memory contains the following memory areas for the user:
• NV graphics memory
• User NV memory
• Memory switches
• R/E (Receipt Enhancement)
• Maintenance counter
NV memory can be rewritten about 100,000 times. As a guide, NV memory rewriting should be 10
times or less a day when you program applications.
CAUTION
NV Graphics Memory
Graphics, such as shop logos to be printed on receipts, can be stored. Even with a serial interface model whose
communication speed is low, high speed graphics printing is possible.
To register your graphics data, use TM-T88VII Utility or ESC/POS commands.
You can check registered graphics data using TM-T88VII Utility or by printing the data in the NV graphics
information print mode.
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.
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 "Software Settings" on page 59.
R/E (Receipt Enhancement)
You can set the graphics data, such as a shop logo, registered in the NV graphics memory to be printed on the
top of each receipt or to be printed on the bottom of each receipt just before the paper is cut.
To make the settings, use TM-T88VII Utility or ESC/POS commands.
You can check the settings using TM-T88VII Utility or by printing the settings information in the Receipt
enhancement information print mode.
24
Chapter 1 Product Overview
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 also check the head running length and number of times of autocutting with the self-test
(see "Self-test Mode" on page 71).

Simple Setup for Wireless LAN
The printer has "SimpleAP" mode that allows a device to directly connect to the printer without using an access
point. You can configure wireless LAN settings using the printer setting tool and print on the printer using the
direct connection.
• The printer acts as an access point in the SimpleAP mode and allows up to eight devices to connect
to the printer.
• Connection to a wireless LAN or wired LAN and connection using the SimpleAP mode can be made
at the same time.
• Communication between devices connected to the printer in the SimpleAP mode is impossible.
• If the printer is already connected to a wireless LAN and setting using the SimpleAP mode is
started, the wireless LAN connection is temporarily disconnected.
• If you change the passphrase, connection using SimpleAP from an Android 10 device is disabled. It
may also occur with a device running other OS. If that happens, delete the printer's SimpleAP SSID
profile in the Wi-Fi settings of the Windows, iOS, or Android device, and then connect to the printer
again.
SimpleAP is enabled by default. The printer automatically prints the information shown below when it is turned
on with the following conditions; SimpleAP enabled, not connected to a wireless LAN/wired LAN/USB device,
and wireless LAN settings have not been configured.
The printer activates SimpleAP when it is turned on for the first time, however, if you change the printer
settings using TM-T88VII Utility for Windows or EpsonNet Config, SimpleAP is disabled.
To activate SimpleAP again, start it by selecting the SimpleAP menu that is available after printing a status sheet,
or reset the network settings.

Useful Functions for Smart Devices
You can easily connect this product to the network by using the NFC tag built-in to the printer or the QR code
printed on the status sheet.
NFC Tag
Bring a smart device that supports NFC close to the NFC tag to acquire the printer information (information
for specifying the device).
Specify the target printer using the acquired information to connect to the network.
QR Code
Capture the QR code printed on the status sheet with the camera on your smart device to acquire the printer
information (information for specifying the device).
Specify the target printer using the acquired information to connect to the network.
• Programming using Epson ePOS SDK is required to use these functions. These functions are
created by combining NFC touch and QR code capturing operations and the target printer
specifications using Printer Easy Select API.
See the "Epson ePOS SDK for Android/iOS User's Manual" and the Epson ePOS SDK sample
program for more details. The sample program also contains a sample implementation method for
reading an NFC tag and capturing a QR code.
• You can try a demo of these functions by using Epson TM Utility for iOS/Android.

Chapter 1 Product Overview
Printing Using Multiple Interfaces
In printers with multiple interfaces, you can use all interfaces without any limitations on which interface is to be
used. You can use this function to temporarily connect a smart device to a nearby printer and print.
The printer provides each interface with an independent receive buffer and switches the active interface
depending on the priority, while handling data in each receive buffer.
You can set one interface for the main connection. Data received from the main connection interface is handled
with the highest priority.
By default, the interface that receives the first data transfer is set as the main connection interface; however, you
can select the main connection interface in advance.
In the status where all receive buffers are empty for more than the set time (1 second by default), interface
switching is enabled. The interface that receives the data in this status becomes active.
You cannot use wired and wireless LANs at the same time. When a LAN cable is connected, wireless
LAN is disabled.
You can select the main connection interface and set the time to enable interface switching from the
software settings. For details on software settings, see "Software Settings" on page 59.

Below are two situations where a roll paper NE 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.
• 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.
• To let the NE sensor detect remaining amount of paper accurately, it is recommended to use a roll
paper with a core inner diameter of 12 mm {0.47"} and outer diameter of 18 mm {0.71"}.
• An outer diameter of a paper roll that is detected as near-end varies by usage environment, and/or
paper specifications. Please check operation of the NE sensor by yourself.
Follow the steps below to adjust the roll paper near-end sensor.
Open the roll paper cover, and remove the roll paper.

Print Density
Monochrome
Selectable from 70 to 130% (5% increment)
Default setting: 100%
Depending on the paper type, it is recommended to set the print density as shown in the table below for the best
print quality.
Original Paper typeDensityPrint speed
AP50KS-ND100%17 (500 mm/sec)
KT55FA, AP45KS-ND100%16 (450 mm/sec)
KT48FA, KT55PF100%15 (400 mm/sec)
KT48PF, P5047(55), P5047(46)105%15 (400 mm/sec)
• When the print density level is increased, print speed may be reduced. When printing at a
density of 115% or more and below a room temperature of 15°C, the speed drops to less than
200 mm/sec.
• When setting the print speed to level 17, use customized values to set the print density.
Multi-Tone
Selectable from 70 to 130% (5% increment)
Default setting: 100%
Print Speed
• High Speed (500 mm/s)
• Standard Speed (450 mm/s) (default setting)
• Middle Speed (350 mm/s)
*Default setting: Varies by country/region where the printer is purchased
• The print speed is restricted according to the Number of head energizing parts setting.
The maximum 500 mm/s is possible with the One-part energizing (default) option.
The Number of head energizing parts setting can be changed using ESC/POS commands. ("ESC/
POS" on
• The maximum
page 85)
printing speed when using 58 mm is 450 mm/s.

• When setting the print speed to [High Speed], set the print density using Customized Value
Setting.
• Depending on print conditions, such as print duty, print head temperature, and data
transmission speed, print speed is automatically adjusted, which may cause white lines due to
intermittent print (the motor sometimes stops). To avoid this, keep the print speed constant by
setting it lower.
• By using a setting tool such as TM-T88VII Utility, the print speed can be selected from 17 levels
(from the slowest level 1 to the fastest level 17). (Default setting: level 16)

∗ Immediately after auto cutting while the cover is closed.
∗ While the self-test is in progress.
• If setting a top margin of 5 mm {0.2"} or less, confirm that no errors occur in your environment of
usage. Usage in a hot and humid environment or usage of paper that curls easily may increase
the risk of paper jams.
• When implementing a backfeed, rubbing smears may occur due to slack in the paper. We
recommend using thermal paper with high rub resistance.

Development Kits
SoftwareDescription
EPSON OPOS ADKThis 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 .NETThe 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)
Epson ePOS SDKThis is a developer kit to control applications, native applications for smart devices,
for Android
for iOS
for JavaScript
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.
and printers. This includes libraries, manuals, and sample programs.
*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.
