Operating Precautions

This section presents important information intended to
ensure safe and effective use of the printer. Please read the
following carefully.

Notes on Safety

Be sure to use the specified battery and power source
provided by our company. Connection to an improper power
source may cause fire, explosion or damage to the printer.

Don’t put the battery into the fire or water, don’t disassemble
or modify the battery, don’t be short circuit, otherwise may
result in injury or fire even explosion.

If the printer would not be used for a long time, be sure to
take off the battery, otherwise the battery may leak liquid
which is corrosive, if improper operation causes battery leak,
and the liquid is spattered on the skin or clothes, please wash
it with water, if spattered in the eyes, please rinse them with
water thoroughly and see a doctor.

Please do not open the paper case cover when it is printing
or just when printing is over, do not touch the print head with
hand or body, overheat may cause scald.

8

Notes on Using

Be sure not to print continuously over 1 meter, otherwise may
cause damage to the print head.

Water or other liquid should not spill into the printer, also the
printer should not be appeared in the rain, or else may cause
printer damage.
Please do not open the paper case cover when it is printing,
otherwise the printer may work improperly.

If print with serial interface, should not unplug the interface
cable in the course of printing, or else some printing data may
be lost.
When print in Ir or IrDA mode, be sure the Ir window of the
host equipment face rightly the Ir window of the printer, the
distance should be within the range of 50mm, and the angle
should be within the range of 30

o

.
When print with Bluetooth interface, the communication
distance should be within 10 meters, otherwise the printer
doesn’t print or prints rubbish codes.

Too high（45℃）or too low（5℃） temperature and too high
(85％)or too low (20％) relative humidity both effect the print
quality.
The print paper in poor quality or stored for too long time also

9

may reduce the print quality even damage the printer.

In the black mark detecting mode, the printer requires that
the ready-print black mark is accordant with the black mark
printing rules (details please refer to Chapter 5), otherwise
the black mark can not be detected correctly.

Be sure to use up the electricity of the battery before charge it,
as it can ensure the using life of the battery.

Notes on Handling

The printer should be placed in such an environment that the
temperature is between -20 and 60 , and the relative ℃℃
humidity is between 5% and 95%.

If the printer will be stored for a long time, pleas be sure to
take out the battery, otherwise may damage the battery and
printer.

When the Li battery is stored over 3 months,it shoud be taken
out to charge one time, in order to avoid the battery damage.

Normal thermal paper can’t be kept too long, if you need to
keep the receipt for a long period, please choose long term
effective thermal paper.
The print paper should be keep away from high temperature

10

environment and point-blank sunshine.

After the printer is used for a period of time, the power of
battery will be run out. When the battery is low, the power
indicator blinks with red color and the buzzer rings 3 times; if
the printer is in sleeping mode, the printer will cut off power
after the buzzer rings 3 times. In this case, you must charge
the battery by using the adaptor.
The charging method is as following: turn off the printer,
connect the adapter to the power socket with 220V, 50HZ,
then plug the power charging cable to the power socket of the
printer, so the power charging begins, during the course of
power charging, the charging indicator is on, and will be off
when the charging is over.
Notice: it would better not turn on the printer during the
course of charging power, lest the charging time goes longer,
moreover, be sure not to use the printer to print when the
battery is charging.

3.3 Communication Interface

3.3.1 RS-232 Serial Interface

The standard accessories for T8 printer include: DB-9 serial
interface cable (one end is D model standard serial interface
socket, connected to host computer, the other end is PS/2
socket, connected to printer).
When connect the serial interface, if it works normally, then
the printer stops to received data from Bluetooth, or IrDA

16

interface.
The specification of serial interface of T8 as below:

Data Transfer: Serial

Synchro Mode: asynchronous

Handshaking: Hardware RST/CTS or Xon/Xoff optional

User can change the settings by using the Setting Tool.

Definition for the PS/2 socket:

17

1.TXD: send data

2.DTR: ready signal

3.RXD: receive data

4.RTS: when the signal is “MARK”, means printer is busy,

can’t receive data; when the signal is “SPACE”, means the

printer is ready to receive data.

