Tally Genicom 6600 manual Set Barcode Density

Chapter 7 Control Sequences

^W - Set Barcode Density

Sets the print densities and dot-making rules for Barcode printing thereby affecting print speed, symbol length, and readability through white:black and wide:narrow ratios.

For typical applications, the default values produce fully readable Barcode; however, a range of settings is provided to accomodate softer papers or drier ribbons, and to optimize size or throughput for special applications.

Command ^W (unit width);(centers);(dots)NL

Arguments

(unit width)	Unit bar or space width in 600th inch increments
	(400th if dots = 3). Range 9 to 13 default = 11.
(centers)	Center-to-center dot spacing along the length of the
	bars in 600th inch increments. Range 4 to 10,
	default = 5.
(dots)	Number of dots per unit bar or space. Range 1 to 3,
	default = 1.
	When dots = 1, the bar width is one printed dot per
	Barcode unit width. The bar-to-bar space is one
	unprinted dot per unit width.
	When dots = 2, the number of dots for an N wide
	bar is 2N1. An N wide space is 2N + 1.
	When dots = 3, the number of dots for an N wide
	bar is 3N1. An N wide space is 3N+1.
	Printing speed is directly proportional to the values
	of unit width and centers, and print speed is half as
	great for dots = 2 or 3 as for dots = 1. The default
	print speed is 36 inches per minute.
