Sandhar,
Those are questions that you can certainly pose to members of this bulletin board. Don't waste your money paying someone to answer such questions, when there are so many people going through the same thing you are and can try to help you.
Bottom line is, make sure that you are giving the best impression possible when you are filling our applications. In my personal opinion typing everything is the best way to go, especially if a person's penmanship is not so easy to read. Schools that have e-versions of their apps on the web usually ask that you fill them out, print them and submit the hard copies. This may vary with schools but that's just been my experience.
I know that it's sometimes hard to get a hold of a typewriter if you need one but hey, if you want to go to med school badly enough, I would think that you would do whatever it takes. Ask around and borrow one or rent one if you have to. In the scheme of things, it probably doesn't matter all that much but I would opt for being cautious and type everything as much as you can.
Best of luck to you.
