Print Bar Code (continued)
Second Variation Length of Byte Specified at Beginning of String
The value of m selects the bar code system as described in the table. When details
present in the print buffer, the printer processes the data following m as normal data.
The variable d indicates the character code to be encoded into the specified bar code
system. See the table. If character code d cannot be encoded, the printer prints the bar
code data processed so far, and the following data is treated as normal data.
