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.

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

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.

1.4 Paper Sensor

(1) Function

Detects whether paper is present in the paper path.

(2) Method

Microswitch

1.5 Roll Paper Supply Device

 Use roll paper that is not deformed, and ensure there is no slack when setting.

(1) Function

Supplies paper with a width of 80 mm {3.15"} or 58 mm {2.28"}

(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.

*1: Definition of “receive buffer full”

1) When the receive buffer capacity is specified as 4 KB (Memory switch 1-2 is off ):

(1) If Memory switch 5-2 is OFF:

The printer status becomes "buffer full" from when the remaining space in the receive buffer drops to 128 bytes until such time that the remaining space in the receive buffer increases to 256 bytes.

(2) If Memory switch 5-2 is ON:

The printer status becomes "buffer full" from when the remaining space in the receive buffer drops to 128 bytes until such time that the remaining space in the receive buffer increases to 138 bytes.

2) When the receive buffer capacity is specified as 45 bytes (Memory switch 1-2 is ON):

The printer status becomes "buffer full" from when the remaining space in the receive buffer drops to 16 bytes until such time that the remaining space in the receive buffer increases to 26 bytes regardless of the Memory switch 5-2 status.

 The printer ignores the data received when the remaining space in the receive buffer is 0 byte.

(5) XON/XOFF transmission timing

When XON/XOFF control is selected, the printer transmits an XON or XOFF signal at the timing shown below. The transmission timing differs depending on the Memory switch 1-3 setting.

Notes:

 Be careful that the status is not handshaking if connected to a DCE (data is discharged). (DCE: Data Circuit

Terminating Equipment)

 Transmit data to this printer after turning on the power and initializing the printer.

(7) Notes on setting Memory switch 1-3 to ON

1) Print operation stops but the status does not become busy when an error has occurred, the cover is open, printing stops due to a paper-end, or paper is fed by using the Feed switch.

2) When setting Memory switch 1-3 to ON to enable handshaking with the printer, be sure to check the printer

1 2 3

status using the GS a command and the automatic status back function of the data dependent on that command.

In this setting, the default value of n for GS a is 2. The printer automatically transmits the printer status when the online/offline status changes.

3) Be sure that the receive buffer does not become full when using DLE EOT, DLE ENQ, or DLE DC4.

 Notes on using a host computer that cannot transmit data when the printer is busy:

DLE EOT, DLE ENQ, and DLE DC4 cannot be used if an error occurs when the printer is busy due to a receive buffer-full status.

 Notes on using a host computer that can transmit data when the printer is busy:

A DLE EOT, DLE ENQ, or DLE DC4 command used while transmitting bit-image data is processed as bit-image data if the receive buffer becomes full while transmitting bit-image data. 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 with a 4-KB receive buffer. The amount of data for one line must not make the receive buffer become full.

(8) Notes on setting Memory switch 1-7 to ON

1) When using #6 pin (DSR) to reset, turn memory switch 1-7 ON.

2) When memory switch 1-7 is turned ON, the printer enters reset status when MARK level is input to #6 pin (DSR) or connector (terminal) is open.

3.12 Optional external buzzer *For specified customer only

(1) Optional external buzzer settings

The optional external buzzer (OT-BZ20) can be used by connecting it to the drawer kick connector and, under software settings, setting the "Optional external buzzer enabled/disabled" item to "Enabled".

(a) Sounding/stopping by the buzzer commands

 It is possible to sound the buzzer by setting a sound pattern and a buzzer frequency with ESC ( A.

 It is possible to stop sounding the buzzer with DLE DC4 <Function 3>.

(b) Cooperative sounding by using commands other than the buzzer commands

 Buzzer sounding is possible by autocutting commands/operations (GS V 0, GS V 65, ESC i, ESC m,

autocutting for automatic top logo printing, automatic cutting at cover close).

 Buzzer sounding is possible by the commands that generate the specified pulse (drawer kick) (ESC p, DLE

DC4 <fn = 1>).

 The sound pattern and buzzer frequency can be set with the software setting. (See 3.5.2 for how to change

the setting.)

 Buzzer sounding is possible when a paper-end is detected.

 Buzzer sounding is possible when an error occurs.

 The buzzer frequency can be set with the software setting. (See 3.5.2 for how to change the setting.)

