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 (c 1) and last ( c 2) characters respectively
c 1 = Hex 20–FF (20 is always printed as a space)
c 2 = Hex 20–FF (20 is always printed as a space)
To define only one character, use the same code for both c 1 and c 2
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
The number of bytes for the ith character cell is j x ni.
The bytes are printed down and across each cell.
See the illustration.
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 (

Select active user-defined character set
Selects user-defined character set number for download or printing. The default at power on is 0.

to configure user-defined character set number as the default. To configure the printer to print from
the user-defined character set at power, send 1F 3 0F 01 and reset the printer. Information will print on the first diagnostic
page.
