combination of control commands.
3. Low transmission speed may cause intermittent printing. It is recommended to transmit
data to the printer as fast as possible.

6) Notes on preprinting on the recording surface of thermal paper
When using thermal paper, the recording surface of which has been preprinted, sticking (a
problem of the thermal head sticking to the surface of the thermal paper during printing) may
occur, causing faulty printing and other problems. It is, therefore, strongly recommended to
avoid using preprinted thermal paper. If such paper must be used, conduct preprinting tests
under the conditions recommended by the paper manufacturer (type of ink/print conditions) and
confirm that no faulty printing or any other problems occur before you use it for actual printing.

*1 • Definition of “receive buffer full”
• When the receive buffer capacity is specified to 4 KB (DIP SW1-2 is Off):
• If the DIP SW2-5 is off, when the remaining space in the receive buffer drops to 128 bytes,
the printer status becomes “buffer full” and it remains “buffer full” until the space in the
receive buffer increases to 256 bytes.
• If the DIP SW2-5 is on, when the remaining space in the receive buffer drops to 128 bytes,
the printer status becomes “buffer full” and it remains “buffer full” until the space in the
receive buffer increases to 138 bytes.
• When the receive buffer capacity is specified to 45 bytes (DIP SW1-2 is On):
• Regardless of the DIP SW2-5 setting, when the remaining space in the receive buffer
drops to 16 bytes, the printer status becomes “buffer full” and it remains “buffer full” until
the space in the receive buffer increases to 26 bytes.
• The printer ignores the data received when the remaining space in the receive buffer
is 0 bytes.
2.1.1.4 XON/XOFF transmit timing
When XON/XOFF control is selected, the printer transmits XON or XOFF signals as follows.

2.1.1.6 Notes on setting DIP switch 2-1 to ON
1) The printer mechanism stops but does not become busy when: an error has occurred, the cover is
open, printing stops due to a paper-end, or paper is fed using the paper feed button.
2) When setting DIP switch 2-1 to ON to enable handshaking with the printer, be sure to check the
printer status using the GS a command and the ASB function. In this setting, the default value of
n for GS a is 2. The printer automatically transmits the printer status, depending on online/offline
changes.
3) When using DLE EOT, DLE ENQ, and DLE DC4 be sure that the receive buffer does not become
full.
• When using a host that cannot transmit data when the printer is busy:
If an error has occurred, DLE EOT, DLE ENQ, and DLE DC4 cannot be used when the
printer is busy due to a receive buffer-full state.
• When using a host that can transmit data when the printer is busy:
When the receive buffer becomes full while transmitting bit-image data, DLE EOT, DLE ENQ
or DLE DC4 used while sending the bit-image data is processed as bit-image data. The
data transmitted when the receive buffer is full may be lost.
Example: Check the printer status using GS r after transmitting each line of data and use
the 4 KB receive buffer. Transmit one line of data so that the receive buffer
does not become full.

With this interface, the status of the printer is transmitted to the host computer via the USB bulk
transmission method.
The USB bulk transmission method is a host-controlled transmission method. Unlike RS232
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
cancelled. In order to ensure that there is no lack of status data, it is necessary to
periodically retrieve status data at the host computer.

3.9 Cover Open Sensor
The cover open sensor monitors the printer cover. When the sensor detects a cover open during
printing, the error LED flashes and the printer stops printing. The printer recovers when the cover is
closed. When the sensor detects a cover open while the printer is in the standby status, the printer
goes offline. The printer recovers when the cover is closed.
NOTE: Whether the cover is open or not does not affect the status reported by the roll paper end
sensor.
3.10 Print Buffer-full Printing
• When printing in standard mode
When subsequent data is received after the printer processes one line of data in the print buffer, the
printer automatically prints the processed line and feeds the paper by one line (in standard mode).
• When printing in page mode
When subsequent data is received after the printer processes one line of data in the print buffer, the
printer automatically moves the printing position to the line after the processed one.

16777216) to (nL + nH × 256) bytes in the NV user memory.
[Notes]
• Frequent write command executions by an NV memory write command may damage
the NV memory. Therefore, it is recommended to write to the NV memory less than
10 times a day.
• If the power is turned off or the printer is reset via an interface while this command is
being executed, the printer may go into an abnormal condition. Be careful not to
turn the power off or let the printer be reset via an interface while this command is
being executed.
• While processing this command, the printer is BUSY while writing data to the NV
memory and stops receiving data. Therefore, be sure not to transmit data, including
the real-time commands while the printer is BUSY.

