[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.
When only one character is desired, use c1 = c2.
• x specifies the number of dots in the horizontal direction.
[Details] • The range of definable character codes extends from 20H to 7EH among the ASCII codes.
• Consecutive character codes for multiple characters can be defined in one definition. When
specifying only one character, specify c1 = c2.
• "d" is definition data that indicates the pattern for "x" dots in the horizontal direction starting
from the left edge. If "x" does not satisfy the number of dots in the character configuration
pattern, the remaining dots on the right are spaces.
• The number of bytes required to download a character definition for one character is "y" × "x."
• In the definition data, a "1" represents a dot that is to be printed, and a "0" represents a dot
that is not to be printed.
• Independent downloaded character definitions are possible for each font. The font is
selected by the
ESC !
command.
• The defined downloaded characters are cleared in the following circumstances:
1) W hen
ESC @
is executed.
2) When deleted by
ESC ?.
3) When the printer is reset or turned off.
• The maximum number of characters that can be defined is 19 (8 for the multilingual
supporting model).
