Option 51 (PDF417 Security/Truncation)
You can define a security level and choose whether or not to
truncate a PDF417 bar code. Higher security levels add data to a
bar code, improving scan reliability. Some damaged bar codes
may still be scannable if the security level is high enough. You
can use this option to create standard PDF417 bar codes or use
the truncated option to create a narrower bar code. This option
can appear only once per PDF417 field, in any order, following the
bar code field.
As the security level is increased, so is the size of your PDF417
bar code. For each level increased, the bar code will double in
size.
To use Option 51 on the 9820 printer, you
must have version 5.2 or greater.
