TWO-DIMENSIONAL BAR CODES
Introduction
A two dimensional bar code can be regarded as a “por-
table database.” For example, if a package has a serial
number encoded with a linear bar code, you could scan
the serial number, look up the number in a computer
system, and gather the information about that package.
If the computer system was unavailable for any reason
the information you were looking for would also be un-
available A 2D bar code, however, can contain several
different fields of information in them, essentially a data-
base attached to a package.
The first 2D bar code was just an extension of a one-
dimensional bar code. The user could stack several
Code 39 bar codes on top of another. These types of
codes are called “stacked symbology” or “multi-row
codes”. Development of scanners capable of 2D scan-
ning allowed use of more compact and useful symbolo-
gies like PDF417 from Symbol and MaxiCode from the
United Parcel Service.
Zebra mobile printers have capabilities to print PDF417
and MaxiCode symbols. If your application requires the
use of PDF417 or MaxiCode symbols, we highly recom-
mend acquiring the universal symbol specification to
assist your programming. The specifications include
suggestions on how to structure your data in the code to
make it easier to use.
Please note that you must load a special application
before using PDF417 or MaxiCode on your Zebra mobile
printer. The standard application loaded in your printer
does not support the ability to print these bar codes.
Contact the Help Desk for more information on how to
load this application.
