(7) Defining the download characters (ESC & s n m a {D1 D2 ~ Dn})

Code : [1B]h + [26]h + s + n + m +a + Dn

*{s = 03}

{20 ≤ n ≤ 7E} {20 ≤ m ≤ 7E}

{For the Font A; 0 ≤ a ≤ 0C, For the Font B; 0 ≤ a ≤ 09} The data is described with the hexadecimal code.

Defines the font for the download characters of alphanumeric characters.

•"s" denotes the number of bytes in the vertical direction.

•"n" denotes a start character code, and m denotes an end character code. When defining only one character, n should be equal to m (n = m).

•Definable character codes are ASCII codes, totally 95 characters ranging from <20>H to <7E>H.

•"a" denotes the numberof dots in the horizontal direction to be derection to be defined.

•"Dn" is the data to be defined and denotes a pattern corresponding to "a" dot in the horizontal direction from the left end. The right remaining pattern is filled with space.

•Once the download characters are defined, they remain effective until redefinition, execution of ESC @, execution of GS *, or power -off.
