CHAPTER 8 BAR CODE CONTROL - 5
3. DEFINITION OF PARAMETERS
This bar code command can have the following parameters in the parameter segment (n ... n). Parameters are
effective only within the single command sequence using the syntax ESC i n ... n \. They do not take effect in
any subsequent bar code commands. If any parameters are not specified, they take the default settings. The
last parameter must be the bar code data start identifier (“b” or “B”) or the expanded character data start identifier
(“l” or “L”). Other parameters can be specified in any sequence. The prefix of each parameter can be either a
lower-case or upper-case character, - for example, “t0” or “T0”, “s3” or “S3”, etc.
3.1. Bar Code Mode
n = “t0” or “T0” CODE 39 (default)
n = “t1” or “T1” Interleaved 2 of 5
n = “t3” or “T3” FIM (US-Post Net)
n = “t4” or “T4” Post Net (US-Post Net)
n = “t5” or “T5” EAN 8, EAN 13, or UPC A
n = “t6” or “T6” UPC E
n = “t9” or “T9” Codabar
n = “t12” or “T12” Code 128 set A
n = “t13” or “T13” Code 128 set B
n = “t14” or “T14” Code 128 set C
n = “t130” or “T130” ISBN (EAN)
n = “t131” or “T131” ISBN (UPC-E)
n = "t132" or "T132" EAN 128 set A
n = "t133" or "T133" EAN 128 set B
n = "t134" or "T134" EAN 128 set C
This parameter selects the bar code mode as above. When n is “t5” or “T5”, the bar code mode (EAN 8, EAN
13, or UPC A) varies according to the number of characters in the data.
3.2. Bar Code Style, Expanded Character Shading, Line Block Drawing & Box
Drawing Shading
Ÿ Bar Code Style
n = “s0” or “S0” 3 : 1 (default)
n = “s1” or “S1” 2 : 1
n = “s3” or “S3” 2.5 : 1
This parameter selects the bar code style as above. When the EAN 8, EAN 13 or UPC-A bar code mode is
selected, this bar code style parameter is ignored.
Ÿ Expanded Character shading
“S” 0 = White
1 = Black
2 = Vertical stripes
3 = Horizontal stripes
4 = Cross hatch
e.g. “S” n1 n2
n1 = Background fill pattern
n2 = Foreground fill pattern
If “S” is followed by only one parameter, the parameter is a foreground fill pattern.
