Bar Codes5–46
The same character must be used at both ends of the
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. Whenever a string of 6 or
more contiguous numeric digits are detected, the
IGP/PGL automatically inserts a Code C at the start of
the numeric string and outputs numeric digit pairs
packed into single bar code characters.
When the string is broken (non–numeric data or an
unpaired numeric digit occurs), the IGP/PGL
automatically inserts a Code B and returns to normal
C128B symbols. The length of the data field is
variable; however, the maximum length is usually
limited to 32 characters to minimize potential reading
errors. The data field can contain any of the characters
listed in Table 5–13 and Table 5–14, except the system
SFCC.
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.