[Notes]
• Frequent write command executions by an NV memory write command may damage
the NV memory. Therefore, it is recommended to write to the NV memory less than
10 times a day.
• If the power is turned off or the printer is reset via an interface while this command is
being executed, the printer may go into an abnormal condition. Be careful not to
turn the power off or let the printer be reset via an interface while this command is
being executed.
• While processing this command, the printer is BUSY while writing the data to the NV
memory and stops receiving data. Therefore, be sure not to transmit data, including
the real-time commands, while the printer is BUSY.
• When <Function 48, 51, or 64> is transmitted, the data following must not be
transmitted until the status is received. And, it will be necessary to perform the
ESC/POS Handshaking Protocol procedures when using <Function 64>.

the NV memory. Therefore, it is recommended to write to the NV memory less than
10 times a day.
• If the power is turned off or the printer is reset via an interface while this command is
being executed, the printer may go into an abnormal condition. Be careful not to
turn the power off or let the printer be reset via an interface while this command is
being executed.
• While processing this command, the printer is BUSY while writing the data to the NV
memory and stops receiving data. Therefore, be sure not to transmit data, including

APPENDIX A: MISCELLANEOUS NOTES
A.1 Notes on Printing and Paper Feeding
1) Because the TM-T81 printer is a line printer, it automatically feeds paper after printing the data.
Therefore, when the line spacing for one line is set to a smaller value than the print data, paper
may be fed more than the set amount just to print the data.
For example, when the line spacing for one line is set to 10 dots (10/180 inches) and only paper
feeding is executed, paper is fed for 10 dots; however, if bit-image characters are printed, paper
is fed for 24 dots. (See Table A.1.)
When only rotated characters are printed on one line, paper feeding is executed as shown in
Table A.1.
Table A.1
Normal Characters
Rotated Characters
Font A
Paper Feeding Amount
Required Paper Feeding Amount (dots)

Font B
17 × number of times enlarged in vertical
Font A
12 × number of times enlarged in vertical
Font B
9 × number of times enlarged in vertical
24
Bit image (ESC ∗)
2) When the printer goes to the standby (data-waiting) state during printing, it temporarily stops
printing and feeding paper. When data is transmitted and printing is executed, paper may shift
1 to 3 dots from the print starting position, which especially affects bit-image printing.
3) Interval of autocutting operation in the receipt section
For driving the auto cutter of the receipt section, take the interval as a minimum of 10 lines of
printing or paper feeding (to prevent small pieces of cut paper from dropping into the auto cutter).

A.2 Notes on Supplying the Power to the Printer
• Connect the external power supply to the power supply connector of the printer. Then plug in the
external power supply and turn it on if necessary. Be sure not to connect the external power
supply with the wrong polarity. If it is connected incorrectly, the internal circuit fuse of the printer
may be blown or the external power supply may be damaged.
• The power supply voltage is within the range of 24 V ± 7%. If the power supply voltage drops to
the outside of the range above during printing, the printer stops printing and waits until the
voltage returns to normal and then automatically begins printing again. Therefore, printing speed
may slow, the print pitch may not be correct, and some dots in some characters may not be
printed.
• Both high and low voltage errors are shown in table 3.7.3. The flashing patterns are shown in the
table.
• When either a high or low voltage error occurs, turn off the power as soon as possible.
A.3 Notes on use environment
Using in the presence of silicon gas (silicon adhesive, silicon oil, silicon powder, etc.) including
siloxane and of malignant gas (nitric acid, hydrosulfuric, ammonia, chlorine, etc.) may cause
contact failure at contact points in a mechanical switch and a DC motor etc. in a short time
because of adhesion or oxidization of the insulation film.

