If the schools application is still mail-in form only, then I guess it is acceptable to fill it out by hand. Typing is more professional for essays, unless your handwriting and spacing abilities are perfect. You're in college (or done with it) so I imagine everyone can figure out how to type the applications if they require an essay of any sort. If you have a paper copy and absolutely no way else to type it, scan it in as a pdf and use adobe acrobat professional to create text boxes. Your school should have scanners and adobe software. There is always the typewriter too (although that might be a ltitle more difficult to come by.) Obviously for some people this will be too difficult (overseas, non-trad student with no access, etc.) but don't fail to type it because you're too lazy. 🙂
