[Description]
Defines user-defined characters
y specifies the number of bytes in the vertical direction.
c1 specifies the beginning character code for the definition, and c2 specifies the final code.
X specifies the number of dots in the horizontal direction.
[Details]
The allowable character code range is from ASCII code <20>H to <7E>(95characters).
It is possible to define multiple characters for consecutive character codes.
If only one character is desired, use c1 = c2.
d is the dot data for the characters. The dot pattern is in the horizontal direction from the left side.
Any remaining dots on the right side are blank.
The data to define a user-defined character is (y
×
x) bytes.
Set a corresponding bit to 1 to print a dot or 0 to not print a dot.
This command can define different user-defined character patterns by each fonts. To select a
font, use ESC !
A user-defined character and a downloaded bit image cannot be defined simultaneously.
When this command is executed, the downloaded bit image is cleared.
The user-defined character definition is cleared when:
①
ESC @ is executed.
②
ESC ? is executed.
③
FS q is executed.
④
GS * is executed.
The printer is reset or the power is turned off.
⑤
When the user-defined characters are defined in font B (9 x 24), only the most significant bit of
the 3rd byte of data in vertical direction is effective.