(d) Stopping the buzzer sounding

 It is possible to stop sounding the buzzer with DLE DC4 <Function 3>.

 It is possible to stop sounding the buzzer by opening the cover. (However, if the cause for sounding remains

when the cover is closed, the buzzer will begin sounding again.)

(2) Notes for when connecting, installing, and using

1) When, in the software settings, the "Optional external buzzer enabled/disabled" item is set to "Enabled", a pulse is not output to the drawer kick connector pin, and therefore, the drawer cannot be driven.

2) When the optional external buzzer is used, it is prohibited that both the optional external buzzer and the drawer are connected at the same time by using a branched connector.

3) The optional external buzzer does not sound when the optional external buzzer is connected after the printer power is on or if the optional external buzzer is disconnected and reconnected while the printer power is on; therefore, be sure to turn on the printer with the optional external buzzer connected and do not disconnect the optional external buzzer when the printer power is on.

4) Be sure to fix the buzzer to the printer unit with the affixing tape (bundled with the optional external buzzer).

5) Do not install the optional external buzzer on the roll paper eject surface, as doing so will block paper eject.

6) Be sure to clean and dry the surface of the printer and the optional external buzzer where the affixing tape is attached before attaching the affixing tape to the printer and the optional external buzzer.

7) To prevent liquid from entering, it is recommended to install the optional external buzzer so that the volume adjustment knob is positioned sideways or downward.

8) Do not purposely put any water, oil, chemicals, or any other water-based material on the buzzer. Doing so may cause a malfunction.

3.13 Printing Using Multiple Interfaces

 Models with multiple interfaces do not fix the interface to be used, but can use all the interfaces (*1).

 You can select just one interface as the primary connection interface (*1). There are no limitations on

command functions for the primary connection interface, and priority is given to processing received data.

 Other interfaces are set as secondary connection interfaces. There are limitations on command functions for

the secondary connection interface (*2), and priority is not given to processing received data.

 The following table describes the differences between the primary connection interface and the secondary

connection interfaces.

Connection I/F Connection

priority

Primary High None None Maintained

Secondary Low None Ye s Initialized

 Set the interface you want to constantly use as the primary connection interface. Be aware that if you set

primary connection interface selection to "Auto" (the interface where data is first received), the primary connection interface may not be determined uniquely based on the order of data received from each interface.

 When the primary connection interface selection is "Auto" and the primary connection interface is not

determined because data is not being received, the interface to be printed is determined as the primary connection interface.

 The printer has an independent receive buffer for each interface, data can always be received on each interface.

 If using multiple interfaces, set the receive buffer capacity to 4 KB (initial setting) (*4).

 The printer switches the active interface in accordance with the priority, and processes the data in each receive

buffer sequentially.

 The active interface can be switched when all the following conditions are met.

 The receive buffer for the active interface has been empty (there is no unprocessed data) for the set time (*5)

or longer.

 Printing has stopped.

(*1) For interface types and how to select the primary connection interface, see "3.5.2 Software setting (2)

Customized value setting."

(*2) The following ESC/POS commands are disabled for the secondary connection interface.

DLE DC4 (fn = 2), ESC &, ESC ?, GS ( D, GS ( L <Functions 81,82,83>, GS *, GS :, GS D <Function 83>, GS ^, FS 2

(*3) If you are using ePOS-Print SDK or Epson ePOS SDK, the maintaining or initializing of print settings when

closing the connection does not affect the operations of the application.

(*4) For the method to set the receive buffer capacity, see Section 3.5.2 Software setting, (1) Memory switches.

Appendix C NOTES ON USING THE DRAWER KICK CONNECTOR *For specified

OFF time

customer only

C.1 Conditions for Using the Drawer Kick Connector

Drawer specifications differ significantly depending on the manufacturer and the model. Make sure that the specifications of the drawer used meet the following conditions when connected to the drawer kick connector. These conditions also apply to any other devices to be connected to the drawer kick connector.

Never use a drawer (or other devices) that does not meet all of the following conditions:

[Conditions]

 The load, such as a drawer kick solenoid, must be connected between pins 4 and 2 or pins 4 and 5 of the drawer

kick connector. (*1)

 When the drawer open/close signal that indicates the state of the drawer is used, a switch must be provided

between drawer kick connector pins 3 and 6. (*2)

 The resistance of the load, such as a drawer kick solenoid, must be 24 Ω or more or the input current must be 1

A or less. (*3)

 Make sure to use the drawer kick connector 4 pin (24 V power supply) for driving the drawer. Never connect

any other power supply to the drawer kick connector. (*4)

 The peak current is 1 A. See item (2) below for power status.

