Lexmark 248X, 249X manual 151, Minimum Minimum v1 Printer Model Value Values

v2 is the upper byte of V (quotient of V divided by 256).

v1, v2 define the bar height.

Use the following steps to calculate the values of v1 and v2:

1 Determine the approximate desired height (in inches) of the bar.

2 Let V = 2160 x (height in inches). Round V to the nearest whole number. 3 v1 is the lower byte of V (remainder of V divided by 256).

4

Example:

1 Desired height is 0.47 inch.

2 V = round (2160 x 0.47) = round (1015.2) = 1015. 3 v1 = remainder (1015 divided by 256) = 247, xF7 4 v2 = quotient (1015 divided by 256) = 3, x03

v1, v2 are subject to the following limitation:

	Minimum V	Minimum v1, v2
Printer Model	value	values
248x	270	x0E, x01
249x	288	x20, x01

Notes:

•If you try to use values less than the minimum values, the printer ignores your values and uses the minimum values.

•The vertical pitch for 248x printers is 1/72 inch. The vertical pitch for 249x printers is 1/180 inch.

c is the control flag.

c is a multi-purpose parameter. It has three bits that determine check digit, human readable character, and flag character position.
