Define user-defined characters
Format: ASCII: ESC & s n m a d1 d2……db
Decimal: 27 38 s n m a d1 d2……db
Hex:
1B 26 s n m a d1 d2……db
[Description]
This command is used for self-defining characters. The meaning of each parameter is shown as follows:
S:
The number of longitudinal byte. Here S=1,2. When n=1, define 7×7 character.
When n=2, define 7×9 or half-size character.
N: Starting ASCII code of user-defined character set
。
n
≥
32.
M: Ending ASCII code of user-defined character set
。
m
≤
127. The number of user-defined
characters is m-n+1, and the maximum number is 96. When user defines only 1
character, m=n.
A: The byte number of user-defined characters.
d1 d2…db: The data of user-defined characters. Every character has s×a bytes. m-n+1 bytes
altogether have
（
s×a
）
×
（
m-n+1
）
bytes.
The user-defined characters after being defined will be valid all the time until they are
defined again or the printer is turned off.
The format of user-defined characters is shown as follows:
b7
d1 d4 …
d2 d3 …

[Description]
This command is used for setting dot matrix figure mode (m) and setting the transverse dots number

of dot matrix figure.

n2 is hexadecimal figure with two bits. n1 is low byte and n2 is high byte. n1
，
n2 is used for denoting
the transverse dots number of figure printed by “ ESC
* “ command. This value should be within the
number of maximum line-width dots.
When m=0
，
normal printing is selected, the maximum number of printing dots is 210.
When m=1
，
half-dot printing is selected, the maximum number of printing dots is 420. On this condition
the adjacent dots cannot be “1” at the same time.
