With the “memory switch (customized value),” which is a software switch of this printer, you
can set:
•Print density
•Print speed
•Number of head energizing parts
•Single-color printing/two-color printing
• Black-color density in two-color printing
•Thai character printing mode

Selectable from levels 1 to 9 (low ∼ high). (Initial setting: level 9)
Depending on print conditions such as print duty, print head temperature, or 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, or set the transmission speed higher in case of the serial
interface. (See "Transmission speed (DIP switch 1-7/1-8)" on page 38.)

Selecting the number of head energizing parts
•One-part energizing
•Two-part energizing
•Four-part energizing
•Auto energizing (Initial setting)
• Usually, the number of head energizing parts does not need to be changed.
• The selection is effective only when single-color printing is selected. When two-color
printing is selected, the thermal head energization setting is fixed to two-part energizing.
• When auto energizing is selected, the printer usually prints in one-part energizing, but it
automatically shifts to two-part energizing if print duty is high.
• The print speed is controlled depending on the number of the head energization. The
maximum print speed (200 mm/s {7.87"/s}) can be performed only when one-part
energizing or auto-energizing is selected.
Selecting black-color density in two-color printing

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.
• 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.
• Use roll paper with a core inner diameter of 12 mm {0.47"} and outer diameter of 18 mm
{0.71"} so that the NE sensor can detect the remaining paper as accurately as possible.
Follow the steps below to adjust the roll paper near-end detector.
Open the roll paper cover, and remove the roll paper.

Chapter 3 Application Development Information
Application Development Information
This chapter describes how to control the printer and gives informationuseful for printer
application development.
How to Control the Printer
Use a driver or ESC/POS commands to control the printer.
Selecting a Driver
Choose one of the drivers, Advanced Printer Driver (APD) or OPOS ADK, depending on the
application operating environment. You cannot control the same printer with both of the drivers.
For information aboutthe driver operating environment, see the installation manual for each
driver.
When you newly develop an application
•Use APD if you want to print True Type fonts or print much graphics.
•OPOS ADK is recommended for system extensibility. A n OPOS driver is provided for various
peripherals and itis a POS industry standard now. It enables efficient POS system
establishment, reduction of development cost
, and effective use of application asset.
When APD is used for your existing application
Use APD.
When OPOS ADK is used for your existing application
Use OPOS ADK.
You can use all functions including ones not supported by OPOS ADK or APD by using a
driver with ESC/POS command. Use the DIRECT I/O function of OPOS ADK, the control A
command of APD, or Status API to send ESC/POS command from each driver. (See
"ESC/POS command functions" on page 60.)

59
ESC/POS Command
ESC/POS is the Epson original printer command system. With ESC/POS commands, you can
directly control all the TM printer functions, but detailed knowledge of printer specifications or
combination of commands is required compared to using a driver.
To use ESC/POS commands, you need to make a nondisclosure cont
ract first and get the
ESC/POS Application Programing Guide. Ask your dealer for details.
The ESC/POS command functions are listed as follows. See the ESC/POS Application
Programing Guide for more details.

Chapter 5 Replacement of the TM-T88III
Replacement of the TM-T88III
The TM-T88IV is designed so that it can smoothly replace the TM-T88III. This chapter describes
precautions for the replacement.
Compatibility
Printing
The printing and character specifications are the same as those of the TM-T88III except some
character font designs. Without special configurations, the TM-T88IV prints the same results as
the TM-T88III prints.
Font designs
The following font designs of the TM-T88IV have changed from those of the TM-T88III.
•Font A: 2, 3, 4, 5, 6, 7, 9
•Font B: 2, 6, 9
Print Density
The print density of the TM-T88IV can be set with DIP switches (2-3/2-4) as can the TM-T88III.
Set the density the same as for the TM-T88III to printinthe same print density.
The print density can be set also to a customized value. The initial 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" on
page 45.)
Print Speed
The TM-T88IV has speeded its printing up to 200 mm/s at maximum. (TM-T88III: 150 mm/s)
Depending on print conditions such as print duty, print head temperature, or 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 (See "Setting the Memory Switches" on page 45.), or set the
transmission speed higher in case of the serial interface. (See "Transmission speed (DIP
switch 1-7/1-8)" on page 38.)

Printable Area
The printable area (left/right margins, print start position from the autocutting position, print
start position from the manual cutting position) of the TM-T88IV is the same as that of the
TM-T88III.
Cutting Method
The TM-T88IV uses the partial cutting method (cutting with one point in left edge left uncut) as
does the TM-T88III.
Receive Buffer
Yo u can set the receive buffer of the TM-T88IV to 4KB or 45 bytes with DIP switch 1-2 as with the
TM-T88III. The buffer full condition and buffer full release condition of the TM-T88IV are the
same as those of the TM-T88III.
Memory Capacity
The sizes of the download buffer and NV graphics data of the TM-T88IV are the same as those of
the TM-T88III. The TM-T88IV does not have the NV user memory.
76
Chapter 5 Replacement of the TM-T88III

The functional assignments of DIP switches are the same as those of the TM-T88III. With the
same settings as for the TM-T88III, the same functions are enabled for the TM-T88IV.
Printer Status
The TM-T88IV goes to the same status under the same conditions as the TM-T88III. You can
replace the TM-T88IV with the TM-T88III without modifying applications.
Hexadecimal Dumping
Command operation during hexadecimal dumping
During hexadecimal dumping, most commands do not function.
• TM-T88IV: Only DLE EOT functions.
• TM-T88III: Only DLE EOT, DLE ENQ, and DLE DC4 function.
For detailed information about ESC/POS commands, see the ESC/POS Application
Programing Guide.
Ending hexadecimal dumping
After the hexadecimal dumping, the TM-T88IV performs autocutting (partial cut), butthe
TM-T88III does not.
