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
ni = the number of dot columns for the ith character, 1 ≤ ni ≤ 16
d = the dot data for the characters (bit gets printed to 1 and not printed to 0)
The number of bytes for the ith character cell is j x ni .
The bytes are printed down and across each cell starting from the left side.
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 ) aborts the command.

User-defined characters can be set for each pitch independently by selecting the pitch using the 1B
21 command.
