Printronix ThermaLine Series manual Loc, Font

SC	Defines the starting column of the bar code. Enter a
	value ranging from column 1 to one less than the width
	of the form. Character column or dot column is
	specified based on the Scale command (page 4±88), or
	use the CP.DP format (page 4±7).
D	The printable character (delimiter) identifying the start
	and finish of the data field. Enter any printable
	character other than a slash (/), the SFCC, or a
	character used within the data. The same character
	must be used at both ends of the data field, but it is not
	printed with the data.
data field	Contains the bar code characters. 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 is 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 is N, selecting
	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.
