Sato provides two methods to print MaxiCode bar codes. The final method uses two Sato unique
commands

DESCRIPTOR DATA
]
This escape sequence is used to describe not only what bar code to print, but also all of the
parameter settings required to build the bar code. The first two bytes of this command always
designate the symbology. The remaining byte is then interpreted to specify the mode. # is the
number of bytes of descriptor data. The descriptor data for MaxiCode would be the binary string
00 02 01 (for mode 1), 00 02 02 (for mode 2), and so on.

BAR CODE DATA
]
This new PCL 5 command is used to transfer a raw block of bar code data to be encoded. The
bar code data is encoded according to what was specified in the last valid Bar Code Descriptor
command received. If no valid Descriptor is sent, then this command is ignored and the data is
flushed. # is the number of bytes of bar code data.

Below is the header definition of the bar code descriptor for MaxiCode:
Symbology ID bytes 0 and 1: (Required = 00 02x)
These two bytes signify the symbology. For MaxiCode, these two bytes must
be 00x and 02x.
Mode: (Default = 02x)
This field designates what mode to use when interpreting the input data. Valid
modes are (in hex).