5.GND: ground

6.NC: reserved

3.3.2 IrDA Connection

The hardware of T8 with infrared port printer is compatible
with IrDA1.1. IrCOMM protocol is one of the sub-protocol of
IrDA and widely used in portable devices. RAW-Ir data
transmission mode can be connected to the devices with raw
infrared port for printing, while IrCOMM mode can be
connected to the devices with IrCOMM protocol for printing.
RAW-Ir can work under 9600bps, 19200bps, 38400bps,
57600bps, 115200bps, the baud rate of RAW-Ir is same to
that of serial interface.

Notice:

1) To use the T8’s infrared port, a computer or Personal
Digital Assistant (PDA) with IR port is required.

2) Position a PDA conforming to the specifications in point
not more than 50 centimeter away from the printer’s infrared

18

port. Make sure the two ports are in front of each other with
an angle of not more than 30° on the four side.

3.3.3 Bluetooth Connection

PDA, Laptop and other communication devices with
Bluetooth can drive T8-BT to print by the Bluetooth interface.
T8-BT is compatible with Bluetooth 2.0 protocol. Power grade
is CLASS 2; effective communication distance is 10 meters.
The name of the printer is T8 Bluetooth Printer, the initial
password is “1234”; users can change the printer name and
password by using Setting Tools.

Bluetooth Pairing:

The method for the pairing between T8-BT with the host
device is:

1. Turn on the printer;

2. Host device searches for the outer Bluetooth device;

3. If there are other Bluetooth devices, please select T8

Bluetooth Printer;

4. Put in password “1234”

5. Pairing finished.
Notice: If the printer name has been changed, please be sure
not turn on more than one printer, otherwise it will be difficult
to justify which printer been paired.

Binding of Address:

19

Binding: once the printer remembers the device’s address, it
only can connect with the device and can’t connect with
others. So in this case, if the printer needs to connect with
other device, user can delete the remembered address.
No binding: in this case, the printer can be searched or paired
by any other device. So when the printer needs to connect
with a fixed device, it would be better bind address.

3.4 Other Functions

3.4.1 Sleeping Mode

Sleeping: the printer will fall after at least 3 seconds without
usage into sleep, and the status indication becomes green;
also the printer can be awaken by sending command 0x00,
then send data, the time spacing is about 20ms.

3.4.2 Paper End Alarming

When the paper is run out, the buzzer of the printer will ring 2
times, informs the user to load paper.

3.4.3 Black Mark

Notes: some notes shall be paid attention to;
Reference: other commands which are relevant to it.

HT

[Name] Horizontal tab
[Format] ASCII HT

Hex 09

Decimal 9
[Description] Moves the print position to the next horizontal
tab position.
[Notes]

 　 This command is ignored unless the next horizontal tab

position has been set.

 If the next horizontal tab position exceeds the printing area, 　

22

the printer sets the printing position to [Printing area width +
1].

 Horizontal tab positions are set with 　 ESC D.
 If this command is received when the printing position is at

[printing area width+ 1], the printer executes print buffer-full
printing of the current line and horizontal tab processing from
the beginning of the next line.

 The default setting of 　 the horizontal tab position for the

paper roll is font A (12 24) every 8th character (9th, 17th, 　
25th, ... column).
[Reference] ESC D

LF

[Name] Print and line feed
[Format] ASCII LF

Hex 0A

Decimal 10
[Description] Prints the data in the print buffer and feeds one
line based on the current line spacing.
[Note] This command sets the print position to the beginning
of the line.
[Reference] ESC 2, ESC 3

FF

[Name] Print and return to standard mode in page mode
[Format] ASCII FF

23

Hex 0C

Decimal 12
[Description] Prints the data in the print buffer collectively and
returns to standard mode.
[Notes]

The buffer data is deleted after being printed.　
The printer does not execute paper cutting.　
This command sets the print position to the beginning of

the line.

This command is enabled only in page mode.　

[Reference] ESC FF, ESC L, ESC S

CR

[Name] Print and carriage return
[Format] ASCII CR

Hex 0D

Decimal 13
[Description] When automatic line feed is enabled, this
command functions the same as LF; when automatic line
feed is disabled, this command is ignored.
[Notes]

Sets the print starting position to the beginning of the line.　
The automatic line feed is ignored with a serial interface

model.

This command is set according to the DIP switch setting 　

with a parallel interface model.

