How do I enable saving of filled-in fields on a PDF form?

Question

Some PDF forms can be saved, including all filled-in field data:

Answer 1

There is a setting inside the PDF file that turns on the allow saving with data bit. However, it requires that you have a copy of Adobe Acrobat installed to change the bit.

The only other option is to print it to a PDF print driver which would save the data merged with the pdf file.
