This sequence prints the bar code symbol according to the previous selection. If you want to print more
than one bar code symbol of the same type and height, GS n defines the distance from the beginning of
the line or between two bar code symbols in multiples of 1/60 or 1/90 of an inch, depending upon the
selected barcode density (120 or 180 dpi). At the end of the line EM must close this command.
