Lexmark 248X, 249X manual 115, Downloading an NLQ II Character Set

Downloading an NLQ II Character Set

The 248x printers can download two sets of NLQ II characters. The first set is initialized to a Courier-like font, and the second to a Courier italic-like font. Since there are two download areas, you must use a Select Print Mode, ESC I, before downloading to select between the two download areas. To select the first area, use the ESC I x07 command. For the second download area, use the ESC I x0F command.

Downloading NLQ II character set is performed using the ESC = command similar to the Draft/NLQ download command.

Syntax:	ESC	=	count1	count2	font id start
Decimal:	27	61	count1	count2	21	start
Hex:	1B	3D	count1	count2	15	start

Part One: Calculating Count 1, Count 2

Count 1, count 2	specify the number of bytes to be downloaded.
Font ID byte	is the value assigned to identify the type of font data. The
	ID for NLQ II is 21 (x15).
Start	The start code is the ASCII value (code-point) for the first
	downloaded character. It must be in the range of x00 to
	xFF. You can start your downloaded character set at any
	point in the character table. The download characters
	replace normal characters starting at this code-point. For
	example, to download a character set that replaces char-
	acters starting with the uppercase letter ’A’, use a start
	code- point equal to 65 (x41), ’A’. All character codes
	within the same download command must be consecu-
	tive from the start code-point.
