Chapter 1 Product Overview
NV Memory (Non-Volatile Memory)
The printer's NV memory stores data even after the printer power is turned off. NV memory
contains the following memory areas for the user:
• NV graphics memory
• User NV memory
• Memory switches
• R/E (Receipt Enhancement)
• User-defined page
• Maintenance counter
NV memory can be rewritten about 100,000 times. As a guide, NV memory rewriting should
be used 10 times or less a day when you program applications.
NV Graphics Memory
Graphics, such as shop logos to be printed on receipts, can be registered.
Use the TM-T20 Utility to register graphics. You can also use the TM-T20 Utility or the NV
graphics information print mode to print and confirm the registered graphics.
• For information about the TM-T20 Utility, see the TM-T20 Utility User’s Manual.
• For information about how to use the NV graphics information print mode, see "NV
Graphics Information Print Mode" on page 62.
User NV Memory
You can store and read text data for multiple purposes, such as for storing a note including
customizing or maintenance information of the printer.
Use ESC/POS commands to store and read the text data.
For information about ESC/POS commands, see the ESC/POS Application Programming
Guide.
Memory Switches
With the memory switches, which are software switches for the printer, you can configure
various settings of the printer. For information about the memory switch, see "Setting the
Memory Switches/Receipt Enhancement" on page 39.
19
1
R/E (Receipt Enhancement)
Graphics, such as shop logos can be printed on top or bottom of receipts by setting R/E (Receipt
Enhancement). For information about R/E, see "Setting the Memory Switches/Receipt
Enhancement" on page 39.
User-defined Page
You can store character data in the user-defined page (character code table: page 255) so that you
can also print characters not resident in the printer.
Maintenance Counter
With this function, printer information, such as the number of lines printed, the number of
autocuts, and printer operation time after the printer starts working, is automatically stored in
NV memory. You can read the information with the Status API of the APD or OPOS ADK to use
it for periodical checks or part replacement.
You can also check the head running length and number of times of autocutting with the
self-test (see "Self-test Mode" on page 59.) and the TM-T20 Utility.

• Because some parts of the print head and the autocutter contact the platen and they
may become worn out, once you change the paper width from 80 to 58 mm and use the
printer, you cannot change it back to 80 mm.
Printing speed may be slower, depending on the such items as the data transmission
speed.

When the optional buzzer unit (model: OT-BZ20) is connected to the drawer kick-out connector
of the printer, you can set the printer so that it beeps when you send commands, when an error
occurs, and when the printer does specific operations such as autocutting. Settings for sound
patterns and frequency depending on the occasions the buzzer beeps are also available.
You need to set the memory switches for buzzer enable/disable setting, sound pattern setting,
and frequency setting. For information about the memory switches, see "Setting the Memory
Switches/Receipt Enhancement" on page 39.

Connecting the Drawer Kick-out Cable
WARNING
• Specifications of drawers differ depending on makers or models. When you use a
drawer other than specified, make sure its specification meets the following
conditions.
Otherwise, devices may be damaged.
∗ 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.
∗ When the drawer open/close signal is used, a switch must be provided between
drawer kick-out connector pins 3 and 6.
∗ 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.
∗ Be sure to use the 24V power output on drawer-kick out connector pin 4 for driving the
equipment.
• Use a shield cable for the drawer connector cable.
• Two driver transistors cannot be energized simultaneously.
• Leave intervals longer than 4 times the drawer driving pulse when sending it
continuously.
• Do not insert a telephone line into the drawer kick-out connector.
Doing so may damage the telephone line or printer.

Chapter 3 Application Development Information
Application Development Information
This chapter describes how to control the printer and gives information useful for printer
application development.
How to Control the Printer
Use a driver or ESC/POS commands to control the printer.
Selecting a Driver
Choose one of the drivers listed in "Printer Drivers" on page 56, depending on the application
operating environment. You cannot control a single printer with more than one driver.
For information about the driver operating environment, see the installation manual for each
driver.
When you newly develop an application
• Use APD if you want to print TrueType fonts or print many graphics.
• OPOS ADK is recommended for system extensibility. An OPOS driver is provided for various
peripherals and it is a POS industry standard now. It enables POS system efficiency, reduction
of development cost, and effective use of application assets.
You can use all functions, including ones not supported by OPOS ADK or APD, by using
ESC/POS commands through your driver. Use the DIRECT I/O function of OPOS ADK, the
control A command of APD, or Status API to send ESC/POS commands from each driver.
(See "ESC/POS command functions" on page 50.)
49
3
ESC/POS Commands
ESC/POS is the Epson original printer command system. With ESC/POS commands, you can
directly control all the TM printer functions, but detailed knowledge of printer specifications or
combination of commands is required, compared to using a driver.
To use ESC/POS commands, you need to agree to a nondisclosure contract first and obtain the
ESC/POS Application Programming Guide. Ask your dealer for details.
The ESC/POS command functions are listed below. See the ESC/POS Application Programming
Guide for more details.

Printer Drivers
Software
EPSON Advanced Printer Driver (APD):
• APD Install Manual
In addition to ordinary Windows driver functions, this
driver has controls specific to POS, such as controls for
paper cut, a cash drawer, and customer display. The
Status API (Epson original DLL) that monitors printer
status and sends ESC/POS commands is also
attached to this driver.
• APD TM/BA/EU Printer Manual
EPSON OPOS ADK:
• OPOS Installation Manual
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.
• User’s Manual
EPSON OPOS ADK for .NET:
• OPOS ADK for .NET Installation Guide
OPOS ADK for .NET allows you to develop
applications that are compatible with Microsoft POS
for .NET.
• User's Reference (SetupPOS)
When developing applications, use a separate
development environment such as Microsoft Visual
Studio .NET.
• UnifiedPOS Retail Peripheral Architecture*2
EPSON JavaPOS ADK:
JavaPOS ADK Installation Guide
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.

Cleaning the Printer
Cleaning the Printer Case
Be sure to turn off the printer, and wipe the dirt off the printer case with a dry cloth or a damp
cloth.
Never clean the product with alcohol, benzine, thinner, or other such solvents.
Doing so may damage or break the parts made of plastic and rubber.
CAUTION
Cleaning the Thermal Head/Platen Roller
Epson recommends cleaning the thermal head periodically (generally every 3 months) to
maintain receipt print quality.
Depending on the roll paper used, paper dust may stick to the platen roller and the paper may
not be fed correctly. To remove the paper dust, clean the platen roller.
Turn off the printer, open the roll paper cover, and clean the thermal elements of the thermal
head/platen roller with a cotton swab moistened with an alcohol solvent (ethanol or IPA).
CAUTION
• After printing, the thermal head can be very hot. Do not touch it and let it cool
before you clean it.

Status transmission from printer with USB interface
In order to ensure that there is no lack of status data, it is necessary to periodically retrieve status
data at the host computer.
However, 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.