A.4 Other Notes
1) Printer mechanism handling
• Do not pull the paper out when the cover is closed.
• Because the thermal elements of the print head and driver IC are easy to break, do not touch
them with any metal objects.
• Since the areas around the print head become very hot during and just after printing, do not touch
them.
• Do not use the cover open button except when necessary.
• Do not touch the surface of the print head because dust and dirt can stick to the surface and
damage the elements.
+
+
• Thermal paper containing Na , K , and Cl ions can harm the print head thermal elements.
Therefore, be sure to use only the specified paper.
• Label paper cannot be used.
2) Thermal paper handling
Notes on using thermal paper
Chemicals and oil on thermal paper may cause discoloration and faded printing. Therefore,
pay attention to the following:
a) Use water paste, starch paste, polyvinyl paste, or CMC paste when gluing thermal paper.
b) Volatile organic solvents such as alcohol, ester, and ketone can cause discoloration.
c) Some adhesive tapes may cause discoloration or faded printing.
d) If thermal paper touches anything which includes phthalic acid ester plasticizer for a long
time, it can reduce the image formation ability of the paper and can cause the printed
image to fade. Therefore, when storing thermal paper in a card case or sample
notebook, be sure to use only products made from polyethylene, polypropylene, or
polyester.
e) If thermal paper touches diazo copy paper immediately after copying, the printed surface
may be discolored.
f) Thermal paper must not be stored with the printed surfaces against each other because
the printing may be transferred between the surfaces.
g) If the surface of thermal paper is scratched with a hard metal object such as a nail, the
paper may become discolored.
Notes on thermal paper storage
Since color development begins at 70°C {158°F}, thermal paper should be protected from high
temperature, humidity, and light, both before and after printing.
a) Store paper away from high temperature and humidity.
Do not store thermal paper near a heater or in enclosed places exposed to direct sunlight.
b) Avoid direct light.
Extended exposure to direct light may cause discoloration or faded printing.

APPENDIX C: RECOVERY FROM THE AUTO CUTTER ERROR
• If a foreign object such as a push pin or paper clip drops in the auto cutter and causes the auto
cutter to lock up, the printer enters an error state and begins the recovery operation automatically.
(The error LED flashes continuously, but it is possible for the error to be corrected automatically.)
If the problem is not serious, the auto cutter returns to its normal position without any intervention
by the user.
If the auto cutter does not return to its normal position by itself, follow the steps below to correct
the problem:
1) Pull the cutter cover toward you and remove it so that you can rotate the cutter motor
knob.
2) Rotate the cutter motor knob to the direction indicated by an arrow on the autocutter unit.
3) Following the instructions on the caution label, rotate the knob until the indicator ▼
appears in the hole.
• If the motor knob cannot be rotated, rotate it in the reverse direction to loosen it; then send the
DLE ENQ n command. Next, check the ERROR LED. If the ERROR LED is not off, repeat the
same procedure and confirm that the ERROR LED is off. When the ERROR LED is off, the auto
cutter blade has returned to its normal position and the roll paper cover can be opened. Open
the roll paper cover, remove the jammed paper, and reinstall the roll paper. Then close the roll
paper cover.

APPENDIX D: ADJUSTING THE PAPER ROLL NEAR-END SENSOR
LOCATION
The remaining detectable amount of paper on the roll paper varies with the inside and outside
diameters of the paper core. The minimum detectable amount of paper on the roll paper can be set
using the following method:
1) The inside diameter of the paper spool should be 12mm {0.47"} and the outside diameter of the
paper spool should be 18mm {0.71"}. Specified thermal paper should be used.
2) Loosen the adjusting screw that holds the paper near-end sensor and set the top of the
positioning plate to the appropriate adjustment value and tighten the adjusting screw.
Adjust the positioning plate to #1 if the outside diameter of a roll paper to be used is 18mm.
Adjust the positioning plate to #2 if the outside diameter of a roll paper to be used is more than
18 mm.

APPENDIX F: NOTES ON USING THE DRAWER KICK-OUT
CONNECTOR
1) Drawer specifications (see Section 2.2.3, Drawer kick-out connector)
Drawer specifications differ significantly depending on manufacturer and model number. Make
sure that the specifications of the drawer used meet the following conditions when connected to the
drawer kick-out connector. These conditions also apply to any equipment (other than a drawer)
that is connected to the drawer kick-out connector.
Never use a drawer (or other equipment) that does not meet all of the following conditions:
• The load, such as a drawer kick-out solenoid, must be connected between pins 4 and 2 or pins
4 and 5 of the drawer kick-out connector. (*1)
• When the drawer open/close signal (indicating the state of the drawer) is used, a switch must
be provided between drawer kick-out connector pins 3 and 6. (*2)
• The resistance of the load, such as a drawer kick-out solenoid, must be 24 Ω or more or the
input current must be 1A or less. (*3)
• Make sure to use the 24 V power output on drawer kick-out connector pin 4 for driving the
equipment. Never connect any other power supply to the drawer kick-out connector. (*4)
The peak current is 1 A. See item 2) below for drive signal duty.
NOTES: (*1): Proper operation is not guaranteed with different connections.
(*2): Proper operation is not guaranteed with different connections or connection to a
component other than a switch.
(*3): Connection to equipment whose resistance is 24 Ω or less or whose input current is 1 A
or more may damage the connected equipment as well as the printer.
(*4): Operation is not guaranteed with other power supplies.
2) Notes on the pulse generating command (ESC p)
When using ESC p to drive the drawer connected to the drawer kick-out connector, set the
command parameters to meet the following conditions:

