PQ-8P, PQ-8S
<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 PQ-8
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 PQ-8 will print “Invalid Data” in
the place of the bar code.
NOTES
1. Valid values must be
entered for each of the
parameters specified above,
even if the parameter is
irrelevant for the type of bar
code being printed.
2. If an invalid parameter
value (other than invalid
data) has been entered, the
PQ-8 will process the bar-
code command up to that
point and then reject any
information it receives after
the incorrect value.
For example, a bar-code
command string has been
entered, however, an invalid
<hr> value of 3 has been
specified.
¬B2,6,6,3,0,0,code128_B
The PQ-8 would cause all
characters after the invalid
value 3 to be printed:
,0,0,code128
This helps quickly
identify where the mistake
occurred.
3. Spaces in the bar-code
command string are invalid
and will lead to the same
result as mentioned in Step
2.
4. If invalid data (either too
many characters or the
wrong type of characters) is
entered, the PQ-8 will print
the error message:
** Invalid Data **
5. Allow for sufficient vertical
spacing when printing text
data beneath the bar code.
For example, when the bar code
command sting is entered on line 1
of the document with a bar code
height specified as 5 (approximately
1/2 inch or 3 lines at 6 LPI), and
text is then entered on line 2 as
follows,
¬B5,7,1,0,0,0,1234567890¬B
This data overrun by barcode
this will cause the bar code to
overlap the text in the second line:
