PDF 417 Symbol Geometry
Automatic PDF 417 Bar Code Generation
The printer automatically tests and changes the PDF 417 bar code geometry to maximize the
readability of the bar code for a given maximum height and width, specified by p4 and p5.
The printer tests the PDF 417 parameters in this order for a given data string (error correction
and compression included):
1. Module width p10 (for codeword width)
2. Symbol width p4
3. Symbol column maximum p13
4. Module height p11
5. Symbol height p5
6. Symbol row maximum p12
The printer will start with the maximum value (default or explicit) for these parameters. The
printer reduces these values to get the module width and height to maximize readability.
