The ESC ( B command is used to print barcodes. The format of this command is
as follows:
ESC ( B nL nH k m s v1 v2 c BarCodeData
nL nH Specify the number of data bytes to follow,
determined by the following equation:
(number of data bytes) = 6 bytes + BarCodeData bytes = ((nH × 256) + nL)
(where 6 bytes are k, m, s, v1, v2, and c)
nH = INT
number of databytes( )
256
nL = MOD
number of databytes( )
256
