You could scan the blank form into a .jpg or .tif file, insert
the .jpg or .tif into the header of a Word document, format the
..jpg or .tif as "behind text", close the header of the Word
document, and draw text boxes formatted as "in front of text" in
the main document layer where you need to enter text.

The method suggested by Ainsworth is essentially doing the same
thing in Acrobat instead of in Word, but you need the full
version of Acrobat (not just the free Reader) to do it.

How can I enter text on this document? Any help would be greatly appreciated.
