This sequence causes the bar code symbol to be printed according to the Bar Code Selection command.
Sequential bar codes of the same type and height may be printed. GS N# defines the distance from the
beginning of the line or between two bar code symbols in multiples of 1/72 of an inch. This command must
be closed with an EM character.
Note: Bar code symbols will print over any descenders in the previous character box if any text is present.
Example 1:
Print an EAN-8 bar code symbol, one inch from the right margin with the data set of 12345678.
