A/C-7P RO, A/C-7S RO
Width parameters are ignored
when printing POSTNET bar codes,
since POSTNET uses one standard
width. However, a valid value (1-9)
must be entered for the width
parameter to ensure the bar code
command string is complete.
<hr>: Identifies whether human-
readables are printed or not.
Human-readables are printed
underneath the bar code. Valid
values are:
0 = Do not print human readables.
1 = Print human readables.
<chkd>: Indicates whether the A/C-
7 RO automatically calculates and
causes a check digit to be printed.
The following bar codes require a
check digit, so, the A/C-7 RO
automatically generates and adds a
check digit to the bar-code data:
Code 128, POSTNET, UPC A, EAN
8, EAN 13
If any of the bar codes listed above
has been selected, the <chkd>
selection is ignored by the A/C-7
RO. However, one of the following
values must be entered to ensure the
bar code command string is
complete and valid. The options for
the <chkd> parameter are:
0 = Do not calculate and add a check
digit.
1 = Calculate and add a check digit
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
A/C-7 RO and input for the <ast>
parameter is ignored. However, one
of the following values must be
entered to ensure 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 (i.e. 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 (i.e. a bar code with a
start/stop character pair in
the beginning and a
start/stop character pair in
the end.)
