Note: The OCR character set disable command, [ESC] y <12>, also
restores the character set to the original definition.

x
k
)] command defines user-defined characters from character code <c
1
>
to <c
2
>. <y> and <x> are the configurations of a user-defined character.
<y> specifies the number of bytes in the vertical direction. <x> specifies
the number of bytes in the horizontal direction. Character code ranges
from 32 (20H) to 126 (7EH) can be defined by <c
1
> and <c
2
> . Up to 32
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] $ is
executed; the user-defined characters are redefined; the power is turned
off; or the printer is reset.
Each internal font (draft, large draft, and NLQ) has its own 32-character
storage area. If possible, the currently selected font will be used to select
which user-defined font is defined. If the font being defined is not suitable
for the currently selected mode, a suitable font will be temporarily
selected for the definition. If <y> = 2, the 12 x 12 draft font or the 12 x 14
large draft font can be defined. If <y> = 3, only the 16 x 24 NLQ font can
be defined. If <y> = 2 and the NLQ font is active, the large draft user-
defined font will be loaded. If <y> = 3 and a draft font is active, the NLQ
user-defined font will be loaded.
