Definition of Parameters
This bar code command can have the following parameters in the parameter segment (n ... n). As
parameters are effective within the single command syntax ESC i n ... n \, they don't apply in the bar code
commands. If certain parameters are not given, they take the preset settings. The last parameter must
be the bar code data start ('b' or 'B') or the expanded character data start ('l' or 'L'). Other parameters
can be given in any sequence. Each parameter can start with a lower-case or upper-case character, for
example, 't0' or 'T0', 's3' or 'S3' and so one.
