If double height and double width are set at the same time quadruple character will be
formed.
All of the printed characters will be underlined except for the 90
°
rotated characters and
spaces created by horizontal tab.
Underline width is determined by the value set in [Underline set/reset] section.
The default value is “1”.
Different sizes of character mixed such as double width and normal size can be printed.
The default value of “n” is [00]h.
6) Down load characters set/reset : <<ESC % n>>

Explanation : Only LSB (b0) is valid for “n” value. LSB (b0) has the following
meanings.

Definition of download character( such as alpha numeric).
1. “s” indicates a number of bytes in a vertical direction and “a” is a number of dots
in horizontal direction.
2. “n” indicates the start character code, and “m” means the end character code. If
only 1 character should be defined, then n = m.
3. Definable characters are from <20>h to <7E>h in ASCII code (95 characters).
4. “Dn” indicates the data to be defined. It indicates the “a” dots pattern from the left.
Remaining area on the right of a character is filled with spaces.
5. Once a download character is defined, it remains valid until the download
character is redefined, printer is initialized, reset signal is input, or the power is
turned off.
