I got frustrated writing my applications (such as USCs and Washington State Univ) because I have ugly handwriting, so I searched throughout the internet for a freeware to be able to type in pdfs. In the end, I asked some computer people if they had adobe professional software and went on a fatwallet forum and found foxit reader. I downloaded the foxit reader and ghostwriter (both freewares and no problems yet of installed spyware and viruses)....and now I can make text boxes and type into these forms. Plus, you can save the data in the pdf so you'll never have to retype it. The downfall is that if you make a typo, then you'll have to redo it. I thought the quality was decent. It beats using a typewriter and photocopying it.
Try foxit reader (but you need ghostwriter).
Hope this helps.
