Code 128 Bar Code
Function Characters
The printer supports code 128 function control
characters (FCN#). Multiple FCN#s, TTs, TDs
and “DATA” strings can be concatenated, al-
lowing them to be inserted anywhere within the
symbol.
FCN2, FCN3 and FCN4 are illegal in code
128 mode C (p
4
= 1C) and will result in a syn-
tax error.
Please refer to the Code 128 standard for a de
-
scription of function characters FNC1 through
FNC3.
“Standard” Code 128 can encode all 128 stan
-
dard ASCII characters (0-127). Function char
-
acter FCN4 provides a means of also encoding
extended ASCII characters (128-255). It directs
the reader to add 128 to the value of each af
-
fected character before transmitting it.
Two consecutive FCN4s toggle between stan
-
dard and extended ASCII mode for all succeed
-
ing data characters (until the end of the symbol,
or until another pair of s is encountered). This is
referred to as latching into extended ASCII
mode or latching into standard ASCII mode.
