The command selects a bar code system and prints the bar code. The value of m selects
the bar code system as follows:
m Bar Code System Number of Characters Values of d
65 UPC-A
fixed, 11 ≤ n ≤ 12 48 ≤ d ≤ 57 (ASCII numerals)
66 UPC-E
fixed, 11 ≤ n ≤ 12 48 ≤ d ≤ 57
67 JAN13 (EAN)
fixed, 12 ≤ n ≤ 13 48 ≤ d ≤ 57
68 JAN8 (EAN)
fixed, 7 ≤ n ≤ 8 48 ≤ d ≤ 57
69 CODE39 variable
48 ≤ d ≤ 57,
65 ≤ d ≤ 90 (ASCII alphabet),
d = 32, 36, 37, 43, 45, 46, 47
(ASCII special characters),
d1 = dk = 42 (start/stop code is
supplied by printer if necessary)
70 Interleaved 2 of 5
(ITF)
variable (even number)
48 ≤ d ≤ 57
71 CODABAR
(NW-7)
variable
65 ≤ d ≤ 68 start code,
48 ≤ d ≤ 57,
d = 36, 43, 45, 46, 47, 58
This command is valid only at the beginning of a line. When data exists in the print buffer,
the printer processes the data following m as normal data.
The variable n indicates the number of bytes of bar code data, and the printer processes n
bytes from the next character data as bar code data.
If n is out of range for a fixed length bar code system, the printer will attempt to encode the
following data, but an invalid bar code pattern may result.
The variable d indicates the character code to be encoded into the specified bar code
system.
If character code d cannot be encoded, the printer prints the bar code data processed so
far, and the following data is treated as normal data.
If the encoded bar code pattern exceeds one line, the printer does not print the excess
data.
