Chapter 4: Programming Commands 52 Revision C 12/09
A798-PG00001C
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
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 (s, c1, c2, n1, n2) aborts the command.
Select or cancel underline mode
ASCII ESC - n
Hexadecimal 1B 2D n
Decimal 27 45 n
Value of n: Decimal Hex
0, 48 30 = Cancel underline mode
1, 49 31 = Select underline mode
2, 50 32 = Select double thickness underline mode
Default: 0 (Cancel underline mode)
Turns underline mode on or off. Underlines cannot be printed for spaces set by the horizontal tab, set absolute start
position, or set relative print position commands.
This command and the Select Print Mode(s) command (1B 21) turn underline on and off in the same way.
Exceptions
This command is ignored if n is out of the specified range.

In A793 emulation, this command is unrecognized and the parameter n is put into the print buffer.