The ON time depends on the specifications of the drawer used. Be sure to check the drawer
specifications and set a suitable time. To use a drawer that does not meet the conditions of
Formulas F-1 and F-2, see the following section.
3) Using a drawer that does not meet the conditions in 2) (ESC p, DLE DC4)
i. For ESC p
Setting the values of t1 and t2 according to the conditions in 2) results in a maximum ON time of
126 ms (0 ≤ t1 ≤ 63), since the setting ranges of t1 and t2 are 0 to 255. To use a drawer that
requires an ON time exceeding 126 ms, the following conditions must be met:
ON time
ON time + (OFF time + α)
≤ 0.2.................................Formula F-3
α:other sequence processing time
NOTE: α is the drawer-driving prohibited period from the OFF time until the next ON time.
ii. For DLE DC4
Since DLE DC4 sets ON time equals to OFF time, use α so that Formula F-3 is met.

APPENDIX G: NOTES ON UPDATING THE MAINTENANCE COUNTER
AND TURNING THE PRINTER’S POWER OFF
G.1 About updating the maintenance counter
• This printer has a maintenance counter function, as described in the command description for GS
g 0 and GS g 2.
• The values of the maintenance counter are automatically stored in the NV memory every 2
minutes (or 4 minutes maximum) when the printer is operating, except in the power save mode.
• However, if the power off is performed as described in Section G.2, the printer stores the latest
values of the maintenance counter and executes the power off control, regardless of the updating
interval described above.
• If the printer is not sending/receiving data or is not operating for two seconds while the power is
turned on, the printer enters the power-saving mode and all of the values of the maintenance
counter including the printer operation time stop counting.
G.2 Power off procedure by the host
The following is an example of the printer power off process when the printer is turned off using the
DLE DC4 (fn = 2) command.
1) The host transmits the following continuous procedure before the system is turned off:
cExecutes GS ( D pL pH m a b (pL=3, pH =0, m =20, a =2, b =1)
d Executes GS r n (n =1)
2) The host waits for the paper sensor status sent from the printer in response to the GS r n
command.
3) The host transmits DLE DC4 fn a b (fn =2, a =1, b =8).
4) The host waits for the power off status.
• The values of the maintenance counter are stored and the power-off sequence is performed
within 20 seconds after the host transmits DLE DC4 fn a b; then the power off status is
transmitted.
• For the USB interface model, the printer is required to be ready for receiving data from the
host.
• For the serial interface model, the printer status is transmitted regardless of the condition of
the host.
• For the parallel interface model, after the host transmits DLE DC4 fn a b, the printer is
required to be ready for receiving data from the host.
• If the power off status in not confirmed, wait for 20 seconds at least after transmitting DLE
DE4 fn a b.
NOTE: The printer executes the software sequence, but the power is not cut.
5) Please turn the host power off.
NOTE: Do not execute a reset to the printer until the printer power is turned off after transmitting
DLD DC4 (fn = 2).

APPENDIX H: NOTES ON PRINTING 2-DIMENSIONAL CODE
The TM-T81 supports 2-dimensional code printing.
Be sure to follow the notes below when printing 2-dimensional codes.
• When printing PDF417 (2-dimensional code), it is recommended to set the height of one module
of the symbol to three to five times the width of one module, also making sure that the total
height is almost 5 mm {0.20"} or more.
• The recognition rate of the 2-dimensional code may be affected by such items as different widths
of the modules, print density, environmental temperature, type of the thermal paper, and
characteristics of the reader. Therefore, the user should check the recognition rate in advance
so that the limitations of the reader can be considered.
APPENDIX I: NOTES ON SCANNING THE PRINT RESULT ON THE
RECEIPT
Take a consideration as described below to determine whether the ability of the reader (scanner) can
be satisfied when the print result on the receipt, such as bar code, 2-dimensional code, or characters.
1) Print density
The print density may vary depending on the type of roll paper or the environmental conditions.
2) Slant of the print result
The print result may be slant slightly as shown in Figure I-1. The slant angle of the print result is
within ±1.6° and it varies while printing or each receipt issue.
Figure I-1
Slant of the Print
NOTE: In case that the paper other than the paper described in Section 1.5 Paper Specification is
used or when the paper is used out of the range in Section 1.12 Environmental conditions,
the print density or the slant of print result may become widen.
