Different Kinds of Fields
Each type of field is defined to hold a certain type of data. You can define bar
code fields (with or without interpretive fields), human-readable fields, graphic
fields, line fields, or box fields. You must define the data you plan to print on
your label as a field in the label format.
Each field type gives you options for interpreting your data. The fields that
contain the most options are bar code fields and human-readable fields.
To design a label that best meets your needs, you should familiarize yourself
with the different kinds of fields that you can print. The following pages
describe the fields that will be most useful to you.
About Bar Code Symbologies
Your 4100 printer can print bar codes in a dozen symbologies. To use one in a
label design, see “Program Mode Command Descriptions” in Chapter 7 under
the c[n][,modifier1][,modifier2] [,modifier 3]; command. The 4100 printer can
print a bar code in the following symbologies: Code 39, Code 93, Code 2 of 5,
Interleaved 2 of 5, Codabar, Code 11, Code 16K, Code 49, Code 128, UPC, EAN,
and P. The following information comes from The Bar Code Book by Roger C.
Palmer.
Code 39
Code 39 is the first alphanumeric symbology ever developed and is widely
thought of as the standard non retail symbology. It is a discrete self-checking,
variable length symbology that can be readily printed in a variety of
technologies such as the automobile industry. Every Code 39 character has five
bars and four spaces. Of these nine elements, three are wide, and six are
narrow, making Code 39 a two-width code. Although there are only 43 data
characters in Code 39‘s character set, it is possible to encode all 128 ASCII
characters using Code 39‘s Full ASCII feature. A Code 39 symbol begins and
ends with an asterisk (*), which is this symbology‘s start and stop code. Each
character is separated from its neighbor by a loosely toleranced intercharacter
gap that contains no information. An optional modulo 43 check character is
defined for use in specific applications that require exceptional data security.
The Health Industry Bar Code Council (HIBCC) has adopted the use of this
check character for health care applications. As a general rule, the use of this
check character is encouraged.
