Option 51 (Pdf417 Security/Truncation) - Paxar TC6037PR Reference Manual

O p t i o n 5 1 ( P D F 4 1 7 S e c u r i t y / T r u n c a t i o n )
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.