24

[Reference] LF

CAN

[Name] Cancel print data in page mode
[Format] ASCII CAN

Hex 18

Decimal 24
[Description] In page mode, deletes all the print data in the
current printable area.
[Notes]

This com　 mand is enabled only in page mode.
If data that existed in the previously specified printing area

also exists in the currently specified printing area, it is
deleted.
[Reference] ESC L, ESC W

DLE EOT n

[Name] Real-time status transmission
[Format] ASCII DLE EOT n

Hex 10 04 n

Decimal 16 4 n
[Range] 1 n 4　　
[Description] Transmits the selected printer status specified
by n in real-time, according to the following parameters:

n = 1: Transmit printer status
n = 2: Transmit off-line status

25

n = 3: Transmit error status
n = 4: Transmit paper roll sensor status

[Notes]

The status is transmitted whenever the data sequence of 　

<10>H<04>H< n> (1 n 4) is　　 received.
Example:
In ESC m nL nH d1...dk, d1=<10>H, d2=<04>H, d3=<01>H

This command should not be used within the data 　

sequence of another command that consists of 2 or more
bytes.
Example:
If you attempt to transmit ESC 3 n to the printer, but DTR
(DSR for the host computer) goes to MARK before n is
transmitted and then DLE EOT 3 interrupts before n is
received, the code <10>H for DLE EOT 3 is processed
as the code for ESC 3 <10>H.

Even though the printer is not selected using 　 ESC = (select

peripheral device), this command is effective.

The printer transmits the current status. Each status is 　

represented by one byte data.

The printer transmits the status without confirming whether 　

the host computer can receive data.

The printer executes this c　 ommand upon receiving it.
This command is executed even when the printer is off　 -line,

the receive buffer is full, or there is an error status with a
serial interface model.

26

With a parallel interface model, this command can not be 　

executed when the printer is busy. This command is
executed even when the printer is off-line or there is an error
status when DIP switch 2-1 is on with a parallel interface
model.

When Auto Status Back (ASB) is enabled using the 　 GS a

command, the status transmitted by the DLE EOT command
and the ASB status must be differentiated. (Refer to
Appendix G, TRANSMISSION STATUS IDENTIFICATION)
n = 1: Printer status

n = 2: Off-line status

27

Bit 5: Becomes on when the paper end sensor detects paper
end and printing stops.
n = 3: Error status

28

Bit 3: If these errors occur due to paper jams or the like, it is
possible to recover by correcting the cause of the error and
executing DLE ENQ n (1 n 2). If an error　　 due to a circuit
failure (e.g. wire break) occurs, it is impossible to recover.
Bit 6: When printing is stopped due to high print head
temperature until the print head temperature drops
sufficiently or when the paper roll cover is open during
printing, bit 6 is On.
n = 4: Continuous paper sensor status

[Reference] DLE ENQ, GS a, GS r

DLE ENQ n

[Name] Real-time request to printer
[Format] ASCII DLE ENQ n

Hex 10 05 n
Decimal 16 5 n

[Range] 1 n 2　　

29

[Description] Responds to a request from the host computer.
n specifies the requests as follows:

[Notes]

This command is effective only when an auto　 -cutter error

occurs.

The printer starts processing data upon receiving this 　

command.

This 　 command is executed even when the printer is off-line,

the receive buffer is full, or there is an error status with a
serial interface model.

With a parallel interface model, this command can not be 　

executed when the printer is busy. This command is
executed even when the printer is off-line or there is an error
status when DIP switch 2-1 is on with a parallel interface
model.

The status is also transmitted whenever the data sequence 　

of <10>H<05>H< n> (1 n 2) is received.　　
Example:
In ESC m nL nH dk, d1 = <10>H, d2 = <05>H, d3 = <01>H

This command should not be contained within another 　

command that consists of two or more bytes.
Example:

30

If you attempt to transmit ESC 3 n to the printer, but DTR
(DSR for the host computer) goes to MARK before n is
transmitted, and DLE ENQ 2 interrupts before n is received,
the code <10>H for DLE ENQ 2 is processed as the code for
ESC 3 <10>H.

　DLE ENQ 2 enables the printer to recover from an error

after clearing the data in the receive buffer and the print
buffer. The printer retains the settings (by ESC !, ESC 3, etc.)
that were in effect when the error occurred. The printer can
be initialized completely by using this command and ESC @.
This command is enabled only for errors that have the
possibility of recovery, except for print head temperature
error.

