Suppose you were an astronaut on a space ship in the near future. Or an on an asteroid mission where little to no gravity is available. In such a situation it would be difficult to justify taking a large supply of blank paper. Perhaps you might have a few blank notebooks in your personal allowance but those will only let you so long. 

So, how do you go about producing more paper for yourself? What are good feedstocks? Or how might you modify typical paper making techniques for micro gravity? 

I am looking for science-based answers for a near future setting. Exactly how near future is not important.
