{1} is the Encoded Message.
{2} is the Banner heading.
{3} identifies the Symbology (MAXICODE) and lists the symbol's Mode.
{4} presents an approximate X-dimension.
Note: The reported X-dimension is approximate and based upon use of the
IT4410LR at 4.7 in (12 cm) (see "Reading Techniques" on page 1-1). If
you use different image engines, the X-dimension will vary. If you hold
the reader closer than 4.7 in (12 cm), it will have the effect of reporting a
larger than true X-dimension. Conversely, if you hold the reader farther
away than 4.7 in (12 cm), it will have the effect of reporting a smaller than
true X-dimension. Please contact HHP Application Support for additional
information. Refer to Chapter 3 for contact information.
{5} lists the Data Safety Margin. Because the Error Correction level for Maxi-
Code is fixed for each mode, this parameter is just the "Unused Error Cor-
rection," and is always between 0 and 100%.
{6} and {7} list the Horizontal & Vertical Print Growths, respectively.
Postal (Height-Modulated) Bar Code Symbologies
This section describes the height-modulated 2-state symbologies, Postnet and
Planet Code, used in the United States, as well as the 4-state symbologies used
in England, the Netherlands (“KIX”), Canada, Japan, and Australia. All dimen-
sions, where listed, are in inches for 2-state symbols and in millimeters for 4-
state symbols.
Postnet and Planet Code
