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.

Functions

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 type Density Print speed

AP50KS-ND 100% 17 (500 mm/sec)

KT55FA, AP45KS-ND 100% 16 (450 mm/sec)

KT48FA, KT55PF 100% 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)

• 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.
