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.

Adjusting the Paper Roll Near-End Sensor
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.
Follow the steps below to adjust the roll paper near-end sensor.
1
Open the roll paper cover, and remove the roll paper.
2
Loosen the adjustment screw fastening the sensor, and then operate the knob to
align the top edge of the positioning plate with the upper or lower level.
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.

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.
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/

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)
No reduction is applied to blank dot lines that exist in a graphic data.

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.

Appendix
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

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)
