NOTE: The print position within the printable area of the thermal elements for dots 257 to 512 is
shifted approximately 0.07 mm (.003") in the paper feed direction from the position for
dots 1 to 256. Be sure not to print a ladder bar code across both printable areas, as this
can cause variations in printing which are difficult to read. However, when the ladder bar
code is printed with level 2 of print density, the difference is only approximately 0.04 ~
0.05 mm (.0015~.0019”).

3) Vibration resistance: When Packed: Frequency: 5 to 55 Hz
Acceleration: 2 G
Sweep: 10 minutes (half cycle)
Duration: 1 hour
Directions: x, y, and z
No external or internal damage should be found after the

1.13 Installation
The TM-T88II series printer must be installed horizontally.
(Vibration during paper cutting and using a drawer should be considered. Take measures to
prevent the printer from moving. Affixing tapes are provided as an option.)
An optional hanging bracket can attach the printer to a wall. (Following the procedures
describes in the installation manual, install the wall mount and change the location of the paper
roll near-end sensor, then install the paper roll stopper and other parts.)
