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.
