"Changing the Paper Width" on page 27.)
Once you change the paper width from 80 mm to 58 mm, you cannot change it back to
80 mm.
The print density can be set with DIP switches (2-3/2-4) or the customized value. (See
"Selecting the Print Density (DIP Switches 2-3/2-4)" on page 62.) The default setting of the
customized value is “Depends on the DIP switch settings.” If the customized value is
changed, the value set with the customized value is enabled.
First change the print density, and then configure the Multi-tone print density.
If you set the density too high, the contrast becomes lower. Select the density level
checking the overall tone balance of your image.

Chapter 6 Replacement of the TM-T88IV
83
6
Replacement of the TM-T88IV
The TM-T88V is designed so that it can smoothly replace the TM-T88IV. This chapter describes
precautions for the replacement.
Compatibility
Printing
The printing and character specifications are the same as those of the TM-T88IV. Without special
configurations, the TM-T88V prints the same results as the TM-T88IV prints.
Print Density
The print density of the TM-T88V can be set with DIP switches (2-3/2-4) as can the TM-T88IV.
Set the density the same as for the TM-T88IV to print in the same print density.
Two-Color Printing
You cannot use the paper for two-color printing (P320RB/P320BB) with the TM-T88V, which you
can use with the TM-T88IV.
Number of Head Energizing Parts
For the TM-T88V, the default setting of the number of head energizing parts is “One-part
energizing.” You can change the setting with the customized value (See "Setting the Memory
Switches (Customized Value)" on page 63.); however it does not usually need to be changed.
The print density can be set also with a customized value. The default setting of the
customized value is “Depends on the DIP switch settings.” If the customized value is
changed, the value set with the customized value is enabled. (See "Setting the Memory
Switches (Customized Value)" on page 63.)
TM-T88V TM-T88IV
Number of head energizing part
One-part energizing
Two-part energizing

Two-part energizing
Four-part energizing
Auto energizing
84
Printable Area (for 80 mm Width Paper)
The printable area (left/right margins, print start position from the autocutting position, print
start position from the manual cutting position) of the TM-T88V is the same as that of the
TM-T88IV.
Cutting Method
The TM-T88V uses the partial cutting method (cutting with one point in left edge left uncut) as
does the TM-T88IV.
Manual Paper Feed
Manual paper feed is not possible with the TM-T88V while it is possible with the TM-T88IV after
printing pauses.
Receive Buffer
You can set the receive buffer of the TM-T88V to 4KB or 45 bytes with DIP switch 1-2 as with the
TM-T88IV. The buffer full condition and buffer full release condition of the TM-T88V are the
same as those of the TM-T88IV.
Memory Capacity
The sizes of the download buffer and NV graphics data of the TM-T88V are the same as those of
the TM-T88IV.
Electrical Characteristics
The operating voltage of the TM-T88V is DC24 ± 7%, the same as the TM-T88IV. The current
consumption differs, depending on the print duty.
The TM-T88V does not have a low power consumption mode, which the TM-T88IV has, so
you cannot set DIP switches 2-3 and 2-4 to on. Use the newly added low power load mode
instead.
Chapter 6 Replacement of the TM-T88IV
85
6
DIP Switches
The functional assignments of DIP switches are the same as those of the TM-T88IV except for
DIP switches 2-3 and 2-4.
Since the TM-T88V does not have a low power consumption mode, do not set DIP switches 2-3
and 2-4 both to ON.
Printer Status
The TM-T88V goes to the same status under the same conditions as the TM-T88IV. You can
replace the TM-T88V with the TM-T88IV without modifying applications.
Logo Registration
The TM-T88V can register logos in the NV memory (NVRAM) with the TM-T88V Utility, while
the TM-T88IV can register logos with the TM Flash LOGO Setup Utility for NVRAM (TM-Flogo).
Driver Compatibility
You can operate the TM-T88V with a driver for the TM-T88IV or the TM-T88III.
Advanced Printer Driver
When the TM-T88IV was controlled by APD Ver. 4.00 ~ 4.04, you need to change the TM-T88V
printer model name to “TM-T88IV” using the customized value. (See "Setting the Memory
Switches (Customized Value)" on page 63.)
When the TM-T88IV was controlled by an APD other than Ver. 4.00 ~ 4.04, you can replace it
with the TM-T88V without modifying the APD.
OPOS ADK
If the TM-T88IV was controlled by an OPOS ADK, you can replace it with the TM-T88V without
modifying the OPOS ADK.
For detailed information about the TM-T88V Utility, see the TM-T88V Utility User’s Manual.
You cannot operate the TM-T88IV with a driver for the TM-T88V.
86
USB Low Power Consumption Mode
With the TM-T88V, you can enable the USB low power consumption mode with DIP Switch 1-8,
just as you can with the TM-T88IV. (See "For Ethernet/Wireless LAN/USB Interface" on page
60.)
Maintenance Counter
The TM-T88V has a maintenance counter just as the TM-T88IV has.
Buzzer
TM-T88V is available with a built-in buzzer or without the buzzer. Even if you purchase the one
without the buzzer, you can attach an optional external buzzer. You can beep the buzzer with the
pulse signal using a command. (See "Setting the Built-in Buzzer (for Model with a Built-in
Buzzer)" on page 42, "Connecting the Optional External Buzzer" on page 43.)
Power Supply Box
The optional power supply box (OT-BX88V) is available to be attached under the TM-T88V to
hold the power unit, just as the OT-BX88 has been available for the TM-T88IV.
For detailed information about ESC/POS commands, see the ESC/POS Application
Programming Guide.

cannot receive data.
When DTR/DSR control is selected, the printer
transmits data after confirming this signal (except if
transmitted using some ESC/POS commands).
When XON/XOFF control is selected, the printer does
not check this signal.
Changing DIP switch 2-7 lets this signal be used as a
printer reset signal.
When you use this signal as the printer’s reset signal,
the printer is reset when the signal remains MARK for
a pulse width of 1 ms or more.

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.

In order to ensure that there is no lack of status data, it is necessary to periodically retrieve status
data at the host computer.
Unlike RS 232C transmission, it cannot spontaneously interrupt data transmission to the host
computer.
The printer has a 128-byte status data buffer. Statuses that exceed the buffer capacity are
