) Multi-tone graphics printing and limitations
Multi-tone graphics printing is possible (up to 16 tones when using our specified paper).
Multi-tone printing is not supported in Page mode.
Voids (white spaces) may appear depending on the paper type (uneven application of chromogenic coating).
It may not be possible to recreate an original image because a certain density level cannot be achieved due to th
following causes:
Environmental temperature, power supply and voltage
Paper type (chromogenic characteristics)
Paper variations, such as variations among manufacturing lots
Printing pattern (effect of heat accumulation of the print head or of voltage drop/speed change due to high
duty)
For multi-tone printing, the preservative quality of materials printed using multi-tone printing decreases in
direct relationship with the lighter the printing. Accordingly, do not use multi-tone printing when preservative
quality is required.
Reading quality of bar codes/2-dimensional symbols in multi-tone graphics printing is not guaranteed.
e
1.2 Character Specifications
Can be changed via the software settings.
For details, see 3.8.3 Software setting mode.
1.3 Autocutter
The cut paper may be pulled at the cut edge when it is removed, causing reduced printing pitch for the first line
o
f the next receipt.
To prevent dot displacement, after cutting, feed the paper approximately 1 mm {16/406"} or more before the firs
l
ine of printing. This operation can be enabled by enabling the pre-feed before next print, or by setting the top
margin specification via backfeed to 8.5 to 2 mm.
For the setting method, see 3.5.2. Software setting.
When issuing paper whose vertical length is short, ensure at least 20 mm.

(3) Print density adjustment depending on the specified original paper
In order to ensure optimal print quality and reliability, we recommend using the print density settings in the
table below.
The initial setting is 100% print density.
The print density can be changed using customized values.
When the print density setting is too dark, the print speed tends to drop.
When the print density setting is too dark, paper dust sticks to the print head surface, often resulting in faded
print.

(4) Notes on preprinting
Preprinted thermal paper may cause faulty printing and decreased print density due to the thermal head sticking
to the recording surface. Therefore, it is preferable to avoid using preprinted thermal paper.
If using preprinted thermal paper, make sure in advance that the conditions recommended by the original paper
manufacturing company (type of ink, print conditions, etc.) are met, and that there is no faulty printing or
decreased print density in the actual usage environment.

Note:
Printing with this product is assumed to be receipts or the equivalent. If printing is continuously performed
with a high print ratio, the overcurrent limitation may be operated. Therefore, the printing length must not
exceed 20mm {0.79"} when printing with 100% print ratio.

(2) USB communication specifications
(a) USB functions
Overall specifications: Complies with USB 2.0
Communication speed: Full-Speed (12 Mbps)
Communication method: USB bulk transmission method
Power supply specifications: USB self power supply function
Current consumed by USB bus: 2 mA (provided entirely from the main unit)
USB packet size
With full-speed connection
USB bulk OUT: 64 bytes
USB bulk IN: 64 bytes
USB device class
USB vendor-defined class and USB printer class
Switching of the class can be set by the software settings on startup.
(For the setting method, see 3.5.2.)
(b) Receiving the status from the printer
The status of the printer is sent to the host computer via the USB bulk transmission method.
The USB bulk transmission method is a host-controlled transmission method. Unlike RS-232 transmission,
it cannot spontaneously interrupt data transmission to the host computer.
The printer has a 128-byte status data buffer. Statuses that exceed the buffer capacity are canceled. In
order to avoid lack of status data, it is necessary to periodically retrieve status data at the host computer.
(c) USB Device Requests of USB printer class
GET PORT STATUS
If this USB device request is requested, the printer returns the following statuses.
5 Paper Empty
3 Not Error
16
GET DEVICE ID
If this USB Device Request is requested, the printer returns the following character string.
[00H][XXH] *1
MFG:EPSON;
CMD:ESC/POS;
MDL:EU-m30; *2
CLS:PRINTER;
DES:EPSON[SP]EU-m30; *2
CID:EpsonTM00001021; *2
*1: DeviceID character string size
*2: The character string depends on the language model and mode.
SOFT RESET
The host computer uses this USB Device Request when initializing the printer input buffer.
(3) Notes
Use a cable that complies with the USB 2.0 standard.

The stop bit for data transfer from the printer is fixed at 1 bit.
(3) Online/Offline switching
This printer does not have an online/offline switch. This printer goes offline under the following conditions:
During the period from when the power is turned on until the printer is ready to receive data after
mechanism initialization
During a self-test
When the cover is open
Feeding paper via Feed switch
When the printer stops printing due to a paper-end (when a paper-end is detected by the roll paper-end
sensor)
When waiting for a switch to be pressed during macro execution
When an error has occurred

(1) During the period from when the
power is turned on until the printer
is ready to receive data after
mechanism initialization
(2) During a self-test
(3) When the cover is open

When XON/XOFF control is selected:
The signal indicates whether the printer is correctly connected and is
ready to receive data from the host computer.
SPACE indicates that the printer is correctly connected and is ready to
receive data from the host computer. The signal is always SPACE
except in the following cases:
• During the period from when the power is turned on until the
printer is ready to receive data after mechanism initialization
• During a self-test
5 SG – Signal ground
6 DSR Input This signal indicates whether the host computer can receive data.
SPACE indicates that the host computer can receive data, and MARK
indicates that the host computer cannot receive data. When DTR/DSR
control is selected, the printer transmits data after confirming this signal
(except when transmitting data by DLE EOT or GS a).
When XON/XOFF control is selected, the printer does not check this
signal.
