Function Define User-Defined Characters
ASCII [ESC] & <y> <c1> <c2> [x1 d1 … d(y x x1)] … [xk d1 … d(y x xk)]
Hexadecimal 1BH 26H y c1 c2 [x1 d1 … d(y x x1)] … [xk d1 … d(y x xk)]

defines user-defined characters from character code <c
1
> to <c
2
>. <y> and <x>
are the configurations of user-defined characters. <y> specifies the number of
bytes in the vertical direction. <x> specifies the number of bytes in the horizontal
direction. Character codes ranging from ASCII code 20H (32) to 7EH (126) can
be defined by <c
1
> and <c
2
>. Up to 19 user-defined characters can be defined.
Data (<d>) specifies a bit printed to one and not printed to zero. At the default,
user-defined characters are not defined, and the internal character set is printed.
Once the user-defined characters have been defined, they are available until
[ESC] @ or [ESC] ? is executed; the user-defined characters are redefined; the
power is turned off; or the printer is reset.
Function Cancel User-Defined Characters
ASCII [ESC] ? <n>
Hexadecimal 1BH 3FH <n>
Decimal <27> <63> <n>
Range 32 ≤ n ≤ 126
Description The [ESC] ? <n> command cancels the user-defined characters defined for
character code <n>. After the user-defined characters are canceled, the internal
character set is printed.
Function Select Character Font
ASCII [ESC] M <n>
Hexadecimal 1BH 4DH <n>
Decimal <27> <77> <n>
Range 0,1,48,49
Description The [ESC] M <n> command selects one-byte character font.
