^BU
UPC-A Bar Code
Description: The ^BU command is a fixed length, numeric symbology. It is
primarily used in the retail industry for labeling packages. The UPC-A bar code has
11 data characters. The 6 dot/mm, 12 dot/mm, and 24 dot/mm printheads produce
the UPC-A bar code (UPC/EAN symbologies) at 100 percent size. However, an 8
dot/mm printhead will produce the UPC/EAN symbologies at a magnification factor
of 77 percent.
^BI supports a fixed print ratio.
Field data (^FD) is limited to exactly 11 characters. ZPL II automatically truncates or
pads on the left with zeros to achieve required number of characters.
