Black Box PQ-8S Manual De Usuario

To print any of these bar codes,

use the following format:

¬B<type>,<height>,<width>,
<hr>,<chkd>,<ast>,<data>¬B

The bar-code command string

must contain all of these parameters,
even if the parameter is irrelevant
for the type of bar code being
printed. For example, POSTNET
comes in only one size, so, any
height or width specifications are
ignored. But the parameters for
height and width must be included
anyway.

¬B:  Identifies the strings as a bar
code command string.  ¬B must be
placed at the beginning and at the
end of the string.

<type>:  Specifies the bar code type
according to Table 6-1.

<height>:  Specifies the height of the
bar code. Height is expressed in
multiples of 2.5 mm (approximately
1/10 inch).  The height of the bar
code can range from 1 (2.5 mm) to
9 (22.5 mm) inclusive.

Height values are ignored if a

POSTNET bar code is being printed,
since POSTNET uses one standard
height. However, a valid value (1-9)
must be entered for the height
parameter to ensure the bar-code
command string is complete.

<width>:  Specifies the width of a
bar-code module. A module is
defined as a specific combination of
bars and spaces used to represent a
human-readable character.

By changing the width parameter,

you can determine the width of the
module and the thickness of the bars
and spaces.

Width parameters can range from

1 to 9. 

To determine the total length of

the bar code, simply multiply the
module length (found in the table
on the following page) by the
number of bar-code characters.

Example:  Using Code 3 of 9, you
want to bar code the word
“PRINTERS.”  Assume the PQ-8 also
generates a check digit and the 
start/stop characters. Setting the
width parameter to 2 will yield a total
bar code length of approximately 4
cm or about 1-1/2 inches.

Number of characters: 11 (8 letters

(PRINTERS) + 2 start/stop
characters + 1 check digit)
