To me, it sounds like he would like to print a form a bunch of times, then come back later and fill the form in, using his printer, like you might do with a typewriter.
So, the actual piece of paper would be run through a printer twice, the first time it would print the PDF, the second time it would print the filled-in parts (name, date, whatever). The second run would be a lot faster.
What for the3seashells? (if you don't mind me asking...)
Also, just in case you don't already know; there are programs that will let you do what tomos is saying: superimpose additional writing on a PDF which will let you print the original form and the filled-in parts all at once.
