I2OF5 AND D2OF5
I2OF5 (Interleaved 2 of 5) is an interleaved code, used mainly in the
distribution industry. It supports numbers 0-9 only. It can use a
checksum digit, but the user must calculate and enter the checksum
manually as part of the code. I2OF5 uses start and stop characters,
which the printer generates automatically. Because of the interleaved
pattern, an even number of digits (including the checksum, if used)
must be placed in the bar code string. For example, 0123 is valid, while
123 is not valid.
D2OF5 (Discrete 2 of 5) is a numeric code, often used for envelope
identification and airline ticketing. Data is encoded by bar widths only,
with the spaces between bars only serving to separate the individual
bars. Five binary bits (three 0 and two 1) encode each character. The
binary bits are bar coded in sequential sets of five bars. The code uses
start and stop characters, which the printer automatically adds to the
printed code.
CODE39 and CODE39+
CODE39 is a widely used alphanumeric code that supports numbers
and characters 0- 9, A-Z, ".", space, "$", "/", "+" and "%". It does not
support lowercase characters. Code 39 is self-checking, and does not
normally use a check digit. An asterisk is used as a start and stop
character, and the printer automatically adds it to the bar code. The
asterisk does not normally print as part of the bar code subtext. If you
put an asterisk before and after the bar code data, it will appear with
the bar code subtext but will not be added to the code.
CODE39+ is the HIBC (Health Industry Bar Code) standard
symbology. It is similar to normal Code 39, except it uses an
automatically generated check digit. The check digit does not appear
in the bar code subtext.
CODE93
CODE93 is similar to Code 39. It can encode 48 different characters,
and with the use of control characters, typically encodes the entire 128
ASCII characters. Each encoded character in a Code 93 symbol is
represented by three variable width bars and spaces.
