Chapter 1 Product Overview

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

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.

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).

• T

he 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 powersaving mode or when it is turned off without the use of the power switch.

SSID : DIR ECT-T M-T88V II- XXXXXXXXXX

Serial number of the printer

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.

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.

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.
