Printronix LQH-HWTM manual Replace n with a number ranging from 1 to

Code 128A, 128B and 128C

	b.	Replace n with a number ranging from 1 to
		512 to identify the bar code field. The SR and
		SC parameters specify the exact location of
		the bar code field identified by n.
	c.	Replace L with a number equaling the total
		number of characters in the field. (The actual
		data provided dynamically during the Execute
		Form mode can be less than L.)
	d.	The information for the data field is entered
		dynamically during the Execute Form mode.
		(Refer to “Execute Form: Dynamic Bar Code
		Data” on page 63.) Do not use the data field
		parameter to enter data when the BFn;L
		parameters are used. Refer to the data field
		description for available characters.
DARK	Optional parameter to produce darker bar codes.
	Enter DARK. Refer to “Dark Printing” on page 28
	for more information.
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 83),
	or use the CP.DP format (page 26).
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
	83), or use the CP.DP format (page 26).

(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 Enter the data for the bar code. A null data field (no characters) is permitted. Whenever a string of 4 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 either a Code A or Code B and returns to their respective 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 12, Table 13 and Table 14, beginning on page 113.
