more than 256 characters.)

Figure 40 Data Maxicode Example
Note: The normal Select barcode Width and Select Barcode height
commands do not affect Maxicode barcodes. The rules governing how
the barcode is printed do not allow variations in the aspect ratios. There
are Maxicode control commands that will allow some control over how the
barcode is printed.
Note: GS1 encoding is not supported by Maxicode.
MaxiCode Mode 2 and 3 Structured Carrier Message
MaxiCode Mode 2 and Mode 3 are generally use as a destination sorting symbol. In
these modes, the primary message is always data specific and encodes postal code,
country code and service class. The three primary data elements should be supplied in
the above order separated by GS (Group Separator - ASCII 29) immediately followed by
the secondary message contents.
There are two commonly used message formats when using Mode 2 and Mode 3:
Messages Beginning with "[)> RS 01 GS yy"
Messages which begin with the seven encoded data characters"[)>RS01GSyy" conform
to particular open system standards and has the following structure:

[)>RS (Message Header)

01GS (Format Header)
o
2-digit representing the year (yy) of a date
