This example will print a PDF417 bar code with the following settings:

<<
Default
Value Definition
0 Optional; 0 – 8, default is 0
Designates error correction levels by predetermined values:
If the value is anything other than 0-8, a RANGECHECK is set.
Error correction can also be specified as a percentage. A valid
non-zero /Errorpercent value will override /ErrorLevel. See "/
Error Percent" on page 86.
Optional; not supported
Optional; not supported
false Optional; default is false (no truncation)
If true, right row indicator and stop pattern are omitted.
[150 150] Optional; in 1/600 inch; default is [150 150]
0 Optional; 0-400; default is 0
Designates error correction levels by percentage. Valid
percentage values range from 0% to 400%. Any values outside
this range will cause a RANGECHECK error. A valid non-zero
value will override /ErrorLevel. See "/ErrorLevel" on page 86. A
zero value will cause the /ErrorLevel value to be used.
If a valid non-zero percentage is specified, the error correction
level will be computed by selecting one of the /ErrorLevel values
(0-8).The error correction level selected will be the one that best
matches the number generated by multiplying the specified
percentage by the number of data code words in the symbol.
Example:
If there are 20 data code words in the symbol, and /
ErrorPercent is specified at 100% (100), then the /ErrorLevel
selected will be the one closest to 20, or /ErrorLevel 3 (16 error
code words).
For the same 20 data code words, and an /ErrorPercent of 35%
(35), /ErrorLevel 2 will be selected, because it is closest to 20 x
0.35, or 7.
%this is the data to be encoded
