readable data field. Enter PDF to print the data field. If
the parameter is not used, the human readable data will

field was specified.
LOC Optional parameter to identify the location of the
printable data field. The default value is B, locating the
human readable data below the bar code. A locates the

printing the 0.1–inch high data, the height of the bar
code body is reduced 0.1 inch.
FONT Optional parameter to select the font for the human
readable data field. The default value, N, selects the
normal ASCII 10 cpi font. Enter O to select the
OCR–A 10 cpi font; enter X to select the OCR–B 10
cpi type font.

STOP is not entered, an error message results.
