^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.
