TM-T88/T88P (TM-T85/T85P) Information Manual
❏ ESC i, ESC u, and ESC v are supported only by TM-T85/T85P.
These commands are not recommended. (There are other commands which support the
same functions of the above commands.) For the TM-T88/T88P, GS V and GS r can be used
as the above commands.
❏ The functions of GS V and ESC c 5 are different for TM-T88/T88P and TM-T85/T85P.
❏ For DLE EOT, GS a and GS r, conditions of status changes for paper roll sensor and
automatic recovery error are different for TM-T88/T88P and TM-T85/T85P.
Using Bit Value Tables
For each command that has a complex method of determining the variable n, there is a table showing
how to calculate the variable in three numbering systems: binary, hexadecimal, and decimal.
When you look at the table, first find the value of each component of the variable. Then add the
values of the components together to determine the value of the variable n.
For example, here is how you would use the table below, which selects the print mode, to combine
double height, double width, and underline. In the table, you see that bit 4 on (or hex 10 or decimal
16) turns on double height, bit 5 on (or hex 20 or decimal 32) turns on double width, and bit 7 on (or
hex 80 or decimal 128) turns on underline mode.
To combine all three, turn on bits 4, 5, and 7, which is 10110000 in binary. Or you can add the hex
values 10, 20, and 80 for the hex sum of B0, or you can add the decimal values 16, 32, and 128 for the
decimal value of 176.
Therefore, you send the following to turn on double height, double width, and underline, depending
on the numbering system used:
ASCII ESC ! n
Hex 1B 21 B0
Decimal 28 33 176
Bit Off/On Hex Decimal Function
0
Off 00 0 Character font A selected.
On 01 1 Character font B selected.
1, 2 — — — Undefined.
3
Off 00 0 Emphasized mode not selected.
On 08 8 Emphasized mode selected.
4
Off 00 0 Double-height mode not selected.
On 10 16 Double-height mode selected.
5
Off 00 0 Double-width mode not selected.
On 20 32 Double-width mode selected.
6 — — — Undefined.
7
Off 00 0 Underline mode not selected.
On 80 128 Underline mode selected.
