Bar Codes All bar codes supported by the EPL2 language

have associated industry specifications that the

programmer should be aware of and adhere to.

The programmer needs to consider bar code

features and requirements when choosing and

using a bar code for different applications.

Some of the features and requirements that

need consideration are listed below:

❏Data used by the application are per the bar

code specification (numbers only, alphanu-

meric, alphanumeric and special characters,

etc.).

❏Minimum and maximum number of charac-

ters allowed or required per bar code.

❏Density or magnification of a given bar code

type.

❏White area required around bar codes (the

“Quiet Zone”).

❏The bar code must print within the image

buffer (printable area of the label).

Bar Code Orientation Tip

To help ensure that generated bar codes are read-

able by the widest variety of bar code readers, print

bar codes in the “Picket Fence” orientation versus

the “Ladder” orientation.
