Dene user-dened character set

ASCII ESC & s c1 c2 [character 1 data] ... [character k data]

Hexadecimal 1B 26 s c1 c2 [character 1 data] ... [character k data]

Decimal 27 38 s c1 c2 [character 1 data] ... [character k data]

Values and ranges:

s = 3, the number of bytes (vertically) in the character cell

c = the ASCII codes of the rst (c1) and last (c2) characters respectively

c1 = Hex 20–FF (20 is always printed as a space)

c2 = Hex 20–FF (20 is always printed as a space)

To dene only one character, use the same code for both c1 and c2

k = c2 – c1 + 1 = the number of characters to be dened in this command string

[character i data] = [ni d1 ... d(3 x ni)] for 1 ≤ i ≤ k

ni = the number of dot columns for the ith character, 1 ≤ ni ≤ 16

d = the dot data for the characters

The number of bytes for the ith character cell is 3 x ni.
