The physical act of writing engages the brain more than typing on a keyboard does. I claim that the physical motion and having to form shapes, as well as the more tangible spatial procession of your physical movement across the page reinforces the memory through association in a way that just pushing a key does not. Your hand is very intimately involved in making those marks on paper. Pushing buttons causes things to appear on a screen, but there is little tactile engagement and it isn't very differentiated (all pushes of a key are approximately the same). Writing is also more deliberate, whereas you can type while half asleep. The quality of your writing also depends on effort. Typed letters appear the same no matter how you press the key. You are mainly concerned about pushing the correct key, but how to press it is unimportant and there isn't much room for variation anyway.
