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 use the
counter information for periodical checks or part replacement.
• You can also check the print head running length and number of times of autocutting with the
self-test (see
• The maintenance counter value is normally saved in the NV memory every 2 minutes (maximum
of 4 minutes). However, it is not automatically saved when the product is in the power-saving
mode or when the power is turned off without using the power switch.
"Self-test Mode" on page 54).

Chapter 1 Product Overview
Simple Setup for Wireless LAN
This printer comes with a mode (SimpleAP) that allows printers to connect with a smart device or a computer
without requiring a wireless access point. This allows you to easily setup a wireless LAN for the printer by using
a printer settings tool (TM-T82III Utility, Epson TM Utility for iOS/Android, or EpsonNet Config) even
without a network environment such as access points.
SimpleAP mode is enabled by default when shipping from the factory. When SimpleAP mode is enabled and
the printer is turned on, the following information is printed automatically.

Although operations are performed in SimpleAP mode during the initial startup, operations switch to standard
mode (infrastructure mode) when changing settings in Epson TM-T82III Utility or EpsonNet Config. After
switching, operations continue in standard mode. If you want to make settings in SimpleAP mode again,

Below are two situations where a roll paper near-end sensor adjustment is required.
• To adjust the detection position to suit the diameter of the roll paper core used.
• To adjust the detection position of remaining amount of paper.
• The roll paper near-end detection function can be used only when this product is installed
horizontally.
• Be sure to disable the near-end detection when the product is installed vertically or is wallmounted. Failure to do so may lead to erroneous detection.
• Since roll paper cores vary slightly in shape, depending on paper roll design and manufacturing
tolerances, it is impossible to detect the remaining paper exactly.
• Use roll paper with a core inner diameter of 12 mm {0.47"} and outer diameter of 18 mm {0.71"}
so that the near-end sensor can detect the remaining paper as accurately as possible.
• To use the near-end detection, it must be enabled using the memory switches. See "Software
Setting Mode" on page 55
Follow the steps below to adjust the roll paper near-end sensor.

Software
The following software is provided for application development.
Development Kits
Software Description
EPSON OPOS ADK This OCX driver can control POS peripherals using OLE technology.* 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/Linux) 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.
Epson ePOS SDK This is a developer kit to control applications, native applications for smart
for Android
for iOS
for JavaScript
* 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.

• Paper must not be pasted to the roll paper spool.
• For the best print quality for each paper type, it is recommended to set the print density. (See
"Software Settings" on page 42.)
• Use of thermal paper with a pre-printed recording surface should be avoided. Using it can cause
the thermal head to stick to the thermal paper surface during printing, and cause printing
failure and other problems. The pre-printing also can result in reduced print density. Using
thermal paper with a pre-printed recording surface, pre-printing should be done in accordance
with the conditions (ink type, printing and other conditions) recommended by the paper
manufacturer, and the thermal paper should be checked to ensure that there is no faulty
printing, loss of print density, or other problems.

• The values above may vary slightly as a result of paper slack or variations in the paper. Take this
into account when setting the cutting position of the autocutter.
• When removing cut paper, the remaining roll paper is pulled at the uncut section and the pitch
of the next print may be reduced. When printing after cutting paper for prints with no pitch
reduction, feed the paper about 1 mm {16/406 inches} before printing.
• When leaving paper loaded for an extended period of time, make sure you feed about 40 mm of
paper. This can prevent paper from wrinkling and causing prints to be too light.

Reverse Mode
The transfer of status data from the printer to the host proceeds in the nibble or byte mode.
This mode allows data transfer from an asynchronous printer under the control of the host. Data transfers in
the nibble mode are made via the existing control lines in units of four bits (a nibble). In the byte mode, data
transfer proceeds by making the 8-bit data lines bidirectional. Both modes fail to proceed concurrently in the
compatibility mode, thereby causing half-duplex transmission.

Notes on Using the Wi-Fi Model
• Keep the printer away from the devices, such as kitchen microwaves, that may cause radio wave interference.
• Use channels that are away from the frequency bands that may cause radio wave interference.
• Place shields between the printer and the devices that may cause radio wave interference.
• Select either 2.4 GHz or 5 GHz, whichever is free from radio wave interference.
• In auto channel setting for the access point, do not select a channel in which the devices may cause radio
wave interference.
