3.4 Printable Barcode Type
The TM-T88IV allows the following barcode types.
• Code 128
•
Code 128 Parsed
• Code 93
• Codabar
• ITF
• Code 39
• JAN 13 (EAN 13)
• JAN 8 (EAN 8)

• QRCODE
3.5 Power Condition Reports
The TM-T88IV supports Power Condition Reports as follows.
Powered on reporting: Supported
Powered off reporting: Unsupported
3.6 Synchronous Processing
The TM-T88IV uses Process ID to determine output completion.
Use of the Process ID allows multiple print commands to be queued to the printer
simultaneously. For this reason, Asynchronous output (AsyncMode =
TRUE)
gives a performance improvement.

Printing Position O
O: Supported
X: Unsupported
When the left margin setting function is supported, it is possible to specify the
horizontal printing position of the bitmap or barcode by dots unit.
When the printing position settings are supported, it is possible to specify the
horizontal printing position of the text, bitmap, or the barcode to the left, center, or
the right side of the paper.
3.8 Electronic Logo Function (NVRAM)
The TM-T88IV models feature an electronic logo function (NVRAM).
To use
NVRAM, start up TMFlogo utility from “Device Specific Settings” of SetupPOS
utility, and register image files (BMP style) with NVRAM in advance.
For the details of the registration, please refer to the “Help” of “TMFlogo utility”
and/or “EPSON OPOS ADK MANUAL User’s Manual TMFlogo Utility”.
To print image files registered with NVRAM, please use the either of the following
DirectIO:
PTR_DI_FLASH_BITMAP
PTR_DI_FLASH_BITMAP2.
Please refer to the corresponding part of the Section 4 of “EPSON OPOS ADK
MANUAL APPLICATION DEVELOPMENT GUIDE POSPrinter (TM Series)” for
detail. The available NVRAM sizes are as follows:
TM-T88IV : 262144 bytes

3.9 Printable bitmap types and sizes
The TM-T88IV supports the following bitmap commands. For the detail, please
refer to the corresponding part of the Section 3 of “EPSON OPOS ADK MANUAL
APPLICATION DEVELOPMENT GUIDE POSPrinter (TM Series)”. The allowance
ranges for bitmaps are as follows.
Allowance range
Bitmap command type
X (dot) y (dot) xy
Download bitmap 1~2040 1~384 <= 98304
Raster bitmap 1~2048 1~1023
One-line bitmap No setting range
3.10 Color Bitmap Printing
The TM-T88IV models support color bitmap printing.
If a 16-color or a 256-color bitmap file is supplied, the image may be printed using
2 colors. If the original file is a 2-color bitmap, it will be printed in monochrome.
The halftone method may be set using the “Device Specific Settings” dialog box.
To
print
an image using 2 colors, 2-color thermal paper must be selected in the
“Device Specific Settings” dialog box and 2-color thermal receipt paper must be
supplied in the printer.

3.12 Automatic Recovery Function
The TM-T88IV models feature a function for automatic recovery when the power
is turned on again after an interruption of power. Recovery processing is
performed automatically when the printer’s
power is turned on again after an
interruption. The recovery processing restores the printer to the condition it was in
before the power was turned off.
3.13 Output without Flow Control on the USB/Ethernet Interfaces
The TM-T88IV supports outpu
tting without flow control on the USB/Ethernet

Section 4. Warnings
This section describes precautions in use of TM-T88IV.
z When using the built-in buzzer model of TM-T88IV and TM-T88IVM with network
connection, always use a UB-E02 or UB-R02 interface board. If a device is
connected via an other interface board, Epson will not be responsible for any
consequences.
z If 2-color thermal paper is selected from the “Device Specific settings” dialog box,
2-color thermal receipt paper must be used in the printer.
z If the device is set to the power saving mode when 2ColorThermal is selected in the
PaperType combo box of SetupPOS, CapRec2Color property is set to FALSE. In
addition, if 2-color printing is performed with the device set to the power saving
mode, actual printing is single color.