*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 less than 24 Ω or whose input current is more than 1 A may

cause an overcurrent and damage the connected equipment as well as the printer.

*4: Operation is not guaranteed with other power supplies.

C.2 Notes on the pulse generating command (ESC p)

When using ESC p to drive the drawer connected to the drawer kick connector, set the command parameters to meet the following conditions:

ESC p m t1 t2

Or, OFF time ≥ ON time × 4 ······ Formula C-2

ON time + OFF time

ON time

≤ 0.2 ······ Formula C-1

Figure C.1.1 shows the drive signal waveform generated when the drawer is driven according to the above

PRINT#1, CHR$(&H1B); "p"; CHR$(0); CHR$(100); CHR$(250);

GOSUB *WAIT300MS

*WAIT300MS

RETURN

conditions.

OFF

t1 × 2 ms t2 ≥ (t1 × 4) × 2 ms

Figure C.1.1 Drawer Drive Signal Waveform

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 C-1 and C-2, see C.3.

C.3 Using a drawer that does not meet the conditions in C.2 (ESC p, DLE DC4)

For ESC p

Setting the values of t1 and t2 according to the conditions in C.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)

α: processing time of other sequence α is the period from the OFF time until the next ON time when the drawer-driving is prohibited.

For DLE DC4

Since DLE DC4 sets ON time equal to OFF time, use α so that Formula C-3 is met.

Appendix D NOTES ON UPDATING THE MAINTENANCE COUNTER AND TURNING

THE PRINTER'S POWER OFF

D.1 About Updating the Maintenance Counter

 This printer has a maintenance counter with functions 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 D.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 while the power is turned on, the printer enters

the power-saving mode.

D.2 Printer Power-off Procedures

 If turning the power off without using the power switch, we recommend doing so after executing the power-off

sequence command DLE DC4 (fn = 2).

 The following is an example of the printer power off process when the printer is turned off using the DLE DC4

(fn = 2) command.

Step 1: The host computer transmits the following continuous procedure before the system is turned off:

(1) Executes GS ( D pL pH m a b (pL=3, pH =0, m =20, a =2, b =1) (2) Executes GS r n (n =1)

Step 2: The host computer waits for the paper sensor status sent from the printer in response to the GS r n

command.

Step 3: The host computer transmits DLE DC4 fn a b (fn = 2, a = 1, b = 8).

Step 4: The host computer waits for the power-off notice.

Step 5: After receiving the power-off notice, wait one second or longer, then turn off the power.

Notes:

 The power-off sequence is performed within approximately 5 seconds after DLE DC4 fn a b is sent, and then the

power-off notice is sent. After that, the printer enters power-off standby.

 If the power-off notice is not confirmed, wait for at least 5 seconds after transmitting DLE DC4 fn a b. At this

time, the printer has only performed software processing, and the power is not turned off.

 Do not reset the printer until you have confirmed the power-off notice after transmitting DLE DC4 (fn = 2).

Appendix E NOTES ON PRINTING BAR CODES AND 2-DIMENSIONAL SYMBOLS

 User must set the quiet zone, depending on the bar code standards.

 When printing PDF417 (2-dimensional symbols), it is recommended to set the height of one step of the symbol

to three to five times the width of one module. The total height of code should be approximately 5 mm {0.20"} or more.

 The recognition rate of ladder bar codes and 2-dimensional symbols may vary depending on widths of the

modules, print density, environmental temperature, type of roll paper (thermal paper), and characteristics of the reader. Therefore, user must check the recognition rate before setting the use conditions so that the restrictions of the reader are satisfied.

 Reading quality of bar codes/2-dimensional symbols in multi-tone graphics printing is not guaranteed.

 When printing ladder bar codes/2-dimensional symbols with graphics printing, instead of using the bar

codes/2-dimensional symbols print commands, set the print speed to speed level 5. The print speed level can be set with GS ( K.

Appendix F NOTES ON SCANNING THE PRINT RESULT ON THE RECEIPT

To determine whether the ability of the reader (scanner) can be satisfied by using bar codes, 2-dimensional symbols, or characters printed on receipt (roll paper), take the following points into consideration.

