Printronix ThermaLine Series manual Ranging from row 1 to one less than the length

SR	Defines the starting row for the bar code. Enter a value
	ranging from row 1 to one less than the length of the
	form. Character row or dot row is specified based on
	the Scale command (page 4±88), or use the CP.DP
	format (page 4±7).
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 will
	not print with the data.
data field	The characters of the bar code data are restricted to
	exactly seven digits. If the 2± or 5±digit add±on data
	option is used, include this data at the end of the data
	field. The characters available for the data field are 0
	through 9 (30 through 39 hex, respectively).
PDF	Optional parameter to print the human readable data
	field. The data field prints automatically unless the
	PDF±suppress command is specified in the FONT
	parameter. The human-readable data field can be
	printed above or below the bar code symbol.
	This parameter is not allowed if a null data field is
	specified. If no PDF command is entered, the data
	field will print automatically in the default OCR±B
	font.
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.
