UPC/EAN Extensions
The ^BS (UPC/EAN extensions) instruction is the 2- and 5-digit add-
on used primarily by publishers to create bar codes for ISBN’s (Inter-
national Standard Book Numbers, issued by R.R. Bowker). These
extensions are handled as separate bar codes.
Although compatible with the UPC symbol, these extensions cannot
be mistaken for a UPC symbol or for part of the UPC symbol by scan-
ners designed to read only standard UPC symbols. This is because the
UPC/EAN extension has only one guard pattern (on the left, encoded
1011) and its characters are separated by delineator characters.
Print Ratios Supported: Fixed Ratio.
^FD (Field Data) Limitations: Exactly 2 or 5 characters. ZPL II
automatically truncates or pads on the left with 0’s to achieve
required number of characters.
