* You should only use ,m2 = 0 or 1 if your labels do not have enough space for
more error correction characters. Usually, these values are not recommended.
† The printer reserves ,m2 = 6, 7, or 8 for special applications where the symbol
is subject to damage and requires a higher level of error correction.
‡ ,m2 = 9 lets the printer set ,m2 to the recommended value for each symbol
based on the number of characters. An ,m2 value of 9 is the default setting.
Using ,m3 to Set the Truncate Flag
,m3 is a truncate flag that indicates whether to print the symbol in
truncated form. If truncated, the symbols print without right row
indicators and with only a one-module wide stop character. The values for
,m3 are 0 to disable truncating and 1 to enable truncating. The default is
0. To minimize errors and maintain the best reading performance,
Intermec recommends that you leave ,m3 equal to 0.
This table shows the approximate data capacity (maximum number of
characters allowed) for the three character sets.
Data Capacity per Character Set
Character Set Data Capacity
Full ASCII 1108
Alphanumeric 1850
Numeric 2725
Note: 2D symbols encode data by compressing it in different amounts.
Therefore, use these values as guidelines. The exact data capacity varies
with the actual data being encoded.
