Using ,m2 and ,m3 to Group Symbols
,m2 and ,m3 define symbols that are part of a group. ,m2 is the position of
the current symbol in the group, and ,m3 is the total number of symbols in
the group. For example, a setting of [,m2,m3] to [,2,5] indicates that the
current symbol definition is the second in a group of five. Both ,m2 and ,m3
range from 1 to 15, with a default of 1.
Note: If you are using groups of symbols with the ,m2 and ,m3 variables, make
sure ,m2 (the position in the group) is never greater than ,m3 (the total number of
symbols in the group).
The printer does not check to ensure that you define all positions of a group.
For example, if you set ,m3 to 5, and you define only three positions, the
printer prints the three. When you scan these symbols, the scanner waits for
all five symbols and will not be able to transmit the data.
Defining Height and Width for Code One
Code One modules must be square. Therefore, when you define a field for
Code One, you only need to enter one value for both the height and width
magnification. If you enter more than one value, the printer uses the last
value for both height and width and ignores all previously entered
magnification values. If you do not enter a value, the printer uses a default
value of 3 for both height and width magnification.
Using Groups of Code One Symbols
You can use groups of Code One symbols to encode data so that you can
scan separate symbols more efficiently. When you scan a group of symbols,
the scanner accumulates the data from all members of the group and
transmits the data as if it came from a single symbol.
