^BU
UPC-A Bar Code
Description The ^BU command produces 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
produces the UPC/EAN symbologies at a magnification factor of 77 percent.
•
^BU 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.
