will print “Invalid Data” in the place of the bar code.
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 Card will process the bar- code command up to that point
and then reject any information it receives after the incorrect value.
For example, suppose a bar-code command string has been entered,
but an invalid <hr> value of 3 has been specified:
¬B2,6,6,3,0,0,code128¬B
The Card 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 result described in paragraph 2.
4. If invalid data (either too many characters or the wrong type of
characters) is entered, the Card will print the error message “** Invalid
Data **”
5. Allow for sufficient vertical spacing when printing text data beneath
the bar code. For example, let’s say the bar-code command string below
is entered on line 1 of the document with a bar-code height specified as
5 (approximately
1
⁄
2
” 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
When you print it, the bar code will overlap the text in the second line:
To avoid overlapping bar codes with text, always allow for sufficient
vertical line spacing (by adding line feeds, for example) to accommodate
the height of the bar code.
6. When text data is entered to the right of the bar-code command
string, the printed text will appear immediately to the right of where the