1) Print density The print density may vary depending on the type of roll paper or the environmental conditions.

2) Slant of the Print The printed bar code or characters may not be horizontal to the paper as shown in the figure below. They may slant in the range of ± 1.6° and the slanting direction or the angle varies during printing or each time a receipt is issued.

Figure F.1 Slant of the Print

Note: If paper other than the ones described in Section 1.6, Paper Specifications, is used or if the paper is used out

of the range described in Section 1.13, Environmental Conditions, the print density may vary or the slant of print result may become wider.

Appendix G NOTES ON USING THE ASB STATUS

(4) 0001 1100 0000 0000 0000 1111 0000 1111

When the ASB status is received following this, the actual ASB that is sent is a total of eight (8) bytes, consisting of the combined ASB (1 + 2 + 3 + 4) and the latest ASB (4).

Note: When the primary connection interface selection is set to "Auto", set ASB with the secondary connection

interface if you wish to obtain ASB with said interface.

Appendix H NOTES ON ARP (AUTOMATIC REDUCTION OF PAPER) AND

AUTOMATIC LOGO PRINTING FUNCTION

H.1 ARP: Reduction of Excessive Top Margin, Reduction of Excessive Bottom Margin, Reduction

of Line Spacing, and Reduction of Line Spacing Where Extra Line Feeds Are Included

 Paper reduction is not performed for space dot lines of graphics printing data.

H.2 ARP: Reduction of Bar Code Height

 When reducing bar code height, reading of the bar code is not guaranteed. Be sure to check reading a bar code

with a user’s bar code reader in advance.

H.3 Automatic Logo Printing Function

 The automatic bottom logo printing is a function of logo printing that works with an autocutting command and

produces good printing quality when using the GS V m n (paper feeding + paper cutting) command. When using cutting-only commands (GS V m, ESC i, or ESC m), extra line spacing above a bottom logo occurs, depending on the paper feeding command before the cutting command.

 When printing a top logo during paper feeding to the cutting position, the GS V m n (paper feeding + paper

cutting) command will produce good printing quality. When using cutting only commands, printing a logo before cutting is not performed.

Figure I.1

Figure I.2

Appendix I SETTING PAPER WIDTH

I.1 Notes

 If changing the paper width from 80 mm {3.15"} to 58 mm {2.28"}, install the included roll paper guides for 58

mm {2.28"} paper width.

 Be sure to set the paper width using software settings to align the print area. (For the setting method, see 3.5.2

(2).)

Note: After changing the paper width from 80 mm {3.15"} to 58 mm {2.28"}, while using 58 mm {2.28"}, you are

prohibited from changing the paper width again back to 80 mm {3.15"}. (If using paper with a 58 mm {2.28"} width, part of the head will rub directly against the platen without any paper, so the part of the head that rubbed against the platen may be damaged. Also, the section of the cutter blade without paper may be dulled. Therefore, printing and auto-cutting cannot be done for the expanded section of the paper width.)

I.2 Method for Installing 58 mm {2.28"} Roll Paper Guides

Step 1: Check that the printer's power is off, then open the roll paper cover.

Step 2: Align the three protrusions of the 58 mm {2.28"} width roll paper guide (marked as L SIDE) with the slits

on the Power button side of the printer, and insert them.

Figure I.3

Step 3: Align the three protrusions of the other 58 mm {2.28"} width roll paper guide (not marked as L SIDE)

with the slits on the opposite side of the printer, and insert them.

Step 4: Set the roll paper.

Step 5: Close the roll paper cover, then turn the printer power on.

Appendix J NOTES ON PRINTING AND BACKFEED

1) If top margin specification via backfeed (3.5.2 (2)) is enabled, the backfeed operation is performed before starting printing directly after the autocut. If top eject, this backfeed operation is performed after the paper in the eject port is removed.

2) If enabling the top margin specification via backfeed (3.5.2 (2)), we recommend disabling the auto top logo printing (3.5.2 (6)). Backfeeding a paper that uses top logo printing can often cause paper jams.

3) Even if top margin specification via backfeed (3.5.2 (2)) is enabled, the backfeed is not performed in the following cases.

