Looking for PDF solution via Adobe 9 or Adobe X reader, by creating PDF files for the purpose of gathering information as the .pdf user fills in the form fields via the internet, I will give you an example of an advanced .pdf currently in use:
https://www.1010ez.med.va.gov/sec/vha/1010ez/Form/1010ez.pdf
Giving the user the choice to Save, print, submit when finished, and also collecting the information as they are filling in the form itself, I know it will be expensive for this option, I don’t care.
