HPIIISi TWINAX CARD
<hr>
:
Identifies whether human-readables are printed or not. Human-readable
characters are printed underneath the bar code. Valid values are:
0 = Do not print human-readables.
1 = Print human-readables.
<chkd>
:
Indicates whether the Card automatically calculates a check digit and
causes it to be printed.
Some bar codes (Code 128, POSTNET, UPC A, EAN 8, and EAN 13)
require a check digit, so the Card automatically generates one and adds it
to the bar-code data. If any of these bar codes has been selected, the
<chkd> selection is ignored by the Card. However, one of the following
values must be entered to ensure that the bar-code command string is
complete and valid. The options for the <chkd> parameter are:
0 = Do not calculate/add a check digit.
1 = Calculate a check digit and add it to the bar-code data.
<ast>
:
Specifies whether start/stop characters are automatically generated or
manually added. This parameter only applies to bar-code type Code 3 of 9.
For all other bar-code types, the start/stop characters are automatically
generated by the Card and input for the <ast> parameter is ignored.
However, one of the following values must be entered to ensure that the
bar-code command string is complete and valid. The options for the <ast>
parameter are:
0 = Do not automatically add start/stop characters.
1 = Automatically add start/stop characters.
NOTE
If value 0 is selected, you must manually enter start/stop characters
(asterisks) together with the data. Failure to add the asterisks will cause
an invalid bar code to be printed (that is, a bar code without start/stop
char-acters). If human-readables are being printed, the asterisks will
also print as human-readables.
If value 1 is selected, you must not add asterisks as start/stop
characters to the data. Failure to omit asterisks will cause an invalid bar
code to be printed (that is, a bar code with too many start/stop
characters).
<data>
:
The data to be printed as a bar code. Some bar codes require a certain
number of characters. Others only allow alphanumeric or numeric
characters. Before the Card processes the data string, it will check the
complete data string and verify that it is valid. This is why the “¬B” at the
end is so important. If an invalid data string has been entered, the Card
