The sample above produces three labels. The first is formatted
with the commands between L and E. The next two labels
print with the replacement data contained in the U
commands (see E and G). The bar code is the same
length: 3 digits and nine spaces.
Truncated Length Replacement Field Functions – A variant of the U command
includes the truncate option “T”, where dynamic data shorter than the originally defined
field length will not be padded and the original maximum field length is maintained for
subsequent replacements.
Syntax:
UTnnss…s
