Select Character Set

Selects the character set. The character sets cannot be used together on the same line. When

an undefined RAM character is selected, the Code Page 437 character is used. See

“Appendix B” for the character sets.

Hexadecimal Decimal ASCII Value of n Default

1B 25 n 27 37 n ESC % n

0 = Code Page 437

1 = User Defined (RAM)

2 = Code Page 850

Define User-Defined Character Set

Defines and enters downloaded characters into RAM. It may be used to overwrite single

characters. The user-defined characters are available until power is turned off, the Initialize

Printer (1B 40) command is received, or a downloaded bit image (1D 2A) is defined. User-

defined characters and a downloaded bit image cannot be used at the same time. The

command clears bit image logo data from RAM. Any invalid byte (s, c1, c2, n1, n2) aborts

the command.

Hexadecimal Decimal ASCII

1B 26 s c1 c2 n1 d1 ... nn dn 27 38 s c1 c2 n1 d1 ... nn dnESC & s c1 c2 n1 d1 ... nn dn

s = 3, the number of bytes (vertically) in the character cell

c = the ASCII codes of the first (c1) and last (c2) characters respectively

c1 = Hex 20-FE (20 is always printed as a space)

c2 = Hex 20-FE (20 is always printed as a space)

To define only one character, use the same code for both c1 and c2

n = the number of dot columns for the nth character as specified by n1 . . . nn

n = 0-10 (standard pitch), 12 and less accepted but ignored

n = 0-8 (compressed pitch), 12 and less accepted but ignored

d = the column data for the nth character as specified by d1 . . . dn

The number of bytes for a character cell is s x n1

The bytes are printed down and across each cell

See the illustration.
