Confidential

ESC % n

[Name] Select/cancel user-defined character set
[Format] ASCII
Hex
Decimal
0 ≤ n ≤ 255
[Range]
[Default] n = 0
[Function] Selects or cancels the user-defined character set.
When the Least Significant Bit (LSB) is 0, the user-defined character set is canceled and
the internal character set is enabled.
When the LSB is 1, the user-defined character set is selected.
[Description] • Only the least significant bit of n is valid.
• When the user-defined character set has been released, the internal character set is
specified automatically.

[Range]
32 ≤ c1 ≤ c2 ≤ 126
0 ≤ x ≤ 9
0 ≤ d ≤ 255
k = c2 - c1 + 1
[Function] 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.
• d specifies the defined character data pattern.
[Description] • Consecutive character codes for multiple characters can be defined in one definition.
• " 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 dots in the character configuration
pattern (9 dots), the remaining dots on the right are spaces.
• 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.
• Only the most significant bit of the second data byte in the vertical direction can be
printed.
• Independent user-defined character definitions are possible for the fonts if the
character pattern is different in the international character sets.
