NV Memory

The printer's NV memory (Non-Volatile 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)

• Maintenance counter

• Web contents

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-T88VI Utility or ESC/POS commands.

You can check registered graphics data using TM-T88VI 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 56.

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-T88VI Utility or ESC/POS commands.

You can check the settings using TM-T88VI Utility or by printing the settings information in the Receipt enhancement information print mode.

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 67).

• The maintenance counter values are automatically saved in the NV memory usually every two minutes (up to four minutes). However, the values are not saved when the printer is in power-saving mode or when it is turned off without the use of the power switch.

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 (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.

SimpleAP Start

SSID Encryption Type Passphrase

IP Address MAC Address

: EPSON_Printer : WPA-2-PSK : 12345678

: 192.168.192.168 : xx-xx-xx-xx-xx-xx

Although operations are performed in SimpleAP mode during the initial startup, operations switch to standard mode (infrastructure mode) when changing settings in Epson TM-T88VI Utility for Windows or EpsonNet Config. After switching, operations continue in standard mode. If you want to make settings in SimpleAP mode again, initialize the communication settings. (see "Resetting the Interface Settings" on page 77

Chapter 1 Product Overview

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.

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.

• When not using Bluetooth, set the Bluetooth security level to Middle or High in order to prevent third parties from unauthorized pairing. You can change the security level with Epson TM Utility, TM-T88VI Utility, or the Interface Setup mode.

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 56.

Flow of Setup

This chapter consists of the following sections along with the setup flow of the product and peripherals.

Chapter 2 Setup

Installing the Printer

You can install this printer horizontally. With an optional hanging bracket (WH-10), you can also attach the printer to a wall.

Important Notes on Horizontal Installation

• The printer must be installed horizontally on a flat surface (not tilted).

• Do not place the printer in dusty locations.

• Do not catch cables or place foreign matter under the printer.

Important Notes on Wall Hanging

You need to perform the following tasks to install the printer on a wall. For more details, see the installation manual for the optional wall hanging bracket (WH-10).

• Installing the roll-paper stoppers

• Changing the location of the roll paper near-end sensor

• Attaching the connector cover

• Attaching the wall hanging bracket (WH-10)

For the other notes, see the installation manual for the optional wall hanging bracket (WH-10).

• Be sure to attach the connector cover when you install the printer on a wall using the wall hanging bracket.

• When installing on a wall using a wall mounting bracket, the status of the wireless signal for the wireless LAN unit may decline. In this situation, use an extension cable.
