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 print in the same print density.
Print Speed
The TM-T88IV has speeded its printing up to 200 mm/s at maximum. (TM-T88III: 150 mm/s)
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 43.)
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 43.), or set the
transmission speed higher in case of the serial interface. (See "Transmission speed (DIP
switch 1-7/1-8)" on page 36.)
