[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>H (95 characters).
• 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 FS q is executed.
③ GS ∗
∗∗
∗ is executed.
④ ESC ? is executed.
⑤ The printer is reset or the power is turned off.
• When the user-defined characters are defined in font B (9 × 17), only the most significant bit
of the 3rd byte of data in vertical direction is effective.