When the printer is disabled with 　 ESC = (Select peripheral

device), the error recovery functions (DLE ENQ 1 and DLE
ENQ 2) are enabled, and the other functions are disabled.
[Reference] DLE EOT

DLE DC4 n m t

[Name] Generate Drawer kick-out on & off pulse at real-time
[Format] ASCII DLE DC4 n m t

Hex 10 14 n m t
Decimal 16 20 n m t

[Range] n = 1; m = 0, 1; 1 t 6　　
[Description] Outputs the pulse specified by t to connector pin
m as follows:

31

The pulse ON time is [ t 100 ms] and the OFF time is [ t 　

100ms].　

[Notes]

When the printer is in an error status when this command 　

is processed, this command is ignored.

When the pulse is output to the connector pin s　 pecified

while ESC p or DEL DC4 is executed while this command is
processed, this command is ignored.

The printer executes this command upon receiving it.　
With a serial interface model, this command is executed

even when the printer is off-line, the receive buffer is full, or
there is an error status.

With a parallel interface model, this command cannot be 　

executed when the printer is busy. This command is
executed even when the printer is off-line or here is an error
status when DIP switch 2-1 is on.

If print data includes the same character strings as this 　

command, the printer performs the same operation specified
by this command. The user must consider this.

This command should not be used within the data 　

sequence of another command that consists of 2 or more
bytes.

32

This command is effective even when the printer is 　

disabled with ESC = (Select peripheral device).
[Reference] ESC p

ESC FF

[Name] Print data in page mode
[Format] ASCII ESC FF

Hex 1B 0C

Decimal 27 12
[Description] In page mode, prints all buffered data in the
printing area collectively.
[Notes]

This command is enabled only in page mode.　
After printing, the printer does not clear the buff　 ered data,

setting values for ESC T and ESC W, and the position for
buffering character data.
[Reference] FF, ESC L, ESC S

ESC SP n

[Name] Set right-side character spacing
[Format] ASCII ESC SP n

Hex 1B 20 n

Decimal 27 32 n
[Range] 0 n 255　　
[Description] Sets the character spacing for the right side of
the character to [ n horizontal or　 vertical motion units].

33

[Notes]

The right　 -side character spacing for double-width mode is

twice the normal value. When characters are enlarged, the
right-side character spacing is n times normal value.

This command does not affect the setting of 　

Chinese

characters.

This command sets values independently in each mode 　

(standard and page modes).

The horizontal and vertical motion unit are speci　 fied by GS

P. Changing the horizontal or vertical motion unit does not

affect the current right-side spacing.

The 　 GS P command can change the horizontal (and

vertical) motion unit. However, the value cannot be less than
the minimum horizontal movement amount, and it must be in
even units of the minimum horizontal movement amount.

In standard mode, the horizontal motion unit is used.　
In page mode, the horizontal or vertical motion unit differs

in page mode, depending on starting position of the printable

FS p n m

[Name] Print NV bit image
[Format] ASCII FS p n m

Hex 1C 70 n m
Decimal 28 112 n m

[Range] 1 n 255; 0 m 3 , 48 m 51　　 　　 　　
[Description] Prints a NV bit image n using the mode
specified by m.

n is the number of the NV bit image (defined using the 　 FS q

command).

m specifies the bit image mode.　

[Detail]

NV bit image means a bit image which is defined in a 　

non-volatile memory by FS q and printed by FS p.

72

This command is not effective when the specified NV bit 　

image has not been defined.

In standard mode, this command is effective only whe　 n

there is no data in the print buffer.

In page mode, this command is not effective.　
This command is not affected by print modes (emphasized,

double-strike, underline, character size, white/black reverse
printing, or 90 rotated characters, etc.), exce　 pt upside-down
printing mode.

If the printing area width set by 　 GS L and GS W for the NV

bit image is less than one vertical line, the following
processing is performed only on the line in question.
However, in NV bit image mode, one vertical line means 1
dot in normal mode (m 0, 48) and in double　 -height mode
(m 2, 50), and it means 2 dots in double　 -width mode (m 1,

49) and in quadruple mode (m 3, 51).　

The printing area width is extended to the right in NV bit ①

image mode up to one line vertically. In this case, printing
does not exceed the printable area.

If the printing area width cannot be extended by one line ②

vertically, the left margin is reduced to accommodate one line
vertically.

If the downloaded bit　 -image to be printed exceeds one line,

the excess data is not printed.

