p3 - Human Readable Enable
An argument of 1 turns on the human-readable line, while 0 turns it off. The default is on. When
the human readable line is enabled, it is printed in the font specified by parameter p12. There is
0.1" between the bottom edge of the bar code and the top of the characters in the human-
readable line.
Element Widths
The default element widths are the narrowest that we recommend for consistent readability.
The argument units for horizontal bar code element widths are 1/120 inch. The print wire diameter
is 1/72 inch; a printed dot is about 1/60 inch in diameter. This is the finest line that the printer can
make. The printer accepts an element width of 1 as a valid argument, but the actual width of the
resulting element is 1/60 inch, the same as if you had specified a width of 2.
If the element width argument is greater than 2, then the printer rounds down odd numbers. A
width argument of 5 produces the same result as a width argument of 4.
p4 - Narrow Bar Width
Argument units are 1/120 inch if the bar code is horizontal (0 o or 180 o rotation) or 1/144 inch if the
bar code is vertical (90 o or 270 o rotation). The default is 2.
p5 - Wide Bar Width
Argument units are 1/120-inch increments if the bar code is horizontal or 1/144 inch if the bar
code is vertical. The default is 6.
p6 - Narrow Space Width
Argument units are 1/120-inch increments if the bar code is horizontal or 1/144 inch if the bar
code is vertical. The default is 2.
p7 - Wide Space Width
Argument units are 1/120-inch increments if the bar code is horizontal or 1/144 inch if the bar
code is vertical. The default is 6.
Wide space and wide bar are both set to the smaller of the two values. This sets the proportion
of the large to small the same for spaces as it is for bars.