 Backfeeding directly after autocutting of roll paper when the roll paper cover is closed

 Backfeeding during the self-test

4) When backfeeding is performed, slack in paper can cause wrinkles and friction marks. Check with the user before using. If you wish to prevent friction marks, use thermal paper that has high resistance to abrasion.

5) Perform autocutter operation after feeding paper a minimum of 20 mm.

(This is to prevent small pieces of cut paper from dropping into the autocutter and causing paper jams.)

Appendix K THAI CHARACTER PRINTING

 To print using Thai characters, you can use the Thai character 1-pass print mode or Thai character 3-pass print

mode. Select the Thai character print mode in the software settings. (See Section 3.5.2 for how to change the setting.)

Appendix L USING A POWER SUPPLY OTHER THAN THE PS-180

 If the power supply has low performance or the print duty is high, the power supply might become cut off. In

such a cause, you may be able to avoid power supply cut-offs through the combination of the power supply capacity setting, print speed setting, and number of energized head divisions setting below.

Note: However, operation with a power supply other than the PS-180 is not guaranteed.

 If the power supply capacity is set low and you perform printing with a high print duty, the print speed can be

automatically lowered to reduce the current consumed per unit hour. You can use the customized values (memory switches) to change the setting from "Power supply capacity level 3 (Default, Capacity: High; PS-180 equivalent)" to "Power supply capacity level 2" or "Power supply capacity level 1 (Capacity: Low; Adapter C equivalent)."

"Power supply capacity level 3 (Default, Capacity: High)" setting

Consumed current

"Power supply capacity level 2" setting

"Power supply capacity level 1 (Capacity: Low)" setting

Print duty

Figure L.1 Relationship between Power Supply Capacity Setting and Consumed Current (Illustration)

 Even if the print speed is set slow and you perform printing with a low print duty, you can reduce the current

consumed per unit hour. You can use the customized values (memory switches) to change the print speed setting.

 By changing the number of energized head divisions setting from 1 division (default) to 2 or 4 divisions, you can

reduce the peak current during printing. If you set the division printing to a setting other than 1 division (default), the print speed will automatically be limited. You can use the customized values (memory switches) to change the number of energized head divisions setting.

* Refer to section 3.5.2 for how to change the customized values (memory switches).

Software

Description

TM printers from native applications of

The following software is provided for application development.

S.4.1 Development Kit

Epson ePOS SDK for Android This is a development kit for controlling

smart devices. This includes libraries, manuals, and sample programs.

EPSON OPOS ADK This OCX driver can control POS peripherals using OLE technology. *1

Because controlling POS peripherals with original commands is not required on the application side, efficient system development is possible.

EPSON OPOS ADK for .NET The OPOS ADK for .NET is a POS industry standard printer driver compatible

with Microsoft POS for .NET. It allows you to develop applications that are compatible

with the UPOS (Unified POS) specification. When developing applications, use a separate development environment such as Microsoft Visual Studio .NET.

EPSON JavaPOS ADK (Windows)

JavaPOS is the standard specification which defines an architecture and device interface (API) to access various POS devices from a Java based system. Using JavaPOS standard API allows control with Java based applications of functions inherent to each device. A flexible design with Java language and JavaPOS enables many different types of computer systems, such as stand alone or network configuration, to use a same application. You can use JavaPOS to build applications and drivers independently of platforms. This allows flexible configurations using thin clients to meet the system requirements.

*1: OLE technology developed by Microsoft divides software into part blocks. The OPOS driver is presupposed

to be used with a development environment, such as Visual Basic, unlike ordinary Windows printer drivers. It is not a driver to be used for printing from commercial applications. You can acquire documents regarding

the UnifiedPOS from the following link. https://www.omg.org/retail/unified-pos.htm

S.4.2 Drivers

Software Description Operating

EPSON Advanced Printer Driver (APD)

EPSON TM Virtual Port Driver

In addition to ordinary Windows printer driver functions, this driver has controls specific to POS. The Status API (Epson original DLL) that monitors printer status and sends ESC/POS commands is also attached to this driver.

This is a serial/parallel-USB/LAN conversion driver to make an Epson TM/BA/EU printer connected via USB or LAN accessible from a POS application through a virtual serial or parallel port. It allows you to directly control devices connected via USB or LAN with ESC/POS commands without making changes in the POS application that controls devices connected via a serial or parallel interface.
