Chapter 5: Bar Codes
The purpose of this chapter is to provide information and the formatting requirements of the
different bar codes that ar
e stored in the printer’s memory.
5.1 Generating Bar Codes
Bar codes that are stored in the printer are generated by using the CI, SW, SH and the AI
(when applicable) parameters of the Format Entry Command
(“^Fn)”). The CI parameter is
used to select the text equivalent code of the desired bar code while the SW, SH and AI
parameters control the size of the printed bar code.
5.1.1 CI Parameter
The CI or Conversion Identifier selects the bar codes that are stored in the printer by
entering the text equivalent code of the desired bar code. Refer to Table 1 or the
descriptions below, under the “Bar Code Types” section, for the available bar codes and
their equivalent codes. The text equivalent codes may be entered in either uppercase,
lowercase, or a combination or the two.
5.1.2 SW Parameter
When used in conjunction with bar codes the SW parameter is used to modify the Bar code
width by a multiple of the narrowest rendition. This means that a value of “1” will produce
the narrowest rendition related to the bar elements while a value of “3” would produce a Bar
code that is three times this width. The default value of “1” will be used if a Bar code is
selected and this field is left blank.
5.1.3 SH Parameter
When used in conjunction with bar codes the SH parameter selects the actual height,
measured in inches, of the desired bar code. This is a required field when used in
conjunction with bar codes.
5.1.4 AI Parameter
Some bar code types combine the use of ratios along with the SW and SH parameters to
create the different sizes of printed output. The bar codes that use the different ratios are
entered in a ratio format and are listed in the descriptions under the “Bar Code Types”
section. The ratio is required for the bar codes that utilize the different ratios and if omitted,
the bar code will not be printed.
For example:
“3:1” would be entered for the AI parameter for a bar code that allows a three
to one ratio with respect to the wide and narrow bars.