This command feeds dots (for the height n of the NV 　

bit-image) in normal and double-width modes, and (for the

73

height n 2 of the NV bit　 -image) in doubleheight and
quadruple modes, regardless of the line spacing specified by
ESC 2 or ESC 3.

After printing the bit image, this command sets the print 　

position to the beginning of the line and processes the data
that follows as normal data.

xL, xH specifies ( xL xH 256) 8 dots in the horizontal

74

direction for the NV bit image you are defining.

yL, yH specifies ( yL yH 256) 8 dots 　　　in the vertical

direction for the NV bit image you are defining.
[Notes]

Frequent write command execution may cause damage 　

the NV memory. Therefore, it is recommended to write the
NV memory 10 times or less a day.

The printer performs a hardware reset　 after the procedure

to place the image into the NV memory. Therefore,
user-defined characters, downloaded bit images, and macros
should be defined only after completing this command.
The printer clears the receive and print buffers and resets the
mode to the mode that was in effect at power on. At this time,
DIP switch settings are checked again.

This command cancels all NV bit images that have already 　

been defined by this command. The printer can not redefine
only one of several data definitions previously defined. In this
case, all data needs to be sent again.

From the beginning of the processing of this command till 　

the finish of hardware reset, mechanical operations (including
initializing the position of the printer head when the cover is
open, paper feeding by using the FEED button, etc.) cannot
be performed.

During processing this command, the printer is in BUSY 　

when writing the data to the user NV memory and stops
receiving data. Therefore it is prohibitted to transmit the data

75

including the real-time commands during the execution of this
command.

NV bit image means a bit image which is defined in a 　

non-volatile memory by FS q and printed by FS p.

In standard mode, this command is effective only when 　

processed at the beginning of the line.

　In page mode, this command is not effective.

This command is effective when 7 bytes <FS yH> is 　　

processed as a normal value.

When the amount of data exceeds the capacity left in the 　

range defined by xL, xH, yL, yH, the printer processes xL, xH,
yL, yH out of the defined range.

In the first group of NV bit images, when any of the 　

parameters xL, xH, yL, yH is out of the definition range, this
command is disabled.

In groups of NV bit images other than the first one, when 　

the printer processes xL, xH, yL, yH out of the defined range,
it stops processing this command and starts writing into the
NV images. At this time, NV bit images that haven’t been
defined are disabled (undefined), but any NV bit images
before that are enabled.

The d indicates the def　 inition data. In data ( d) a 1 bit

specifies a dot to be printed and a 0 bit specifies a dot not to
be printed.

This command defines n as the number of a NV bit image. 　

Numbers rise in order from NV bit image 01H. Therefore, the

76

first data group [xL xH yL yH d1...dk] is NV bit image 01H,
and the last data group [xL xH yL yH d1...dk] is NV bit image
n. The total agrees with the number of NV bit images
specified by command FS p.

A definition data of a NV bit image consists of [xL xH yL yH 　

d1...dk]. Therefore, when only one NV bit image is defined
n=1, the printer processes a data group [xL xH yL yH d1...dk]
once. The printer uses ([data: ( xL xH 256) ( yL yH 256)

8] [header :4]) bytes of NV memory.　
The definition area in this printer is a max　 imum of 2M bits

(256K bytes). This command can define several NV bit
images, but cannot define a bit image data whose total
capacity [bit image data header] exceeds 2M bytes (256K
bytes).

The printer is busy immediately before writing into NV 　

memory, regardless of the setting of DIP switch 2-1.

The printer does not transmit ASB status and perform 　

status detection during processing of this command even
when ASB is specified.

When this command is received during macro definition, 　

the printer ends macro definition, and begins performing this
command.

Once a NV bit image is defined, it is not erased by 　

performing ESC @, reset, and power off.

This command performs only definition of a NV bit image 　

and does not perform printing. Printing of the NV bit image is

77

performed by the FS p command.

When m = 0,48,1, 49, the printer feeds the paper to the 　

cutting position and cuts it.

When n = 66, the printer feeds the paper to (cutting 　

position + [ n vertical motion unit]) and cuts it.　

The horizontal and vertical motion unit 　 are specified by GS

P.

The paper feed amount is calculated using the vertical 　

motion unit (y). However, the value cannot be less than the
minimum horizontal movement amount, and it must be in
even units of the minimum horizontal movement amount.
