PQ-8P, PQ-8S
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 PQ-8
automatically calculates and causes
a check digit to be printed. The
following bar codes require a check
digit, so, the PQ-8 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 PQ-8.
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
PQ-8 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.)
