XBCP 1 — specify narrowest element width
Format
XBCP 1, element-width;
Parameter
element-width:
narrowest bar and space width:
More than or equal to 1 dot. If less than 1 dot, truncated to 1 dot. Default is 3 dots.
Function
PDF417 supports 8 different bar and space widths. The each width is a multiple of 1 to 8
times of the narrowest element width. The XBCP command set to mode 1 specifies the
narrowest element width (narrowest bar width) in the current unit as designated by a
UNIT command.
In the following example, the element width is set to .02 inches as the default unit is
inches. Minimum width allowed by the printing system is 1 dot. Minimum readable
width is probably higher. Minimum width meeting AIM recommendation for open
systems is 3 dots. After the first example has been printed, the printing system moves
cursor 1 inch down to print another example in which the minimum element width is
reverted to its default (3 dots).
