Define extended user-defined character set
ASCII
US & s c1 c2 [character 1 data] ... [character k data]
Hexadecimal 1F 26 s c1 c2 [character 1 data] ... [character k data]
Decimal
31 38 s c1 c2 [character 1 data] ... [character k data]
Values and ranges:
s = the number of dot rows in the character cell (maximum 64)
c = the ASCII codes of the first (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 define only one character, use the same code for both c1 and c2
j = s/8 = the number of bytes (vertically) in the character cell
k = c2 – c1 + 1 = the number of characters to be defined in this command string
[character i data] = [ni d1 ... d(j x ni)] for 1 ≤ i ≤ k
[character i data] = [ni d1 ... d(j 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 j x ni.
The bytes are printed down and across each cell.
Defines and enters downloaded characters into RAM. The command may be used to overwrite single characters. User-
defined characters are available until power is turned off or the Initialize Printer command (1B 40) is received.
Any invalid byte (s, c1, c2, n1, n2) aborts the command.
