PcOS Series 150
Set bar code
[GS] k <m> {information} [NUL]
The Series 150 Printer uses the same print functions to print EPOS bar
codes as the normal mode bar codes.
EPOS has two formats for bar codes. One is [NUL] terminated; the
other has a length field. If <m> is greater than 64, the next byte sets
the length in bytes. Only the [NUL] terminated command is supported
by the Series 150 Printer.
