The following apply to both
GS k <m> <dl> … <dk> NUL
GS k <m> <n> <dl> … <dn>:
If the horizontal width exceeds the printing area, the printer only feeds the paper. These
commands feed as much paper as necessary to print the bar code according to the GS h command.
These commands are enabled only when no data exists in the print buffer. When data does exist in
the print buffer, the printer processes the data following <m> as normal data. After printing a bar
code, the print position is set at the beginning of the line. These commands are not effected by
print modes (emphasized, underline, character size, etc.)
Note:
Barcode 39 allows the “*” character to be used as a start and stop flag. If the “*” is used, the
length specified must be at least as long as the desired barcode.
