data field, but it will not print with the data.

data field

Enter the data for the bar code. A null data field (no

characters) is permitted. The length of the data field is

variable; however, the maximum length is usually

limited to 32 characters to minimize potential reading

errors.

PDF

Optional parameter to enable printing of the human

readable data field. Enter PDF to print the data field. If

the parameter is not used, the human readable data will

not print. This parameter is not allowed if a null data

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

printable data field above bar code. To compensate for

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

Ends the Bar Code command while the IGP/PGL

continues in the Create Form Mode. Enter STOP. If

STOP is not entered, an error message results.
