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 active user-defined character set

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

ASCII	US i n
Hexadecimal	1F 69 n
Decimal	31 105 n
n = 0 - 127

Set high order bit of n 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.
