HPIIISi TWINAX CARD
<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 (it can range from 1 to 9), you can
determine the width of the module and the thickness of the bars and
spaces.
To determine the total length of the bar code, simply multiply the module
length (found in Table 7-2) by the number of bar-code characters.
NOTE
Be aware that the table gives rounded values only.
Example: Using Code 3 of 9, you want to bar-code the word “PRINTERS.”
Assume the Card 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

":
• Number of characters: 11
(8 letters [“PRINTERS”] +
2 start/stop char
1 check digit)
• Module width (from Table 7-2):
3.6 mm (0.14")
• Calculation:
11 x 3.6 mm = 39.6 mm =
3.96 cm; or
11 x 0.14" = 1.54"
Width parameters are ignored when printing POSTNET bar codes, since
POSTNET uses one standard width. However, a valid value (1 to 9) must be
entered for the width parameter to ensure the bar code command string is
complete.
