^B4
Code 49 Bar Code
Description The ^B4 command creates a multi-row, continuous, variable-length
symbology capable of encoding the full 128-character ASCII set. It is ideally suited for
applications requiring large amounts of data in a small space.
The code consists of two to eight rows. A row consists of a leading quiet zone, four symbol
characters encoding eight code characters, a stop pattern, and a trailing quiet zone. A separator
bar with a height of one module separates each row. Each symbol character encodes two
characters from a set of Code 49 characters.
•
^B4 has a fixed print ratio.
• Rows can be scanned in any order.
