28
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.

Setting the DIP Switches
On this printer, you can make various settings with DIP switches.
The DIP switches are already set for the current interfaces. Change the setting if necessary.
Functions of the DIP switches differ depending on the interface.
Setting Procedure
Follow the steps below to change the DIP switch settings.
1Make sure the printer is turned off.
2Unscrew the screw to remove the DIP switch cover from the base of the printer.
CAUTION
•Before you remove the DIP switch cover, turn off the printer and disconnect all cables.
Otherwise, a short-circuit may cause the printer to malfunction.
•If you open the DIP switch cover, be sure to close the cover and tighten the screw after
adjusting the DIP switch.
Using this product with the cover open may cause fire or electric shock.
•DIP switch settings are enabled only when the power is turned on or the printer is reset via the
interface. If the settings are changed after that, the functions will not change.
•Do not change switches that are fixed to ON or OFF. Otherwise, the printer may not operate
normally.

Printing and Cutting Positions
•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 30 mm
of paper. This can prevent paper from wrinkling and causing prints to be too light.

•Paper must not be pasted to the roll paper spool.
•The remaining amount of the roll paper when a roll paper near-end is detected differs
depending on the spool type.
•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.

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 printer may cause radio
wave interference.
Notes on Wi-Fi connection
Because not all the combinations of the printer and Wireless LAN units have been checked for operation, the
operation of the printer in combination with all the Wireless LAN units is not guaranteed. Be sure to carry out
evaluation of the operation before use.
Notes on use
•When you initialize or change the printer settings, the printer is reset to reflect the settings. It may take about
1 minute depending on the network settings or environment. Also, your application may indicate power off
during the time waiting for reset. In that case, wait for about 1 minute, and then reconnect to the printer.
•Where Wi-Fi communication is in heavy traffic, your application may falsely recognize that the
communication is disconnected and indicate power off due to response delay. In that case, disable Power
Save to improve the trouble.

IEEE 1284 Parallel Interface
Modes
The IEEE 1284 parallel interface supports the following two modes.
Compatibility Mode
Compatibility mode allows data transmission from host to printer only: Centronics-compatible.
Specification
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.
Mode Communication direction Other information
Compatibility mode Host → Printer communication Centronics-compliant
Reverse mode Printer → Host communication Assumes a data transfer from an asynchronous
printer
Data transmission 8-bit parallel
Synchronization Externally supplied STROBE signals
Handshaking ACK and BUSY signals

Bluetooth Low Energy Technology Advertising
Introduction
When you connect the BT820 from Lairedtec to the USB A connector on the TM-T88VII and turn it on, the
Bluetooth low energy technology Advertising Packet is transmitted. By default, the TM-T88VII transmits the
packet according to the iBeacon Format from Apple. You can also change the data that is transmitted by
following the steps in "Changing the Bluetooth Low Energy Technology Advertising Packet" on page 130.
Glossary:
Dongle specifications
Manufacturer: Laird Tech
Model name: BT-820
For setting methods and settings, see the TM-T88VII Utility User's Manual.
Procedure
When turning on the TM-T88VII, the Bluetooth adapter connected to the USB Type A connector is enabled.
If you install the Bluetooth adapter after turning on the printer, this is not enabled.
Bluetooth Low Energy Technology Advertising Packet Format
In the TM-T88VII, the iBeacon format is used by default for the Bluetooth low energy technology Advertising
Packet.
The UUID for the T88VI is "fac1ba2f-61a2-4d83-9a8c-60087c232569".
The user can edit the following specifications in the iBeacon format: UUID, Major number, Minor number, and
Measured Power.

Appendix
Table 1 iBeacon Packet Format
Changing the Bluetooth Low Energy Technology Advertising Packet
The TM-T88VII can acquire a configuration script from the printer.
You can also change settings by transmitting the configuration script to the printer.
The configuration script only supports UTF-8 encoding.
The iBeacon Format is defined in the configuration script by default for the TM-T88VII.
You can change this Packet Format to support Eddystone-UID or Eddystone-URL.
However, the T88VI only supports single Advertising Data Packets.
You can change the settings using either of the following two methods.
•Changing settings using the Epson TM-T88VII Utility for Windows (see the TM-T88VII Utility User's Man-
ual for details)
•Changing settings using an HTTP Request
The method of changing settings via an HTTP Request is explained below.
