5–109 Bar Codes
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 font type for UPC–A
bar codes is OCR–B; if no PDF command is entered in
the command format, the data field is printed
automatically in OCR–B. Entering X will also
designate the OCR–B type font. Enter N to select the
normal ASCII 10 cpi font; enter O to select the
OCR–A 10 cpi font. Enter S to suppress printing the
data field and the trailing lower portions of the UPC
bar code.
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.
